Annotated Bibliography vs. Literature Review

What's the big deal.

There are fundamental differences between an annotated bibliography and a literature review that are crucial to completing the assignment correctly. The chart below is provides an overview of the biggest differences between the two types of assignments in a side-by-side comparison. However, if you need more specific information about either assignment, visit our Annotated Bibliography and/or Literature Review pages for more detailed information on how to complete them.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

Research Methods at SCS

• Basic Strategies

Literature Reviews

Annotated bibliographies, writing the literature review, matrix for organizing sources for literature reviews / annotated bibliographies, sample literature reviews.

• Qualitative & Quantitative Methods
• Case Studies, Interviews & Focus Groups
• White Papers

A literature review is a synthesis of published information on a particular research topics. The purpose is to map out what is already known about a certain subject, outline methods previously used, prevent duplication of research, and, along these lines, reveal gaps in existing literature to justify the research project.

Unlike an annotated bibliography, a literature review is thus organized around ideas/concepts, not the individual sources themselves. Each of its paragraphs stakes out a position identifying related themes/issues, research design, and conclusions in existing literature.

An annotated bibliography  is a bibliography that gives a summary of each article or book. The purpose of annotations is to provide the reader with a summary and an evaluation of the source. Each summary should be a concise exposition of the source's central idea(s) and give the reader a general idea of the source's content.

The purpose of an annotated bibliography is to:

• review the literature of a particular subject;
• demonstrate the quality and depth of reading that you have done;
• exemplify the scope of sources available—such as journals, books, websites and magazine articles;
• highlight sources that may be of interest to other readers and researchers;
• explore and organize sources for further research.

Structure of a Literature Review

Preliminary steps for literature review.

• Basic Example
• More Examples

What is a Literature Review?

A literature review is a comprehensive summary and analysis of previously published research on a particular topic. Literature reviews should give the reader an overview of the important theories and themes that have previously been discussed on the topic, as well as any important researchers who have contributed to the discourse. This review should connect the established conclusions to the hypothesis being presented in the rest of the paper.

What a Literature Review Is Not:

• Annotated Bibliography: An annotated bibliography summarizes and assesses each resource individually and separately. A literature review explores the connections between different articles to illustrate important themes/theories/research trends within a larger research area. 
• Timeline: While a literature review can be organized chronologically, they are not simple timelines of previous events. They should not be a list of any kind. Individual examples or events should be combined to illustrate larger ideas or concepts.
• Argumentative Paper: Literature reviews are not meant to be making an argument. They are explorations of a concept to give the audience an understanding of what has already been written and researched about an idea. As many perspectives as possible should be included in a literature review in order to give the reader as comprehensive understanding of a topic as possible.

Why Write a Literature Review?

After reading the literature review, the reader should have a basic understanding of the topic. A reader should be able to come into your paper without really knowing anything about an idea, and after reading the literature, feel more confident about the important points.

A literature review should also help the reader understand the focus the rest of the paper will take within the larger topic. If the reader knows what has already been studied, they will be better prepared for the novel argument that is about to be made.

A literature review should help the reader understand the important history, themes, events, and ideas about a particular topic. Connections between ideas/themes should also explored. Part of the importance of a literature review is to prove to experts who do read your paper that you are knowledgeable enough to contribute to the academic discussion. You have to have done your homework.

A literature review should also identify the gaps in research to show the reader what hasn't yet been explored. Your thesis should ideally address one of the gaps identified in the research. Scholarly articles are meant to push academic conversations forward with new ideas and arguments. Before knowing where the gaps are in a topic, you need to have read what others have written.

As mentioned in other tabs, literature reviews should discuss the big ideas that make up a topic. Each literature review should be broken up into different subtopics. Each subtopic should use groups of articles as evidence to support the ideas. There are several different ways of organizing a literature review. It will depend on the patterns one sees in the groups of articles as to which strategy should be used. Here are a few examples of how to organize your review:

Chronological

If there are clear trends that change over time, a chronological approach could be used to organize a literature review. For example, one might argue that in the 1970s, the predominant theories and themes argued something. However, in the 1980s, the theories evolved to something else. Then, in the 1990s, theories evolved further. Each decade is a subtopic, and articles should be used as examples. 

Themes/Theories

There may also be clear distinctions between schools of thought within a topic, a theoretical breakdown may be most appropriate. Each theory could be a subtopic, and articles supporting the theme should be included as evidence for each one. 

If researchers mainly differ in the way they went about conducting research, literature reviews can be organized by methodology. Each type of method could be a subtopic,  and articles using the method should be included as evidence for each one.

• Define your research question
• Compile a list of initial keywords to use for searching based on question
• Search for literature that discusses the topics surrounding your research question
• Assess and organize your literature into logical groups
• Identify gaps in research and conduct secondary searches (if necessary)
• Reassess and reorganize literature again (if necessary)
• Write review

Here is an example of a literature review, taken from the beginning of a research article. You can find other examples within most scholarly research articles. The majority of published scholarship includes a literature review section, and you can use those to become more familiar with these reviews.

Source:  Perceptions of the Police by LGBT Communities

There are many books and internet resources about literature reviews though most are long on how to search and gather the literature. How to literally organize the information is another matter.

Some pro tips:

• Be thoughtful in naming the folders, sub-folders, and sub, sub-folders.  Doing so really helps your thinking and concepts within your research topic.
• Be disciplined to add keywords under the tabs as this will help you search for ALL the items on your concepts/topics.
• Use the notes tab to add reminders, write bibliography/annotated bibliography
• Your literature review easily flows from your statement of purpose (SoP).  Therefore, does your SoP say clearly and exactly the intent of your research?  Your research assumption and argument is obvious?
• Begin with a topic outline that traces your argument. pg99: "First establish the line of argumentation you will follow (the thesis), whether it is an assertion, a contention, or a proposition.
• This means that you should have formed judgments about the topic based on the analysis and synthesis of the literature you are reviewing."
• Keep filling it in; flushing it out more deeply with your references

Difference Between a Literature Review and an Annotated Bibliography

Literature review.

A literature review should not be confused with an annotated bibliography. A literature review is not simply a summary of information you have found on a topic. Literature reviews are more in depth and provides analysis of multiple works relating to a research question. An annotated bibliography is a list of the resources, that you consulted when working on a research project. Each citation is accompanied by a brief written analysis of its usefulness to your research.

Purdue Owl Annotated Bibliographies

Purdue owl annotated bibliography information, annotated bibliography breakdown, stem cell research: an annotated bibliography.

Holland, Suzanne. The Human Embryonic Stem Cell Debate: Science, Ethics, and Public Policy . Boston: MIT P, 2001.

This is the annotation of the above source, which is formatted according to MLA 2016 (8 th ed.) guidelines for the bibliographic information listed above. If one were really writing an annotation for this source, one would offer a brief summary of what this book says about stem cell research.

After a brief summary, it would be appropriate to assess this source and offer some criticisms of it. Does it seem like a reliable and current source? Why? Is the research biased or objective? Are the facts well documented? Who is the author? Is she qualified in this subject? Is this source scholarly, popular, some of both?

The length of your annotation will depend on the assignment or on the purpose of your annotated bibliography. After summarizing and assessing, you can now reflect on this source. How does it fit into your research? Is this a helpful resource? Too scholarly? Not scholarly enough? Too general/specific? Since "stem cell research" is a very broad topic, has this source helped you to narrow your topic?

Senior, K. "Extending the Ethical Boundaries of Stem Cell Research." Trends in Molecular Medicine , vol. 7, 2001, pp. 5-6.

Not all annotations have to be the same length. For example, this source is a very short scholarly article. It may only take a sentence or two to summarize. Even if you are using a book, you should only focus on the sections that relate to your topic.

Not all annotated bibliographies assess and reflect; some merely summarize. That may not be the most helpful for you, but, if this is an assignment, you should always ask your instructor for specific guidelines.

Wallace, Kelly. "Bush Stands Pat on Stem Cell Policy." CNN . 13 Aug. 2001.

Using a variety of sources can help give you a broader picture of what is being said about your topic. You may want to investigate how scholarly sources are treating this topic differently than more popular sources. But again, if your assignment is to only use scholarly sources, then you will probably want to avoid magazines and popular web sites.

What is a Literature Review?

Literature Review - from The Writing Center at UNC Chapel Hill

A literature review discusses published information in a particular subject area, and sometimes information in a particular subject area within a certain time period. It usually has an organizational pattern and combines both summary and synthesis. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information. It might give a new interpretation of old material or combine new with old interpretations. Or it might trace the intellectual progression of the field, including major debates.

Organizing a Literature Review

There is not one "standard" for literature reviews but they should include the following:

• Introduction: Gives a quick idea of the topic of the literature review, such as the central theme or organizational pattern.
• Body: Contains your discussion of sources and is organized either chronologically, thematically, or methodologically (see below for more information on each).
• Conclusions/Recommendations: Discuss what you have drawn from reviewing literature so far. Where might the discussion proceed?

Organizing your literature review:

• Chronological: If your review follows the chronological method, you write about your materials according to when they were published. The oldest date is first and the most recent publication date is last.
• By publication: Order your sources by publication chronology, then, only if the order demonstrates a more important trend.
• By trend: A better way to organize sources chronologically is to examine the sources under another trend, such as the history of whaling. Then your review would have subsections according to eras within this period.
• Thematic: Thematic reviews of literature are organized around a topic or issue, rather than the progression of time. However, progression of time may still be an important factor in a thematic review. For instance, a thematic review of material on sperm whales might examine how they are portrayed as "evil" in cultural documents. The subsections might include how they are personified, how their proportions are exaggerated, and their behaviors misunderstood. A review organized in this manner would shift between time periods within each section according to the point made.
• Methodological: A methodological approach differs from the two above in that the focusing factor usually does not have to do with the content of the material. Instead, it focuses on the "methods" of the researcher or writer. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Prevent plagiarism, run a free check.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

Audio: Hello, everyone. Welcome to today's webinar regarding lit reviews and annotated bibliographies. My name is Michael Dusek and I'm really happy to be leading this webinar today, excited. Essentially what we are going to be doing is we’re going to be taking a look at these two genres at these two written genres. Both the literature review and the annotated bibliography. We’re going to discuss some conventions. Or some typical characteristics that you might see or encounter in literature reviews and annotated biliographies. And we’re just going to go through general formatting and organizational tips as to how to organize these documents and get them to a place where they are useful to both you and to your reader.

Audio: So that was kind of my broad stroke overview. Here are the more specific objectives of this particular webinar. We will overview these things. We are going to talk about conventions of these two genres, the purpose of them, what are they meant to accomplish? I think the literature review and annotated bibliography are somewhat related, but they really are meant to accomplish different things; they have different purposes.

We are going to look at the formatting and organization of these documents which are significantly different. So, we are going to see how they are different and how one could perhaps inform the other. We are going to look at writing tips and some examples of this, some things that can save you time and perhaps some anxiety and headaches and some examples to show you how these are typically formatted and what they look like typically in the academic community.

And lastly as I mentioned, we are going to discuss the relationship between the two genres, and how one can lead into the other and how really these are some ways working with the same materials even though they are doing pretty significantly different things.

Audio: But, yeah, to break this down a little, to talk about these, alternative names, you can see this is an annotated bib. Right? This is kind of a shortened version of a bibliography there. For annotated, a part of annotated bibliography, think of annotated as really anything. Any time you are interacting with a source.

A broad definition of annotation is any mark that you make in a document. So, if you are highlighting something, if you are underlining a piece that you’re working with, maybe writing some notes in the margin or putting a question mark next to something that you need to look up, these are all considered annotations. For the purpose of annotated bibliography, it's sufficient to think of this as working with a draft or working with a source, excuse me, working with a piece of scholarship you might potentially use in your research.

Lit review is a shortened version of word literature review. These are really used interchangeably. If you see these shortened versions, you can assume that they are referring to these two documents or one of the two.

Visual: Slide changes to the following: The Annotated Bibliography

Annotate : “to make or furnish critical or

explanatory notes or comment”

Bibliography : “the history, identification, or

description of writings or publications”

                          (Merriam-Webster’s Online Dictionary, 2012)

Audio: So, to begin with then, let's pick one. And for the purpose of this webinar we pick the annotated bibliography to start with. But before we get into breaking this up, I want to talk about how the annotated bibliography is primarily a research tool. It is meant to aid you in collecting your research and kind of sussing out both what this source is doing; how it could do this thing better. And then how this might be useful or applicable to you in your research.

But to ground this, I want to start with the foundation that an annotated bibliography is a research tool. It's meant to help you organize your research. Right? Okay.

Now that we’ve established that foundational definition here, let's break up these two words. Annotate, to make or furnish critical or explanatory notes or comments. Yeah, it's to work with a draft. As you guys are scholars now, in a higher level of post-secondary level here, generally speaking, you really can think of yourself as professional readers. When you read a scholarly source or read a source you are thinking of using in your research, you don't want to be a passive party to that. You want to actively engage with that source and annotations are part of doing this. Making notes in a source, underlining things, highlighting things that you may need to look up again. These are all considered annotations. But, again, for the purpose of this discussion, an annotation is really working with a source, is this kind of critical or explanatory note that you provide for that source.

A bibliography is defined by Merriam Webster, as the history or identification or discription of writings or publications. Really what we are looking for here is publication information, history, identification, description; where is this source coming from. Right? Where are you getting this from and how does this compile into a list of other sources on a related topic.

I know that's a little wishy washy on the second part of this definition, but this is going to become a little bit more clear as we take a look at how to compile this, what elements go into, an annotation or annotated bibliography entry, and that will be a little bit more clear as we go on here.

For those of you looking for a resource outside of this webinar discussing annotated bibliographies, in the bottom right corner of this slid, you can see we have a link to our annotated page. What this is, it's a website, web page, that explains how annotated bibliographies work, the elements that need to be included in a typical annotated bibliography. And it gives you an example of what an annotated bibliography could look like, as well as should look like, better said. So, if you are watching this recording or downloaded the slides and want to refer to a resource about this topic after the fact, after this webinar, this is a great one. Right there on the bottom right.

Visual: Slide changes to the following: Annotated Bibliography: Purpose

• Teaches about a particular topic
• Demonstrates a source’s value
• Shows depth/breadth of research
• Helpful note-taking and reflection exercise
• Promotes analysis and critical reading
• Preparation for a writing project

Audio: Thinking about the purpose of annotated bibliographies, you can think of it as certain purposes for the reader. It has certain purposes for yourself. As I mention, this is primarily used as a research topic, but a research tool, excuse me. But it's not uncommon to get an assignment to complete an annotated bibliography within a course. So, there's something of a reader awareness or a purpose for the reader, as well as for you, the researcher, compiling this.

So, for the reader what an annotated bibliography can do. Is it can inform the reader about a particular topic. It can demonstrate a source's value or why a source is important within a topic area, and it can show depth or breadth of research. And annotated bibliography is generally going to consist of a many entries. Throughout your research process you are going to continue to add to this probably, but it's going to show again a breadth of research, what information is out there on a topic.

For yourself, again, this is a research tool. This is helpful in note taking and reflecting on your source. A lot of the difficulty of writing is knowing where to look and being able to save yourself time in referring to a source that you’ve already read can be valuable in that you don't have to reread that source. You can look at an annotated bibliography and say that's what that source is about and here's why I thought it was useful to me in my research process. So really, it's to save you time, promotes analysis and critical thinking.

With an annotated bibliography pushes you to do, is not just summarize a source, but critique it and take that critical eye to it. One of the paragraphs in an annotated bibliography focuses specifically on critiquing that source. What is that source doing well, what could that source do better, perhaps. And in this way you are joining that conversation as a scholar. So this does this as well.

So lastly it prepares you for a writing project. It's a way of compiling your research so that you can kind of have it all in one place before you get off and get towards creating and outline or drafting. It's a place to store the research that you have already done, so in that way it can be really valuable.

• Course assignments
• Prewriting for large projects

Audio: Where will you encounter annotated bibliographies? As I mentioned you might see these in course assignments. When I would teach writing, this would not be uncommon for me to give students. Walden will assign an annotated bibliography as a beginning or as a jumping off point to a larger research project. I think they do this because they think that this is an important element in the research process. So yeah, you might encounter these as course assignments. Beyond that, for those of you working on a larger project like a capstone or a dissertation document, these are really meant as a prewriting strategy, or again, a tool, to allow you to approach that larger piece more efficiently and being from a place of being more informed. You will research more and you will be more informed individually about that topic. But it's not uncommon to see these in course assignments. So, there's a do it for the professor side and there’s the do it for yourself side. And as you get to these capstone or dissertation documents, the do it for yourself to save yourself the anxiety, is going to become the dominant purpose here. But alas you might see these in course assignments too.

Visual: Slide changes to the following: Annotated Bibliography: Format & Organization

Alphabetized list of reference entries + annotations

Reference entry listed in alphabetical order.

                             Annotation of source in paragraph format.

Reference entry.

                             Annotation.

Audio: Okay. Talking about formatting and organizing, annotated bibliography, the first thing to note, is that these are like a reference list. These are going to be alphabetized. So, you’re going to start with the sources that begin with A in their reference entry. This is kind of a brief out line here that discusses this. So, as you can see, you will start with a reference entry in alphabetical order. And then you’re going to below that, put your annotations. These are a number of paragraphs that we are going to break apart in an upcoming slide, but for the purposes of right now you can think of an annotated bibliography or each annotation, as having two pieces. You are going to have your reference entry, which is APA formatted. Looks like a reference entry at the end of a piece you have composed. And you are going to have your annotation part.

So, these two parts. Again, as I mentioned the annotation part is going to be broken down further, but let's start here for now, shall we. And this is how this is going to look in this brief outline, you’ll have a reference entry, and below it you’ll have your annotation piece and you will keep listing those sources in an alphabetized order there.

• Reference :
• Common Reference List Examples
• Annotation :
• 3 paragraphs: Summary, Analysis, and Application
• 2 paragraphs: Summary/Analysis and Application
• Depends on your purpose and faculty’s expectations

Audio: And to break this down a little farther as I promised, as I said that I would do. You start again with this reference entry that is in APA formatting. A helpful resource that I know I use a lot and I think, I know Claire uses allot too, is this link here for common reference list examples. What this link has is, it provides some formatting for some commonly used sources. Things like journal articles, like books, like web pages. Even down to things like course materials or interviews and these types of things. It will have a number of different formats and each source has a different formatting. Right? This link will give you some examples of those that you can use as examples to double check that your reference entries are correct.

Now this second part, as I mentioned, can be kind of broken down into a number of parts. This annotation. And for this you’re going to use consistent paragraph formatting. It will be double spaced. But this annotation part often times is broken down into two to three paragraphs. Right? In a three-paragraph annotation you’re going to have one paragraph that summarizes the source, what does it say, what are these authors doing, what are their conclusions and what does this study find. You are going to have a paragraph analyzing or criticizing the source. What did this piece do well, what are some opportunities for this piece to have been better? Is there potentially opportunities for furthering research that this piece brought up. Right? That would be another kind of analysis piece.

And lastly, in a three-paragraph annotation you’re going to have an application paragraph which essentially states why this piece is important broadly in that, in your field. But more importantly, how is this piece useful for your resource process, in your resource project. Something that would be typical to include in an application paragraph would be something like, I feel I'm going to use the data from page 12 on, in my background section or something like this. My point is, is that this is how this applies to you, how is it useful in your specific research product.

A shorter version of an annotation can only have two paragraphs, where you combine the summary and analysis and then have a separate application paragraph. In an even simpler annotation maybe for yourself as you’re reading a number of sources, you might just have a summary paragraph. But my point is, there's a number of ways to do this. If you are encountering this as a course assignment it's likely the professor is going to ask you to include a three-paragraph annotation. If you are doing this on your own, and this is not part of a course assignment, this is just a research tool for you, you can choose to format this however you want. Right? Because it's about finding what is useful to you personally. This is the format that we think is quite effective. And, again, in course assignments where you’re being assigned an annotated bibliography to complete it's usually going to be either one of these two and I would say primarily the three-paragraph annotation.

And again, it expands on your purpose and the faculty expectations. I would like to remind you guys, it is certainly appropriate to reach out to your faculty and to ask those questions. To clarify: Are you expecting a three-paragraph annotation or is a two-paragraph appropriate for this piece. I guess the reason I say this, often times I find students are a little reticent about contacting professors with questions, but I want to reassure you this is an appropriate question to reach out to your faculty or to your professor with.

Visual: Slide changes to the following: Annotated Bibliography: Writing Tips

• Take factual notes
• Use the past tense
• Use your own words
• Focus on purpose, methods and findings
• Include the most relevant information
• Take questioning notes
• Focus on strengths and then weaknesses
• Go broad à narrow
• Do not feel the need to be “nice.”
• Take notes of your reactions
• Relate the source to yourself, your field, other scholars, the community, etc.
• How could this source be useful?
• Potentially use “I”

Audio: To break this down a little further from the annotation piece here, a summary paragraph is going to be your first paragraph of your annotation. And again, this is factual notes. This is what your summarizing this piece. You want to use the past tense. In APA, specifically you want to use past tense when referring to pieces that have already been published. A good way to think about this, is this has been already said. As it was published, say, in the year 2012, it has already been said in the year 2012 so it is appropriate to discuss that piece in the past tense.

In your summary paragraph you’re going to use your own words. Really you want to focus on the purpose, the methods and the findings of the study. What did the study set out to do, how did they plan to accomplish that goal or test that hypothesis? And then at the end what did they find. Right? What were their conclusions, what were they able to draw from this study?

And in your summary when thinking about what to include and what to omit, what to leave out, you really want to include the most relevant information there. Right? What’s the meat of this study, what did these authors really look for and what did they really find. These are things to include, maybe smaller pieces about the methodology or some smaller details that the author includes that didn't turn out to be as important to the conclusions of the study. These can be things to omit. But again, it's what relevant to your research topic. That's the information that should be included in the summary paragraph.

Now, the analysis paragraph, your second paragraph of an annotation, I often refer to as the critique paragraph, is really about bringing this critical eye to your engagement with the source. Right? You want to take questioning notes. Focus on the strengths and on the weaknesses of a source. Right? What could this source have done better. We’re going to look at a couple of examples later on in this presentation of some ways to critique a source and to pick apart ways a source that could have tested something more accurately.

In an analysis paragraph you want to start broadly and work specifically. Broadly this study is doing this well, more specifically it could do this better. That's a general way to approach an analysis paragraph.

And lastly, don't feel the need to be nice here. I think this is an important point about scholarship at the graduate or PhD level in general, and that's that you’re entering this conversation. Right? So, it's okay to disagree with the author. I would encourage you to keep a professional tone, but it's okay to encounter a study where you say I don't think this is a very accurate study for these three reasons. That's okay. That as a scholar, someone who studies in this field and who is familiar with scientific methods and other ways to test hypotheses, it's appropriate for you to add your voice to this even if it's in disagreement. Just a general note for you all there.

Your last paragraph again, is this application paragraph. Take notes as to your reactions. That's a good tip there. But again, you want to relate the source to yourself, to your field, to other scholars, to your intellectual communities that you are a part of, etcetera, in an effort to recognize how this could be useful to you and to your research project. 

So, again, to simplify this a little bit, a good application paragraph will talk about maybe the significance of the study in the field; so, and so study is foundational in the field of psychology because it studied X, Y and Z that produced a lot more research. That would be an appropriate detail to include in an application paragraph. But, again, where it's most important to you as a researcher would be this, how it is useful to my research product; I would like to use the methodology of this study to then test a different hypothesis in my dissertation. Something like that. But, again, it's going to be different for every person. But the application paragraph, as you think about this as you approach this, the important part is how is this source useful to me. That's how it applies. That's where the rubber meets the road here. So, again, a typical annotation has three paragraphs and each does something significantly different.

Visual: Slide changes to the following: Annotated Bibliography:

• Summary Paragraph

       Thompson, Kirk, and Brown conducted a study to determine how burnout and emotional exhaustion of female police officers affect their family environment based upon role ambiguity and role overload.  Thompson et al. mailed out surveys to 1,081 female police officers employed by the Australian State Police; however, only 421 surveys were useable.  The researchers predicted that supervisor support would reduce role stressors and emotional exhaustion and improve family cohesion and conflict.  They found a relationship between supervisor support and reduced role stressors, family functioning, and emotional exhaustion, but did not find a correlation between coworker support and work stress.  Thompson et al. suggested that further research is needed on how emotional exhaustion affects family stressors in policewoman.

Audio: Next we’re going to have some examples of these. For the summary paragraph I don't think I'll read this whole thing because I think at this level you guys are familiar with summarizing a piece, but this is what this could look like. (Reading) Thompson Kirk and Brown conducted a study to determine how burnout and emotional exhaustion of female police officers affect their family environment based upon role ambiguity and role overload.

This goes on to summarize the rest of this piece. As you can see it talks about the sample size here. It talks about the methodology. This male survey thing. And at the end it talks about these findings. They found a relationship between supervisor support and role stressors.

To get back to our slide and in an example here, what this does is talks about what the authors were looking to find, it talks about how they plan to find that or test that hypothesis, and then at the end it talks about what they did find. The conclusions of that piece. So, you can see all the parts are here.

One thing that’s important to note as we look at this example as you can see there are no citations here. Right? In an annotated bibliography the reason why often times we don't include citations, this can be seen a bit as redundant. So, if you have a reference entry above your annotations it's kind of implied that what follows here based on the genre of annotated bibliographies is a summary critique and an application of the above source.

However, in some course assignments you may be required to cite within the paragraphs of an annotated bibliography. So that would be the expectation of the instructor and the purpose which you are using this for. If you are using this annotated bibliography as a research tool, you don't need to necessarily include citations there because you know where you are drawing this from. If you are turning this in for a grade you might want to include citations, because that's conventional in APA formatting in general. But if you have a question about this, this is something to reach out to your professor about and would be a perfectly appropriate question to ask. To wrap up this slide, the summary paragraph it summarizes. You talk about what the study is doing.

• Analysis Paragraph

Although Thompson et al. made a significant contribution to the field of police research, the article had several limitations.  First, the researchers chose a small and specialized sample that did not include policewomen or other minorities.  Second, the researchers potentially influenced results by asking leading questions in the interviews and focus group meetings.  Therefore, further research is needed with a wider demographic range and completely impartial interviewers.

Audio: The analysis paragraph, then you are working with this piece. Right? You are talking about the strengths and the weaknesses. Although (reading) Thompson, et al made a significant contribution to the field of police research, the article had several limitations.  First, the researchers chose a small and specialized sample that did not include policewomen or other minorities.  Second, the researchers potentially influenced results by asking leading questions in the interviews and focus group meetings.  Therefore, further research is needed with a wider demographic range and completely impartial interviewers.

Now again, this has a professional tone. But you can see the author in this example analysis paragraph is really pointing out the shortcomings of this study. After reading it and evaluating the methods that this study, this hypothetical study uses, this author concluded that it could be done better in a couple of ways. There could be a wider sample size and there could be an impartial questionnaire or an impartial person asking the questions. So, it's in this way you can really work with the source and point out some ways it could be done better. That's really what the critique or analysis paragraph is all about. What did the study do well, but also what is it not doing so well? What are some opportunities for the study to have been more accurate or been done better more broadly?

Visual: Slide changes to the following: Annotated Bibliography

• Application Paragraph

This study was valuable to understanding the relationship between employees’ views of change and the coping mechanisms used. Based on the results, the business sector should reinforce positive emotions to reduce withdrawal and increase commitment to the change. This implication aligns with Kotter’s 8-step change model emphasizing the positive and reinforcing employees for their efforts. This study, as well as Kotter’s model, will serve as the basis for the Business Change Strategy of my Application.

Audio: Excuse me. Lastly, we are going to, you would include an application paragraph. And as I mentioned, this is where the rubber meets the road as a researcher. Here’s what an application would sound like. (Reading) This study was valuable to understanding the relationship between employees’ views of change and the coping mechanisms used. Based on the results, the business sector should reinforce positive emotions to reduce withdrawal and increase commitment to the change. This implication aligns with Kotter’s 8-step change model emphasizing the positive and reinforcing employees for their efforts. This study, as well as Kotter’s model, will serve as the basis for the Business Change Strategy of my Application.

So, as you can see here, this author is talking about what this study does well and how it contributes to this larger field. How it is applied to the field in general. In this case comparing it to Kotter's eight step change model. And then at the end is where this author talks about what this is study means to their project. This is going to serve as the basis for my application of a business strategy change. So yeah, the application is what are you going to do, how is this useful to you?

All Together

Audio: Altogether then, it can look something like this, start off with this reference entry. We then have our summary, our analysis paragraph and our application paragraph.

Let’s Take a Look!

Annotated Bibliography Example

Audio: So, let's take a look at what this can actually look like on paper. What this is formatted like on an entire annotated bibliography. As you can see we start with this title page. As we go on this starts with something of an introduction paragraph, something to lead the reader in and introduce them to the topic this annotated bibliography will be covering.

As a note here, not all professors are going to require you to have an introduction paragraph in your annotated bibliography, but I would recommend if you are turning it in for a grade and the reason is you want to bring the reader up to speed and tell them what topic this annotated bibliography will be covering, I think it's really important in general to give the reader enough background information to understand what you are doing in any piece. So, if you turn this in for a grade, I would recommend an introduction paragraph.

But as this is a research tool, if you are, you don't necessarily need that if you are just using it for your own research. If it's not being turned in and you don't think an introductory paragraph is important, by all means don't include one. But moving on, to take a look at this. We have our first annotation here. Starting with a reference entry. It goes on to have our three paragraphs, of one being a summary, the second an analysis or a critique, and the third being an application. And then it ends. We have another reference entry here that starts another annotation.

This is exactly how these are typically listed, one annotation after the other. You can see that they are alphabetized. And lastly, it is typical and conventional to include a reference list at the end of the piece. Again, as with citing within the piece, some professors and some instructors might find this to be redundant. I would have a hard time disagreeing with them. But this is something that you might be required to include also. So, if that's the case, definitely include that.

One reason I guess to the contrary I would say you should include a reference page, is that you can take these reference entries from here and then just plug them into your document once you are drafting. You have compiled these reference entries, so you can kind of just copy and paste there if you wish. But again, this is really up to the instructor's discretion as to whether or not you need to include this reference list. 

Let’s take a Look!

Audio: Okay. So that was kind of the first bit here about annotated bibliographies. I think this would be a good time to stop for questions.  Claire is there any questions in the Q & A box that you think the large group would benefit from me explaining or talking through?

Claire: Sure, thanks Michael We did have one and it was about the analysis or critique paragraph, that second paragraph in the annotated bibliography. Other than biases, are there other things that students could kind of talk about in that section or that are covered depending on the assignment?

Michael: Sure. That's a great question. Identifying bias in a source is really an important point and something as scholars you really want to be on guard for always, is when a piece is displaying some type of bias. That's one thing you can talk about in that analysis or critique paragraph. Other than that, really anything that you see as being something of a deficiency in a study. So, in our example one thing that they commented on was sample size. And this is something I think that's really common to look at.

In a study, a study has a specific sample or population they are look at or testing. This is something that can be easily manipulated and that isn't always generalizable to a larger population. So, if a sample size is too small, then the implication there is that you can't say the findings are generalizable to the rest of the population. So, sample size is one thing that I see commented on a lot there.

As in our example, again, this kind of the way a question is asked or the method, the methodology of the study would be better said here is another thing that is commented on a lot in a critique or analysis paragraph. How could this study have been done better would be another question to ask? And one often times the answer is the methodology could have been more sound. To refer to our example once more, if you are asking leading questions or if you’re asking questions that have some bias in them inherent, then you could write better questions. That would be another way to approach critiquing or using your own analysis on a study.

Generally speaking, though, it's really anything that you see that can be done better in a study. So, I mentioned a couple here, but there are many more, there are many more ways that a study can be done better. So, finding those and pointing those out is really what the analysis and critique paragraph is really all about. Any others Claire?

Claire: No, That was really great. Thank you, Michael.

Michael: Cool. All right. So that's our annotated bibliography section of this webinar.

Visual: Slide changes to the following: Relationship Between Annotated Bibliographies & Literature Reviews

Annotated bibliography = preparation for any writing project

Literature review = foundation for research

Audio: (laughing) Moving on then. We are going to talk a little bit about the relationship between annotated bibliographies and literature reviews. In an effort to kind of transition to talk about lit reviews.

So, to kind of ping pong off this slide here, annotated bibliography is something that's really meant to prepare you for any writing project. It's a research tool that you can use to inform a project of any length, essentially. A literature review is going to be a foundation for the research that you are conducting. So, an annotated bibliography compiles the research out there that you looked at. A literature review talks about the specific studies that are applicable to your narrowed topic that you are then going to be building from in your research project. So that's a little wishy washy, but I'm going to unpack how a literature review function differently. So, I'm hoping this will be clear as we get towards the end of this webinar and I think it will. So, stick with me.

Visual: Slide changes to the following: The Literature Review

“a written approach to examining published information on a particular topic or field. Authors use this review of literature to create a foundation and justification for their research or to demonstrate knowledge on the current state of a field.” (Walden Writing Center, n.d., para. 1)

More Resources!

“Reviewing the Literature and Incorporating Previous Research ” recorded webinar

Audio: The literature review, to use our definition here, is a written approach to examining published information on a particular topic or field. Authors use this review of literature to create a foundation and justification for their research or to demonstrate the knowledge on the current state of the field.

Yeah. That's a great definition. (Laughing). Really what I think about literature review as, its something that, it's a portion of a larger document. Right? That shows the reader what research is out there already on a narrowed topic.

One metaphor that people often use to talk about a literature review is that a literature review it's like a dinner party. So, each source is a scholar in this field and they are talking to each other about the specific topic. The literature review is, to go off this analogy, is compiling what is said at that conversation and that dinner table. Right? What are these different sources adding on this topic. How are they agreeing, how are they disagreeing? And you use that as the definition indicates, as a foundation for your own research. So, having this conversation in front of me, I think that the next place for this conversation would go in this direction. That's how the literature review functions.

More resources here on the bottom right hand corner. We have another webinar that discusses reviewing the literature and incorporating previous research specifically. If that’s something that interests you, go ahead and take a look at that too. Again, you are developing a foundation for your own research and telling the reader what research has been done on an narrowed topic already.

Visual: Slide changes to the following: Literature Review: Purpose

• Overviews your chosen topic or field
• Demonstrates your depth of knowledge
• Can show a gap or your research focus
• Supports and guides research
• Can help you find a gap or your research focus

Audio: For your reader then, these are overviews literature reviews, excuse me, overviews of your chosen topic or field; that again demonstrates this depth of knowledge. This is what has been published on this topic thus far. It can even show a gap in research that you can then focus on. Like, what's an opportunity for furthering research there.

For yourself, it supports and guides the research. It can promote analysis and critical reading. There's a really strong analysis or synthesis part of a literature review. And lastly, it can help you find a gap in the literature that you can focus on. Everyone is looking for this gap in the literature that they can then use their study to fill and so this again can be something that helps you do that, the literature review.

Examination of all the scholarship on a particular topic or field written in narrative form via synthesis .

• Not summary or report
• Not just research that agrees
• Not a list of annotations or organized alphabetically or chronologically
• Not just summary or analysis

Audio: So, again, the purpose of a literature review to break this down a little bit farther is an examination of all of the scholarship on a particular topic or field written in narrative form via synthesis. There's a lot going on there, so were going to unpack this a little bit more.

It's an examination. It's not a summary or a report. You are not just regurgitating what a source says. You are not just reporting about this source. You are examining it. So, what's implied is that you will be working with this source and looking at some of the elements within a source and comparing it to other sources that way. So, it's not just a summary.

It's going to be all the resources within a certain narrowed topic area. Not all research is going to agree. You’re going to have those different voices at the dinner table. One scholar might not agree with another. So, you will highlight where they differ and how that disagreement comes about and what they are disagreeing about.

A topic will be a focus or a narrowed topic. You don't want this to be too broad. If you think about a topic like climate change, if you go into academic search premiere or another database to search for a different journal articles and type in climate change, you’re going to get thousands upon thousands of published articles. So, you need to focus that down so you are really narrowing your topic to focus on a specific conversation within that large umbrella topic area.

It's a narrative, so it's not a list of annotation. Or organized alphabetically or chronologically. You are putting it into writing could be another way to say that it's a narrative. You are not just listing or bulleting; you are bringing these together in paragraph form.

And, lastly, it is not just summary or analysis it’s synthesis, which is a kind of a big word that we use a lot here, synthesis, really the way I think of it is bringing two distinct things together to make a new whole. We’re going to talk about this in another slide. Is synthesis is putting two things together to create something new.

Visual: Slide changes to the following: Literature Review: Organization

Annotated bibliography = Organized by sources

Literature review = Organized by theme

Literature reviews are about synthesis

Audio: Here's our difference again. Annotated bibliography organized by sources. Literature review is not organized by sources; it's organized by themes. Right? So, if you are crafting a literature review, logistically speaking each one of your paragraphs in a literature review should contain more than one source. Part of synthesis is putting these sources in conversation with one another. Right? So, it's kind of hard to have a conversation alone (laughing). So, in a literature review each paragraph should cover a theme that multiple sources approach. And I’m going to explain that a little bit further as well. But again, don't organize your literature review by source; organize it by theme.

What is synthesis ?

• Identifying patterns among sources
• Analyzing strengths/weaknesses of the sources or field
• Comparing and contrasting the authors’ findings
• Interpreting what is known in your field and what is missing

Adding to the conversation

…Although Benson (2015) suggested technical innovations make providing health care easier, Campbell et al. (2014) noted that technology is only helpful if hospital staff are adequately trained on the new system. Thus, adequately training hospital staff is essential to successfully implementing new technology….

Audio: And, again, this brings in the synthesis piece which we will talk about right here. Synthesis. As I mention, bringing two different things together to make a new whole. The example that I like to give here is with chemistry. Synthesizing chemicals. You are taking two chemicals that are completely distinct from one another, they are different, and when you combine them, you’re creating something new. It's not just these two chemicals together now, it is something completely different. It's a new chemical. That is kind of how synthesis works in writing as well.

You’re going to identify patterns among sources. So, I have five sources that all talk about making a grill cheese sandwich. Two of these sources have the same methodology. They say to make a grill cheese sandwich in the same way. This is a theme or pattern within these sources. It would be appropriate then to discuss these two sources together and how they are subtly different in making a grill cheese sandwich.

Your analyzing strengths and weaknesses of a source or field. Comparing and contrasting an authors' findings. As you research in a topic area not every source is going to agree with each other. You will have authors that sometimes very distinctly or drastically disagree with each other. So again, you want to include all of the voices at that dinner party. You want to bring everyone's voice in and give them some time to express their views and relate that to the other views at the table.

You’re going to be interpreting what is known in your field and what is missing. And here's an example of this source synthesis idea. (Reading) Although Benson suggested technical innovations make providing health care easier, Campbell et al. (2014) noted that technology is only helpful if hospital staff are adequately trained on the new system. So, these are the two sources. We have two bits of information here. Benson says this and if the other side of the dinner table Campbell et al., says this, we’re bringing these two ideas together to make a new idea. That's the bolded portion on the slide. Thus, adequately training hospital staff is essential to successfully implement new technology. So, we say Benson says that new technology is makes giving healthcare, makes it easier to provide healthcare. Campbell et al, says it's important that all staff are trained properly on anything. To bring these together it's important to train hospital staff on new technology. It's two pieces that together yield this new point. Okay.

For those of you maybe feel confused or intimidated at this point, synthesis is a pre ‑‑ it's a high order scholarly or intellectual activity. It's something that needs to be practiced. It's a skill that needs to be developed. So, if you are not seeing how sources fit together right away, that's totally fine. You are going to be working with these sources more and these kinds of things will become more clear to you as you research more and deal with sources more. For those starting out, don't be intimidated. You will get it. Synthesis is a muscle that needs to be flexed it’s something that can be practiced and improved upon, so don't get discouraged is what I'm saying.

Yeah. This bit of synthesis adds to this conversation.

…After Kroll (2016) suggested that streamlining workflow using technology would allow for more time with patients, Macijewski (2017) noted that technology is only able to save time when hospital hardware is kept updated.

Is this a strong or weak example of synthesis?

Audio: Okay. We have our first chat here. And essentially, I’ve got a bit of a source, an excerpt from a literature review here. I'm looking for you to in this chat box speak about the strengths or weaknesses of this example, how well or lack thereof maybe are these; is synthesis being brought into this example. I'll give you a couple of minutes to do this. Again, put your answers in the chat box.

[silence as students respond]

Alright for the sake of time here, I’m going to move along. Let’s take a look at this. After Kroll 2017 suggested streamlining workflow using technology allowed for more time with patients... Macjewski (2017) noted that technology is only able to save time when hospital hardware is kept updated. Yeah, this is a, I would say this is an example of weak synthesis or a lack of synthesis at all. I see a couple of you kind of agreed with me in the chat box. I like how one student said it's a weak synthesis and the next student said no synthesis at all (laughing). It’s a little less diplomatic. But you are right, there's no synthesis here. What this is doing is presenting Kroll's idea and then it’s presenting Macijewski’s ideas. These are two separate things. Two voices in the conversation. But what this is forgetting that synthesis piece. Right? Is bringing these two things together. Given that these two ideas are both valid, what does that leave us with. Combining these, how do we make that whole. Here's an example of how that could look.

…After Kroll (2016) suggested that streamlining workflow using technology would allow for more time with patients, Macijewski (2017) noted that technology is only able to save time when hospital hardware is kept updated. Thus, hospitals must invest both in software and IT departments to support and update technology to be effective.

Audio: Again, we have Krolls idea here, we have Macijewski’s idea there. The synthesis that would make this a strong synthesis (laughing), the sentence that would make this a strong synthesis is highlighted in bold here. (Reading) Thus, hospitals must invest both in software and IT departments to support and update technology to be effective.

Yes, so this is bringing these together. Kroll saying technology could streamline this and make for more time with patients. Macijewski is saying the hardware needs to be up‑to‑date. Putting these two things together, hospitals need to make sure the software and the IT departments are supported for technology to be effective. Right? That's the new idea that we have created here.

Kroll isn’t talking about hardware systems within technology. Kroll is talking about how hardware could affect the delivery of services to a patient. Combining these two you have this new thing, new elements.

• Unique organization
• Talk about multiple authors in sections and paragraphs
• Allow authors to “talk to each other”
• Creates narrative form
• Limits organization
• Limits a paragraph to one source
• Doesn’t allow synthesis of sources
• Creates summary or book report feel

Audio: I'll move on. Some kind of do's and don'ts of a literature review and the organization. Do organize this by theme. Says a Unique organization. So, we have a link there can help you with this. You want to talk about multiple authors in the same section and paragraph. Absolutely. You want to allow the authors to talk to each other, to voice their specific ideas. Sure. And you want to create this kind of narrative, this paragraph displaying these authors' ideas.

When you don't do that, when you don't organize this by theme, when you only organize this by author, there's some pretty negative outcomes in terms of the effectiveness of that literature review. This limits your objection. This limit paragraphs to one source. You can only talk about one source at a time. That's not putting them in conversation with one another. Doesn't allow for synthesis of sources. Yeah, you can't create a new whole if you only have one thing. You just have the one thing (laughing). So yeah, that makes it ineffective also. And if you organize this by author, it just creates a summary or book report feel to it.  When really, we need this conversational piece and synthesis of these sources for this to be a true and effective literature review.

Visual: Slide changes to the following: Literature Review: Writing Tips

Use Paragraphs

No required or prescribed headings

Audio: Some general writing tips. Use paragraphs. You are not required or prescribed to use headings here. But as you can see this can be something that can be useful to use headings. You are not required, but it can be useful.

Use headings and comparative terms to direct the reader and organize the literature review

Cue your reader to organization and changing topics

Note subtopics of themes

Comparative Terms

Demonstrate where authors agree or disagree

Highlight your interpretation of the authors’ findings

Audio: A heading can cue a reader to an organization or changing of a topic. You can also use headings to explore subtopics of certain themes. Headings I don’t think are a bad idea within a literature review at all. So, yeah, if it helps you organize your thoughts that way, I would say go for it. This bit on the slide about comparative terms is really important also. The idea here being, and I know it sounds kind of silly, but words matter. Words have meanings, specific meanings, so you need to use a language that shows an accurate relationship between these sources. You want to demonstrate where authors agree and where authors disagree.

So, to give you an example how this could sound, you might use the word similarly to show how one author agrees with another. You might use the phrase on the contrary or conversely to show where one author disagrees with another.

Again, my point here being be careful about the language you use in combining and synthesizing sources, because it does have specific meanings. And if sources disagree, saying something like similarly would kind of be confusing to the reader. So, again, be cognizant of the terms that you are using in comparing these sources. Some mean they are agreeing, some mean they are conceding the point. Some mean that they are flat out disagreeing with another source. So be cognizant and aware of the comparative terms that you are using.

Organization

Note themes & patterns as you read

Use a matrix

Use a software program (like Zotero )

Develop an outline

Stay flexible as research develops

Use general good scholarly writing guidelines:

Effective Paraphrasing

Transitions

Literature Reviews: 5-Part Blog Series

Audio: Some tips here for creating a literature review. In terms of the organization, note the themes and patterns as you read. This is the annotation piece. If you look back at your annotated bibliography you’d say, okay, these three sources and their source summaries have all discussed this one idea, this one narrow idea. That's a theme that can be noted. Use the matrix, the library offers, a resource called the literature matrix, which can really be helpful in organizing your ideas as you compile sources. What this is, is it’s essentially an excel spreadsheet that asks you break down sources by different attributes. Things like sample size, like methodology, theoretical framework that sources are using. There's a link here that’ll get you to that matrix I would highly recommend that, I think it’s a really good resource that Walden provides.

Beyond Walden, is a program called Zotero. Which I’ve heard a lot of students at residency say is really useful, I think it has some added features that can be useful, so if that's something that interests you, go ahead and take a look at that and seek that out.  Developing an outline is important because then you’re taking those themes and you’re saying well I'm going to do one paragraph about this theme and one paragraph about that theme. So that can be useful in reviewing your literature as well. Also, you want to stay flexible as your research develope. This is just strong advice for research in general. Be open to the sources that you find and don't discard a source because you maybe disagree or it doesn't agree with some of your other sources.

In terms of resources, use general good scholarly writing guidelines. Things like Synthesis, effective paragraphing, paragraphs. Transitions are really useful in literature reviews. We have another resource here, literature reviews five-part blog series. That can be a good resource for you if you are compiling a literature review. Again, as with everything with writing, it's about finding what works for you. So, yeah, if you find a matrix or Zotero useful, by all means use that. Find a resource that works well for you is my point here.

Visual: Slide changes to the following: Literature Review: Example Headings

• Introduction
• Historical Context of Continuing Education
• The Need for Continuing Professional Educations in the Human Services
• Professionals’ Views of Continuing Education
• Continuing Education in the Funeral Profession
• Issues Regarding Mandatory versus Voluntary Continuing Education
• Advantages and Disadvantages of Mandatory versus Voluntary Continuing Education
• Formal and Informal Continuing Education
• Differing Methodologies

Audio: Here's is what an outline for a literature review could like look. These are some, potentially examples headings you could use. Introduction, paragraph. Then this author is going to talk about strategy. How different sources approach strategy. Historical context and continuing education. You get it. These are the different themes this author would have identified in the research. Then breaking it down. They’re going to talk about instances where the research they have gathered addresses the specific themes. And how maybe they agree, how maybe they disagree. Again, this is an example outline you can use, that gives you an idea how a literature review can be broken apart.

Visual: Slide changes to the following: Literature Review: Example Paragraph

As Stragalas (2016) argued, sharing specific details about the change will help to eliminate any difficulties. Steele-Johnson et al. (2015) echoed these sentiments when they reported that revealing all of the details about a change process can help those involved better understand and support the change. Steele-Johnson et al. also asserted that a high level of transparency during the change can help those involved prepare for and welcome the change. Similarly, Nahata et al. (2011) showed that transparency through excessive communication can allow for a wider range of acceptance of the change.

What are the strengths and weaknesses of this paragraph?

Audio: In the interest of time, I think I’m going to burn this second chat because I want to leave a little bit of time for questions. But by all means go back in and take a look at that if you downloaded these slides.

Audio: To recap, annotated bibliographies you really focus on an individual author and a source. You have your reference entry and your annotation. All of those refer to one specific source. This is a research tool that's meant to help you compile your research and see maybe how that research fits together. But it's really meant to see, compile research, and see what individual sources are doing, how are they approaching this topic? What did they find, how could they have done that better, how is this useful to me?

In a literature review, from that annotated bibliography, from the research you compiled you need to identify themes and patterns and reorganize that information around those themes or patterns. Under the theme of X, these three authors talk about that and they approach it in a different way. So that paragraph would unpack these three authors view views and some synthesis at the end, that when combined what these things say together, what is important here. That type of thing.

Here’s a resource on annotated bibliographies and here’s a few resources on a literature review. Both are master levels and doctoral level resource there.

Audio : Okay. With that then, I'll ask you again, Claire, any questions you would like me to talk through before we adjourn this webinar?

Claire: Thanks, Michael. I did have a good one which was: Do you recommend working on an annotated bibliography and a literature review at the same time? Or should one or the other potentially come first?

Michael: That is a good one. That's a good question. Well, first and foremost I would point towards this individual thing for different people. Right? If it works well for you to work on them side‑by‑side, I guess I can see a situation in which that might be useful. For me, in my opinion, I think you should do the annotated bibliography first before you do a literature review. Here's why. The literature review, again, it’s really important that you identify these themes and patterns within the research that you have collected. That identifying these themes and patterns informs how your literature review will be ordered and set up and how that synthesis is brought in. So, before you can do that you need to identify these themes. I think that the annotated bibliography as a tool can be really useful in looking at different sources in identifying those themes. I would say, personally, that you do the annotated bibliography before the literature review.

On a broader note, once again it's really about finding what works for you. So, if that's works for you to do them at the same time and to add to individual paragraphs separately, then go for that. That's your method. That's your process. But I would say do the annotated bibliography before the literature review.

Claire: Great. Thanks so much, Michael. I think that's all the questions we have for today. So, thank you for presenting. If you do have questions you can email us at [email protected] or again visit us during our live chat hours. I know that some of the links were not active during this presentation. Adobe Connect has been really finicky with us lately about doing some weird things with links when we transfer it to the presentation mode, but all the links should be just fine in the actual slides. So, if you want to download the slides, you can go to the pod at the bottom it’s right next to Michaels picture there and click slides lit review and annotated bibliography basics.

If you were looking for any of the links that were not functional during this presentation, they will all be active and correct in that slide show itself. I also want it have a quick plug for additional webinars. We do have some recommendations here. You can review them in our archive or check out ones that are coming up in our webinar schedule. And we are happy to review our next literature review as long as it's not for your dissertation itself. If it's for your course work assignments, those are great things to send into the Writing Center. We are here to support you that way as well.

Thank you all for a great presentation. Have a good rest of your day.

Literature Reviews

• General overview of Literature Reviews
• What should a Literature Review include?
• Examples of Literature Reviews
• Research - Getting Started

What is a literature review?

A literature review is an essential element of any proposal and academic article; it lays the foundation of your study while also giving readers an insight into the topic of your paper.

Why is it important for papers and proposals to have?

Well, a literature review is essential because it summarizes everything the reader needs to know to understand your paper, from the background to the importance of your study.

Here are a few other things literature reviews provide that elevate the validity of your paper:

• Discover relationships between ideas or studies
• Identify critical gaps in the research and ask further questions
• Explain significance of your research
• Critically review theory or methodology
• Familiarize yourself with current knowledge in the subject area
• Provide an overview of the research already performed in the subject area

Literature reviews help researchers and scholars justify, explain, and support their papers argument through:

• Giving a new interpretation of old material or combine new with old interpretations
• Tracing the intellectual progression of the field, including major debates,
• Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
• Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date

Given this, the key elements of a literature review are to:

• Place each work in the context of its contribution to understanding the research problem being studied
• Describe the relationship of each work to the others under consideration
• Identify new ways to interpret prior research
• Reveal any gaps that exist in the literature
• Resolve conflicts amongst seemingly contradictory previous studies
• Identify areas of prior scholarship to prevent duplication of effort
• Point the way in fulfilling a need for additional research
• Locate your own research within the context of existing literature

When and where do you use a literature review?

Literature reviews are the transition from the introduction of your paper to the methodology section, it is the only place where a literature review can make sense while maintaining the flow of the paper or proposal. 

• Introductions go over the paper's purpose as well as the concept of your project, introducing the reader to the stance you plan on taking. 
• A methodology focuses solely on the design of your project and how you plan to or have gone about your study.

Literature reviews are a combo of those two aspects, since they discuss relevant articles to help justify your paper's purpose, but usually by using the methodologies of other papers to do so. For your paper to flow well, a literature review needs to happen right after the introduction and before your paper's methodology.

Common Myths about Literature Reviews

You have to read everything related to the topic.

It is a common misconception among those writing a literature review for the first time that you must have read everything available on the theme. In reality, you have to pick the most relevant sources about your topic and only focus on them. 

You must include all the data you have read.

While it is easy to believe that you must summarize all the information available on a particular topic in your paper's literature review section, you only need to focus on the relevant articles again. And how the data from the articles help support and explain the purpose of your project and the methodology design. 

All the sources must be read till the end to be  understood.

Another widely believed myth is that you have to read a source from top to bottom to understand it. But this is not the truth here. If the only aspect of an article that supports your project idea is the methodology or the results, then only read those sections. You only need to focus on what aspects of the article you are reading will help support and explain your research project to others. Literature reviews are quick summaries of the relevant literature that is already out there. Whether it's to help explain why you went with a specific research design or to help show that your project will bridge a gap in the literature. You don't need to know or include everything in a literature review, just the relevant aspects that will support your project. 

Bibliographies and Literature reviews are the same.

A bibliography is not the same as a literature review. While a literature review discusses how you conducted your research and how your work fits into the overall body of established research in your field, an annotated bibliography simply explains how each source you used is relevant to your work.

Literature Review vs. Bibliography

• Literature Review
• Bibliography

 A literature review, similar to a bibliography, will consist of a summary of key sources and articles. Unlike a bibliography, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. 

Types of Literature Reviews

Argumentative Review This form examines literature selectively to support or refute an argument, deeply imbedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research (educational reform; immigration control), argumentative approaches to analyzing the literature can be a legitimate and essential form of discourse. 

Historical Review Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period, often starting with the first time an issue, concept, theory, or phenomenon emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.

Methodological Review A review not only focuses on what someone said in their findings, but how they came to their conclusions, which is their analysis method. Reviewing methods of analysis provides a framework of understanding at different levels [i.e., those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues you should be aware of and consider as you study.

Theoretical Review The main goal of a theoretical literature review is to provide an overview of the theoretical foundations, theories, and concepts related to your research. It might discuss theories definitions, models, or key concepts; it might argue in favor of a specific theoretical approach, or combine more than one theoretical concept to create the framework for your own research.

There are more types of literature reviews one can apply to their paper, but these are the most common ones used in research papers and proposals.

A bibliography is the list of sources a work’s author used to create the work. It accompanies just about every type of academic writing, like essays, research papers, and reports. You might also find a brief, less formal bibliography at the end of a journalistic piece, presentation, or video when the author feels it’s necessary to cite their sources. In nearly all academic instances, a bibliography is required. Not including a bibliography (or including an incomplete, incorrect, or falsified bibliography) can be considered an act of plagiarism, which can lead to a failing grade, being dropped from your course or program, and even being suspended or expelled from your school. 

Types of Bibliographies

Analytical bibliography

An analytical bibliography documents a work’s journey from manuscript to published book or article. This type of bibliography includes the physical characteristics of each cited source, like each work’s number of pages, type of binding used, and illustrations. 

Annotated bibliography

An annotated bibliography is a bibliography that includes annotations, which are short notes explaining why the author chose each of the sources. Generally a few sentences long, these notes might summarize or reflect on the source. 

Enumerative bibliography

An enumerative bibliography is the most basic type of bibliography. It’s a list of sources used to conduct research, often ordered according to specific characteristics, like alphabetically by authors’ last names or grouped according to topic or language. 

There are more types of bibliographies one can apply to their paper, but these are the most common ones used in research papers and proposals.

Frequently asked questions

What is the difference between a literature review and an annotated bibliography.

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .  

Frequently asked questions: Dissertation

Dissertation word counts vary widely across different fields, institutions, and levels of education:

• An undergraduate dissertation is typically 8,000–15,000 words
• A master’s dissertation is typically 12,000–50,000 words
• A PhD thesis is typically book-length: 70,000–100,000 words

However, none of these are strict guidelines – your word count may be lower or higher than the numbers stated here. Always check the guidelines provided by your university to determine how long your own dissertation should be.

A dissertation prospectus or proposal describes what or who you plan to research for your dissertation. It delves into why, when, where, and how you will do your research, as well as helps you choose a type of research to pursue. You should also determine whether you plan to pursue qualitative or quantitative methods and what your research design will look like.

It should outline all of the decisions you have taken about your project, from your dissertation topic to your hypotheses and research objectives , ready to be approved by your supervisor or committee.

Note that some departments require a defense component, where you present your prospectus to your committee orally.

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

• Plan to attend graduate school soon
• Have a particular topic you’d like to study more in-depth
• Are considering a career in research
• Would like a capstone experience to tie up your academic experience

The conclusion of your thesis or dissertation should include the following:

• A restatement of your research question
• A summary of your key arguments and/or results
• A short discussion of the implications of your research

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

For a stronger dissertation conclusion , avoid including:

• Important evidence or analysis that wasn’t mentioned in the discussion section and results section
• Generic concluding phrases (e.g. “In conclusion …”)
• Weak statements that undermine your argument (e.g., “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

While it may be tempting to present new arguments or evidence in your thesis or disseration conclusion , especially if you have a particularly striking argument you’d like to finish your analysis with, you shouldn’t. Theses and dissertations follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the discussion section and results section .) The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

A theoretical framework can sometimes be integrated into a  literature review chapter , but it can also be included as its own chapter or section in your dissertation . As a rule of thumb, if your research involves dealing with a lot of complex theories, it’s a good idea to include a separate theoretical framework chapter.

A literature review and a theoretical framework are not the same thing and cannot be used interchangeably. While a theoretical framework describes the theoretical underpinnings of your work, a literature review critically evaluates existing research relating to your topic. You’ll likely need both in your dissertation .

While a theoretical framework describes the theoretical underpinnings of your work based on existing research, a conceptual framework allows you to draw your own conclusions, mapping out the variables you may use in your study and the interplay between them.

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

In most styles, the title page is used purely to provide information and doesn’t include any images. Ask your supervisor if you are allowed to include an image on the title page before doing so. If you do decide to include one, make sure to check whether you need permission from the creator of the image.

Include a note directly beneath the image acknowledging where it comes from, beginning with the word “ Note .” (italicized and followed by a period). Include a citation and copyright attribution . Don’t title, number, or label the image as a figure , since it doesn’t appear in your main text.

Definitional terms often fall into the category of common knowledge , meaning that they don’t necessarily have to be cited. This guidance can apply to your thesis or dissertation glossary as well.

However, if you’d prefer to cite your sources , you can follow guidance for citing dictionary entries in MLA or APA style for your glossary.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, an index is a list of the contents of your work organized by page number.

The title page of your thesis or dissertation goes first, before all other content or lists that you may choose to include.

The title page of your thesis or dissertation should include your name, department, institution, degree program, and submission date.

Glossaries are not mandatory, but if you use a lot of technical or field-specific terms, it may improve readability to add one to your thesis or dissertation. Your educational institution may also require them, so be sure to check their specific guidelines.

A glossary or “glossary of terms” is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. Your glossary only needs to include terms that your reader may not be familiar with, and is intended to enhance their understanding of your work.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, dictionaries are more general collections of words.

An abbreviation is a shortened version of an existing word, such as Dr. for Doctor. In contrast, an acronym uses the first letter of each word to create a wholly new word, such as UNESCO (an acronym for the United Nations Educational, Scientific and Cultural Organization).

As a rule of thumb, write the explanation in full the first time you use an acronym or abbreviation. You can then proceed with the shortened version. However, if the abbreviation is very common (like PC, USA, or DNA), then you can use the abbreviated version from the get-go.

Be sure to add each abbreviation in your list of abbreviations !

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

A list of abbreviations is a list of all the abbreviations that you used in your thesis or dissertation. It should appear at the beginning of your document, with items in alphabetical order, just after your table of contents .

Your list of tables and figures should go directly after your table of contents in your thesis or dissertation.

Lists of figures and tables are often not required, and aren’t particularly common. They specifically aren’t required for APA-Style, though you should be careful to follow their other guidelines for figures and tables .

If you have many figures and tables in your thesis or dissertation, include one may help you stay organized. Your educational institution may require them, so be sure to check their guidelines.

A list of figures and tables compiles all of the figures and tables that you used in your thesis or dissertation and displays them with the page number where they can be found.

The table of contents in a thesis or dissertation always goes between your abstract and your introduction .

You may acknowledge God in your dissertation acknowledgements , but be sure to follow academic convention by also thanking the members of academia, as well as family, colleagues, and friends who helped you.

In a thesis or dissertation, the discussion is an in-depth exploration of the results, going into detail about the meaning of your findings and citing relevant sources to put them in context.

The conclusion is more shorter and more general: it concisely answers your main research question and makes recommendations based on your overall findings.

In the discussion , you explore the meaning and relevance of your research results , explaining how they fit with existing research and theory. Discuss:

• Your  interpretations : what do the results tell us?
• The  implications : why do the results matter?
• The  limitation s : what can’t the results tell us?

The results chapter or section simply and objectively reports what you found, without speculating on why you found these results. The discussion interprets the meaning of the results, puts them in context, and explains why they matter.

In qualitative research , results and discussion are sometimes combined. But in quantitative research , it’s considered important to separate the objective results from your interpretation of them.

Results are usually written in the past tense , because they are describing the outcome of completed actions.

The results chapter of a thesis or dissertation presents your research results concisely and objectively.

In quantitative research , for each question or hypothesis , state:

• The type of analysis used
• Relevant results in the form of descriptive and inferential statistics
• Whether or not the alternative hypothesis was supported

In qualitative research , for each question or theme, describe:

• Recurring patterns
• Significant or representative individual responses
• Relevant quotations from the data

Don’t interpret or speculate in the results chapter.

To automatically insert a table of contents in Microsoft Word, follow these steps:

• Apply heading styles throughout the document.
• In the references section in the ribbon, locate the Table of Contents group.
• Click the arrow next to the Table of Contents icon and select Custom Table of Contents.
• Select which levels of headings you would like to include in the table of contents.

Make sure to update your table of contents if you move text or change headings. To update, simply right click and select Update Field.

All level 1 and 2 headings should be included in your table of contents . That means the titles of your chapters and the main sections within them.

The contents should also include all appendices and the lists of tables and figures, if applicable, as well as your reference list .

Do not include the acknowledgements or abstract in the table of contents.

The abstract appears on its own page in the thesis or dissertation , after the title page and acknowledgements but before the table of contents .

An abstract for a thesis or dissertation is usually around 200–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

In a thesis or dissertation, the acknowledgements should usually be no longer than one page. There is no minimum length.

The acknowledgements are generally included at the very beginning of your thesis , directly after the title page and before the abstract .

Yes, it’s important to thank your supervisor(s) in the acknowledgements section of your thesis or dissertation .

Even if you feel your supervisor did not contribute greatly to the final product, you must acknowledge them, if only for a very brief thank you. If you do not include your supervisor, it may be seen as a snub.

In the acknowledgements of your thesis or dissertation, you should first thank those who helped you academically or professionally, such as your supervisor, funders, and other academics.

Then you can include personal thanks to friends, family members, or anyone else who supported you during the process.

Annotated Bibliographies & Literature Reviews

Writing an annotated bibliography, why do we write literature reviews, what are scholarly journals & peer review.

• Strategic Searching
• Locating Sources Online & At Pace
• Citing Your Sources

How are annotated bibliographies and literature reviews related? 

Annotated bibliographies collect sources and present citations along with a summary and analysis that connects the information to your research question. In a literature review , the author synthesizes multiple sources together to present the major themes, arguments and theories around a topic. 

Therefore, an annotated bibliography can provide an opportunity to review and analyze individual sources before o rganizing them around common denominators found across sources. 

Creating an annotated bibliography: 

• Review your assignment to determine how your professor would like your annotated bibliography to look.
• Search ! The "Strategic Searching" and "Locating Sources Online & At Pace" pages on this guide for assistance in locating potential sources. 
• Create the citations for your sources. 
• Write a paragraph for each citation summarizing, analyzing and determining the relevance of that source to your paper.                                                                       Icon by freepik

Examples: 

• University of Wisconsin: Annotated Bibliographies Research Guide This Research Guide page walks through the step by step process of creating an annotated bibliography.
• Rasmussen College: Annotated Bibliography Research Guide Watch the video and see an example of an annotated bibliography.

Literature reviews serve a purpose in research by: 

• Showing the writer's understanding of their topic area including key concepts, terminology, theories and definitions
• Identifying what research has been done in that area
• Finding gaps in the research or current areas of interest to help the writer tweak their own research question, if needed
• Identifying main areas of agreement, disagreement or controversy within the topic area
• Convincing the reader that your research question is significant, important and interesting

You are writing a MAP to the scholarly conversation on your topic.

• Planning and Creating a Literature Review Video Tips for searching, analyzing, and organizing sources for your literature review.

For your Literature Review you will summarize, evaluate, and synthesize, existing scholarship related to your research question. This "scholarship" is found in academic, scholarly, peer-reviewed journals. These differ from magazines and articles written for the general public because scholarly journals are written for researchers and experts in the discipline area. 

Click the link below titled, "Anatomy of a Scholarly Journal Article" to view an  interactive journal article and review what each section means.

You may need a few peer reviewed sources for your literature review. But what does that mean?

Peer-reviewed and refereed publications  include articles that are read and approved by an editor and one or more experts in that field to confirm accuracy of information and the contribution of that information to the scholarly conversation.

What is a literature review?

• Either a complete piece of writing unto itself or a section of a larger piece of writing like a book or article
• A thorough and critical look at the information and perspectives that other experts and scholars have written about a specific topic
• A way to give historical perspective on an issue and show how other researchers have addressed a problem
• An analysis of sources based on your own perspective on the topic
• Based on the most pertinent and significant research conducted in the field, both new and old

• A descriptive list or collection of summaries of other research without synthesis or analysis
• An annotated bibliography
• A literary review (a brief, critical discussion about the merits and weaknesses of a literary work such as a play, novel or a book of poems)
• Exhaustive; the objective is not to list as many relevant books, articles, reports as possible
• To convey to your reader what knowledge and ideas have been established on a topic
• To explain what the strengths and weaknesses of that knowledge and those ideas might be
• To learn how others have defined and measured key concepts    
• To keep the writer/reader up to date with current developments and historical trends in a particular field or discipline
• To establish context for the argument explored in the rest of a paper
• To provide evidence that may be used to support your own findings
• To demonstrate your understanding and your ability to critically evaluate research in the field
• To suggest previously unused or underused methodologies, designs, and quantitative and qualitative strategies
• To identify gaps in previous studies and flawed methodologies and/or theoretical approaches in order to avoid replication of mistakes
• To help the researcher avoid repetition of earlier research
• To suggest unexplored populations
• To determine whether past studies agree or disagree and identify strengths and weaknesses on both sides of a controversy in the literature

• Choose a topic that is interesting to you; this makes the research and writing process more enjoyable and rewarding.
• For a literature review, you'll also want to make sure that the topic you choose is one that other researchers have explored before so that you'll be able to find plenty of relevant sources to review.

• Your research doesn't need to be exhaustive. Pay careful attention to bibliographies. Focus on the most frequently cited literature about your topic and literature from the best known scholars in your field. Ask yourself: "Does this source make a significant contribution to the understanding of my topic?"
• Reading other literature reviews from your field may help you get ideas for themes to look for in your research. You can usually find some of these through the library databases by adding literature review as a keyword in your search.
• Start with the most recent publications and work backwards. This way, you ensure you have the most current information, and it becomes easier to identify the most seminal earlier sources by reviewing the material that current researchers are citing.

The organization of your lit review should be determined based on what you'd like to highlight from your research. Here are a few suggestions:

• Chronology : Discuss literature in chronological order of its writing/publication to demonstrate a change in trends over time or to detail a history of controversy in the field or of developments in the understanding of your topic.  
• Theme: Group your sources by subject or theme to show the variety of angles from which your topic has been studied. This works well if, for example, your goal is to identify an angle or subtopic that has so far been overlooked by researchers.  
• Methodology: Grouping your sources by methodology (for example, dividing the literature into qualitative vs. quantitative studies or grouping sources according to the populations studied) is useful for illustrating an overlooked population, an unused or underused methodology, or a flawed experimental technique.

• Be selective. Highlight only the most important and relevant points from a source in your review.
• Use quotes sparingly. Short quotes can help to emphasize a point, but thorough analysis of language from each source is generally unnecessary in a literature review.
• Synthesize your sources. Your goal is not to make a list of summaries of each source but to show how the sources relate to one another and to your own work.
• Make sure that your own voice and perspective remains front and center. Don't rely too heavily on summary or paraphrasing. For each source, draw a conclusion about how it relates to your own work or to the other literature on your topic.
• Be objective. When you identify a disagreement in the literature, be sure to represent both sides. Don't exclude a source simply on the basis that it does not support your own research hypothesis.
• At the end of your lit review, make suggestions for future research. What subjects, populations, methodologies, or theoretical lenses warrant further exploration? What common flaws or biases did you identify that could be corrected in future studies?

• Double check that you've correctly cited each of the sources you've used in the citation style requested by your professor (APA, MLA, etc.) and that your lit review is formatted according to the guidelines for that style.

Your literature review should:

• Be focused on and organized around your topic.
• Synthesize your research into a summary of what is and is not known about your topic.
• Identify any gaps or areas of controversy in the literature related to your topic.
• Suggest questions that require further research.
• Have your voice and perspective at the forefront rather than merely summarizing others' work.

Literature Review vs. Annotated Bibliography

The purpose of a literature review is to provide an overview of existing academic literature on a specific topic and an evaluation of the strengths and weaknesses of the author’s arguments. You are summarizing what research is available on a certain topic and then drawing conclusions about the topic.

An annotated bibliography is a list of resources that you have gathered on a topic that includes an annotation following the reference.  Like a References list, annotated bibliographies gather all resources discovered in the research process in one document. Each citation in the bibliography is followed by an annotation, a summary of that source.

An annotated bibliography is different from a literature review because it serves a different purpose. Annotated bibliographies focus on sources gathered for a specific research project. A literature review attempts to take a comprehensive approach to evaluate all of the research available on a particular question or a topic to create the foundation for a research paper. This review is often incorporated at the beginning of a research paper in its own section but it may also form the thesis for the paper.

Or as the University of North Alabama puts it " An annotated bibliography examines each source based on its relationship to the topic; a literature review draws together multiple sources to examine where they agree or disagree ."

What is the difference between an Annotated Bibliography and a Literature Review?

Annotated Bibliography - an annotated bibliography is a list of citations with brief notes added below each citation summarizing the content of the article cited (the annotation) included. The annotation accompanying a citation may also contain a short evaluation of the article in addition to a summary. 

Literature Review  - a systematic review of the published material, or scholarly writings, on a specific topic or research question that can be part of a scholarly work or a stand-alone product. The primary goal is analysis - and not simply summarization - of these scholarly writings. This analysis serves to provide background information on your topic and detail the connection between those writings and your research question. 

Learn More - Annotated Bibliographies

Annotated bibliographies are:

• Brief - about 150 words or so
• Summarize and evaluate a source
• Are located under the citation in a bibliography or works cited list
• Are distinct from abstracts, which are mostly a condensed description of an article
• Are distinct from literature reviews.
• Purdue OWL's Annotated Bibliography Page Purdue's Online Writing Lab's page on annotated bibliographies has examples of from the major citation styles and more.

Learn More - Literature Reviews

A Literature Review will help you achieve the following:

• Provides background on research topic
• Guides you in detailing or focusing your own research question
• Provides a framework for research or future research - identifying major themes and concepts
• Offers insights on unexplored ideas related to a topic, gaps in the research
• Assists with avoiding repetition of earlier research
• Tests assumptions; may help counter preconceived ideas and remove unconscious bias
• Identifies points of disagreement, or potentially flawed methodology or theoretical approaches

Searching databases such as  Web of Science, Google Scholar,   and  Dissertations & Theses   is the way you are able to discover the research that has been done on any given subject.

There are many resources available to help you understand what a literature review is and how to write one. Here are a few:

Annotated Bibliography vs Literature Review

• By Prof M Lambert
• November 12, 2020

If you’re undertaking a research project or writing a thesis in the US, be it at undergraduate, postgraduate, or PhD level, you may be wondering what the difference between an annotated bibliography and a literature review is.

Both are important sections of a research paper and aim to give context to the sources cited around a particular research problem. A literature review places a stronger emphasis on the importance of the findings of a paper, whilst an annotated bibliography focuses on the quality, validity, and relevance of the source of information itself.

What is a Literature Review?

A literature review summarises the research findings of others in a specific topic (this can be from a range of publications including scholarly journal articles, textbooks, interviews, and magazines), critically appraises their work, and uses this information to develop the research project at hand. The purpose of this section is also to identify any gaps in knowledge that exist in the research topic and how your research project can help address them. The literature review also allows you to question the research carried out, for example: does one author’s argument conflict with another’s?, or are a particular author’s conclusions valid?

What is an Annotated Bibliography?

Firstly, a bibliography is the list of sources referred to in a body of work. You should be familiar with this for any essay you have written – think of the APA style references you normally include. This includes important information about the source such as the author name, document title, date of publication, and page number (if applicable). The exact information differs depending on the source type – for example, a scholarly journal article may require a DOI ( Digital Object Identifier ) to be included in the citation, whilst a website will require a URL. The bibliography has several uses, primarily it serves as a reference point for readers who wish to read further into the statements made in a body of work. It also allows readers to question statements and verify the information provided in the body of work.

An annotated bibliography is a list of sources used in your body of work, which includes a brief summary for each source. These summary annotations evaluate the sources of information with regards to their accuracy and quality and identify any potential reasons for bias. As with a standard bibliography, an annotated bibliography should present sources alphabetically in a list-style format. The source summaries are typically around 150 words, though this can vary depending on the nature of the source.

Annotated Bibliography vs Literature Review – What are the differences?

The literature review is presented in a more conversational tone (essay format), as it looks to relate the findings of the source to the research question under review. In comparison, the annotated bibliography is much more structured and factual. It may evaluate sources that only have an indirect relevance to the current project.

Another difference is the length. As mentioned earlier, the annotation summaries are around 150 words per source. The literature review, on the other hand, is typically somewhere between 6,000 – 12,000 words. This reinforces the fact that the annotated bibliography is a concise assessment of the source, whilst the literature review is a comprehensive appraisal of the current knowledge and contributions around a particular topic. For example, the annotated bibliography may comment on a research paper which conducted a similar study and note information such as the scale of the experiments, how they were conducted, and which parameters were controlled. In the literature review this same source of information may be discussed further: what were the limitations of this type of experiment, how does the methodology compare to other studies, do the findings support your argument, and was the scale big enough to draw valid conclusions.

Students preparing a dissertation or thesis should use their annotation summaries to help develop their literary review. This can be done by using the information provided in the bibliography as a reference point to help paint the bigger picture in the literature review.

This post explains the difference between the journal paper status of In Review and Under Review.

The scope of the study is defined at the start of the study. It is used by researchers to set the boundaries and limitations within which the research study will be performed.

The Literature Review

According to Hart (1998), “A literature review is an objective, thorough summary and critical analysis of the relevant available research and non-research literature on the topic being studied” (as cited in Cronin, Ryan & Coughlan 2008).

The Literature Review Process

• Selecting a review topic
• Searching the literature
• Gathering, reading and analyzing the literature
• Writing the review

Lit Review Process

Types of Literature Reviews

• Systematic literature review

Implemented in response to specific questions about clinical practice; designation of criteria for including/excluding literature is important part of this type of review.

Purpose : aims at producing an inclusive list of the entire literature on a topic; set apart the literature on a topic based on predefined criteria; assess and synthesize these sources

• Traditional or narrative review

Summarizes, synthesizes and discusses literature on chosen topic; selective with regard to sources included.

Purpose : to give a comprehensive overview of the literature in a chosen area; to identify gaps in existing research; to develop conceptual framework; to refine research topic/question

(Cronin et al. 2008, 38)

Questions your lit review should answer

• Why is this subject important?
• Who else thinks it is important?
• Who has worked on this subject before?
• Who has done something similar to what I am doing?
• What can be adapted to my own study?
• What are the gaps in the research?
• Who is going to use my material?
• What use will my project be?
• What will my contribution be?
• What specific question will I answer?
• What specific questions will my research not be able to address?

Description : 

An annotated bibliography is a list of citations such as books, articles, and documents (a bibliography) with a brief summary and/or evaluation (annotation) for each citation. The purpose of the annotation is to inform the reader of the relevance, accuracy, and quality of the sources cited. Unlike other types of reviews, annotated bibliographies do not have established standards. Your bibliography will be guided primarily by its purpose and instructor guidelines (for class assignments).

What to cover in an annotation:

• Main focus, purpose, or claim of the work
• The usefulness of the citation to your research topic or goal
• The reliability, trustworthiness and quality of the source
• * Always refer to the requirements of the assignment

The Process: 

• Creating an annotated bibliography involves a concise background explanation, succinct analysis and informed research. 
• Search and collect relevant citations
• Examine and review the articles
• These articles should include a variety of viewpoints, address disagreements and controversies around a research topic
• Cite the works using an appropriate citation style
• Write a brief annotation for each citation

Literature Review vs. Annotated Bibliography vs. Research Paper... What's the difference?

Literature Review

The purpose of a literature review is to provide an overview of existing academic literature on a specific topic and an evaluation of the strengths and weaknesses of the author’s arguments. You are summarizing what research is available on a certain topic and then drawing conclusions about the topic. To make gathering your research easier, be sure to start with a narrow/specific topic and then widen your topic if necessary.

A literature review is helpful when determining what research has already been discovered through academic research and what further research still needs to be done. Are there gaps? Are there opportunities for further research? What is missing from my collection of resources? Are more resources needed?

It is important to note that the conclusions described in the literature you gather may contradict each other completely or in part.  A literature review gives the researcher an overview and understanding of research findings to date on a particular topic or issue.

Annotated Bibliography

An annotated bibliography is a list of resources that you have gathered on a topic that includes an annotation following the reference.  Like a References list, annotated bibliographies gather all resources discovered in the research process in one document. Each citation in the bibliography is followed by an annotation a 5-7 sentence paragraph consisting of a summary, an evaluation, and a reflection of that resource.

An annotated bibliography is different from a literature review because it serves a different purpose. Annotated bibliographies focus on sources gathered for a specific research project. A literature review attempts to take a comprehensive approach to evaluate all of the research available on a particular question or a topic to create the foundation for a research paper. 

For more information, please visit the annotated bibliography page of our APA guide.

Research Paper

A research paper presents a single argument/idea on a topic supported by research that you have gathered. Your own thoughts and opinions will be supported by research that you have gathered on your topic. The resources used in your research paper typically support the argument that you are making.

For more information on writing a research paper, check out our Writing guide .

Generally, either an annotated bibliography or a literature review are written first and set the framework for the final product: your research paper.

Writing Literature Reviews

What is a literature review.

"A literature review discusses published information in a particular subject area, and sometimes information in a particular subject area within a certain time period. A literature review can be just a simple summary of the sources, but it usually has an organizational pattern and combines both summary and synthesis. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information. It might give a new interpretation of old material or combine new with old interpretations. Or it might trace the intellectual progression of the field, including major debates. And depending on the situation, the literature review may evaluate the sources and advise the reader on the most pertinent or relevant." Source: The Writing Center at UNC-Chapel Hill. (2013).

Literature Reviews: Writing the Review

Outline of review sections.

Your Literature Review should not be a summary and evaluation of each article, one after the other. Your sources should be integrated together to create a narrative on your topic.

Consider the following ways to organize your review:

• By themes, variables, or issues
• By varying perspectives regarding a topic of controversy
• Chronologically, to show how the topic and research have developed over time

Use an outline to organize your sources and ideas in a logical sequence. Identify main points and subpoints, and consider the flow of your review. Outlines can be revised as your ideas develop. They help guide your readers through your ideas and show the hierarchy of your thoughts. What do your readers need to understand first? Where might certain studies fit most naturally? These are the kinds of questions that an outline can clarify.

An example outline for a Literature Review might look like this:

Introduction

• Background information on the topic & definitions
• Purpose of the literature review
• Scope and limitations of the review (what is included /excluded)
• Historical background 
• Overview of the existing research on the topic
• Principle question being asked
• Organization of the literature into categories or themes
• Evaluation of the strengths and weaknesses of each study
• Combining the findings from multiple sources to identify patterns and trends
• Insight into the relationship between your central topic and a larger area of study
• Development of a new research question or hypothesis
• Summary of the key points and findings in the literature
• Discussion of gaps in the existing knowledge
• Implications for future research

Strategies for Writing

Annotated bibliography.

An annotated bibliography collects short descriptions of each source in one place. After you have read each source carefully, set aside some time to write a brief summary. Your summary might be simply informative (e.g. identify the main argument/hypothesis, methods, major findings, and/or conclusions), or it might be evaluative (e.g. state why the source is interesting or useful for your review, or why it is not).

This method is more narrative than the Literature Matrix talked about on the Documenting Your Search page.

Taking the time to write short informative and/or evaluative summaries of your sources while you are researching can help you transition into the drafting stage later on. By making a record of your sources’ contents and your reactions to them, you make it less likely that you will need to go back and re-read many sources while drafting, and you might also start to gain a clearer idea of the overarching shape of your review.

READ EXTANT LIT REVIEWS CLOSELY

As you conduct your research, you will likely read many sources that model the same kind of literature review that you are researching and writing. While your original intent in reading those sources is likely to learn from the studies’ content (e.g. their results and discussion), it will benefit you to re-read these articles rhetorically.

Reading rhetorically means paying attention to how a text is written—how it has been structured, how it presents its claims and analyses, how it employs transitional words and phrases to move from one idea to the next. You might also pay attention to an author’s stylistic choices, like the use of first-person pronouns, active and passive voice, or technical terminology.

See  Finding Example Literature Reviews on the Developing a Research Question page for tips on finding reviews relevant to your topic.

MIND-MAPPING

Creating a mind-map is a form of brainstorming that lets you visualize how your ideas function and relate. Draw the diagram freehand or download software that lets you easily manipulate and group text, images, and shapes ( Coggle ,  FreeMind , MindMaple ).

Write down a central idea, then identify associated concepts, features, or questions around that idea. Make lines attaching various ideas, or arrows to signify directional relationships. Use different shapes, sizes, or colors to indicate commonalities, sequences, or relative importance.

This drafting technique allows you to generate ideas while thinking visually about how they function together. As you follow lines of thought, you can see which ideas can be connected, where certain pathways lead, and what the scope of your project might be. By drawing out a mind-map you may be able to see what elements of your review are underdeveloped and will benefit from more focused attention.

Avoiding Bias

Reporting bias.

This occurs when you are summarizing the literature in an unbalanced, inconsistent or distorted way . 

Ways to avoid:

• look for literature that supports multiple perspectives, viewpoints or theories 
• ask multiple people to review your writing for bias

Optical character recognition text, why are there errors in the text.

Optical Character Recognition, or OCR, is a process by which software reads a page image and translates it into a text file by recognising the shapes of the letters (The NINCH Guide to Good Practice in the Digital Representation and Management of Cultural Heritage Materials). We perform OCR on text-based resources, like newspapers, to enable full-text searching.

However, OCR is unlikely to be completely accurate. The level of accuracy depends on the print quality of the original issue, its condition at the time of reformatting (microfilming, digitization), the level of detail captured by scanners, and the quality of the OCR software. Scans of pages with poor quality paper, small or faded print, mixed fonts, multiple column layouts, or damage may result in low OCR accuracy.

The searchable text and titles in this collection have been automatically generated using OCR software. They have not been manually reviewed or corrected.

Please note that some historical materials may contain harmful content and/or descriptions. Learn how we're addressing it.

Evidence Review of the Adverse Effects of COVID-19 Vaccination and Intramuscular Vaccine Administration

Vaccines are a public health success story, as they have prevented or lessened the effects of many infectious diseases. To address concerns around potential vaccine injuries, the Health Resources and Services Administration (HRSA) administers the Vaccine Injury Compensation Program (VICP) and the Countermeasures Injury Compensation Program (CICP), which provide compensation to those who assert that they were injured by routine vaccines or medical countermeasures, respectively. The National Academies of Sciences, Engineering, and Medicine have contributed to the scientific basis for VICP compensation decisions for decades.

HRSA asked the National Academies to convene an expert committee to review the epidemiological, clinical, and biological evidence about the relationship between COVID-19 vaccines and specific adverse events, as well as intramuscular administration of vaccines and shoulder injuries. This report outlines the committee findings and conclusions.
