Subject guide

International Studies: how to write your thesis

This Subject Guide is designed to support students of International Studies with writing their BA thesis and research papers. This guide focuses on the research process, and suggests effective ways to: 1. find a topic and formulate a good research question; 2. search, find and evaluate literature; 3. search, find and organize primary sources; and 4. organize the research and writing process.

A. Getting Started & Staying Organized

Writing a thesis, or a larger research paper, can often be a challenge. It requires not only research skills, but also organizational skills to break down the process in smaller steps and make a realistic planning.

Sage Research Methods is a tool that helps you develop your research from the first to the last step .

B. Finding a good Topic

Leiden University’s library offers a number of tools to help you find a good research topic: Start your thesis .

Portland State University’s library, too, offers a good tool to help you get started: the DIY Library , and Ohio State University offers a handbook .

Three short videos that can help you get started are: Picking a topic IS research (by NC State); Choosing a Research Paper Topic (by University of Minnesota Libraries); How to Develop a Good Research Topic (by Kansas State Libraries).

C. Formulating a Research Question

The instruction page ‘ How to write a research question ’ of George Mason University’s Writing Center can form a good starting point, as well as this handbook .

You can also watch these short videos to help you get started: Developing a Research Question (by Steely Library); and Research Questions tutorial (by George Washington University Library).

D. Finding & Evaluating literature

Leiden University’s library offers help with finding and evaluating literature for your thesis or research paper.

You can find tutorials on searching for literature ; as well as tutorials on evaluating sources , or use this handbook .  

You can also ask for help by asking questions directly to library staff; or by a meeting with a subject librarian .

Two helpful short videos on finding literature include: One perfect source? (by NC State); and Tips & Tricks: Phrase Searching (by NC State).

E. Finding Primary Sources

The library provides access to a large number of digital resources, databases and archives . The Subject Guide for International Studies provides an overview of the various resources. 

Four examples of digital primary sources are  digital & digitised newspapers ; the Global Encyclopedia of Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ) History ; the Economist Intelligence Unit , which provides economic profiles and country reports; and the The Digital National Security Archive , which contains declassified CIA and US government documents.

You can gain an overview of the databases and e-resources offered through the library via this link .

F. Planning your Research Project

Students often struggle with making a realistic time-plan and then sticking with it. The following tools can help:

The Open University’s interactive website Time Management Skills portal helps you to develop your time management skills. See the following links for topics such as: - setting goals , - how to prepare a schedule and -tips for time management .

G. Help & Support

For questions about finding the right literature, you can approach the library, by asking questions directly to library staff; or by requesting a one-on-one meeting with a subject librarian .

For help with writing your thesis or research paper, you can also contact the International Studies Writing Lab .

For help with developing your Study skills & managing your studies (for example help with managing your time or coping with study stress), you can approach the Student Support Services for various workshops and courses .

If you are coping with more serious study-related or mental issues, you contact the study advisers or the university’s student psychologist , or visit the university’s website on well being .

Find a topic, formulate a research question, make a realistic time-plan

As a student you will have to do research assignments, write papers and hand in your final thesis before graduation. In order to succeed in this, you need to choose a good topic, formulate a researchable question, and make a realistic planning.

An effective tool for designing your research process in an effective way, is the SAGE Research Methods website . This website is user-friendly and helps you to break down your research process into smaller blocks. It also provides help with planning your research project.

Tips on how to choose a topic

• Get inspired: Take inspiration from your required readings for a course you like, browse the books in the Wijnhaven Library reading room , explore topics in peer-reviewed international studies journals , or have a look at other theses by former students . Ask yourself: which question has not yet been answered? What information seems to be missing? What can you add to the discussion?
• Brainstorm: Write down possible topic that comes to mind. These tutorials can help you with your brainstorm.
• P ick something you like : If you have little influence over your thesis topic, try and steer your assigned topic in the direction you would like to take it to. This can be a specific discipline (sociology, anthropology, politics, linguistics) era (historical approach) or method (surveys, data sets, newspapers, personal stories etc).
• Make sure you can make it into an academic treatise: A good number of students choose a thesis topic that aligns with their private interests. However, it can be a challenge to turn such topics into an academic treatise, because you may not have enough (1) relevant (2) academic and (3) accessible sources about the topic to base your argument on. Make sure that you choose a topic that you are passionate about, but that also has received scholarly interest, on which there is literature available, as well as other sources. If you start searching for sources in an early stage you can quickly determine whether your topic is in fact viable as a thesis topic or not.
• Mind the size of your topic: it is important to narrow down your topic to a manageable size. Too few sources means you may want to expand your topic a bit. On the other hand, having too many sources on your topic means you need to narrow your topic down further. This is one of the reasons why starting to search for sources early is an important step in pinpointing a research topic that is just the right size for you.
• Use the Sage Project Planner or other tutorials for defining a topic

Tips on how to formulate a good question

• Avoid questions that can be answered with ‘yes’ or ‘no’
• Have a voice: Ideally you already have a hypothesis, idea or point of view through which you can enter this topic. Often times you will adjust your view on the topic the more you learn about it.
• Formulate a ‘problem’ that you need to answer: Think about the big questions, such as ‘why’, ‘how’, ‘when’, and ‘who’. This will give you an open-ended question through which you can explore your topic.
• Avoid ‘Compare A to B and see what happens’ scenarios: There needs to be a formulation of a ‘problem’ and a point of view.
• Use these tutorials or the Sage project planner to develop a researchable question

Tips on how to meet your deadline

• Start with a general overview of the amount of time you have: When is your deadline? When can (and when should) you get started? How many hours can you realistically spend per week on this project?
• Write down the steps you need to take from start to end: Go through this research guide to get an idea of how much time you need for your research. Don’t forget about things that might not be included here, such as spell checks, format checks, printing and binding etc.
• You can use the Sage project planner to make a planning .
• Be realistic: A realistic planning will help you to set goals and avoid stress by impeding deadlines. Underestimating the amount of work needed to write a well-researched, well-written paper is the number one reason students experience a lot of overwhelm from the research process. Therefore, be realistic about the amount of work you can put in in a day.
• Write down your daily top 3: Write down three achievable things you want to have finished by the time you are done for the day and start with the most important thing.
• Don’t forget to take a break: It is important to put away what you wrote for a bit so you can revisit it later. Oftentimes, when you go back to your text at a later point, you see little inconsistencies that you overlooked earlier; or you have new insights to add to your argument.
• Time Management Skills: Planning your research is about much more than just prioritizing and setting goals. It is also about how you deal with distractions, procrastination, and what to do if you fall behind. Time management skills are essential skills not only for now, but also for when you find employment.

A. Finding literature is not like a trip to the supermarket

Some students approach the act of gathering information for their research as if they were taking a trip to the supermarket; they expect to be able to find exactly what they need within a certain set amount of time. Unlike a supermarket trip, however, searching for scholarly information is difficult, and you do not always get the results you want. This is mostly due to the fact that it is easy to (1) overestimate the quality and availability of the sources you need, and (2) underestimate the amount of time and skill needed to find these sources amidst the millions of sources out there.

In other words, some students expect to find ‘perfect sources’ for their thesis topic – meaning; academic sources that ‘tick all the right boxes’ of their thesis topic – fully downloadable, and found with little effort with just a few keywords and clicks. In reality, however, the ‘perfect source’ likely does not exist, many sources you need will not be available digitally, it will take quite some time and effort to find these sources, and you will have to pick up some new search skills along the way. This often causes students to experience the ‘search’ and ‘access’ phase as the most frustrating, unsatisfactory experience in the whole research experience.

Frustration, coupled with a lack of time, makes it tempting for students to turn to less trustworthy or relevant sources because they are more familiar (Google), or more easily available (full-text search only). This, however, leads to an unbalanced and incomplete list of sources. It is therefore important to think about how you search; are your expectations realistic? What are your pitfalls when pressed for time or when something does not work out immediately? How can you avoid them?

The good news is that you don’t need to find a ‘perfect source’, and this brief video shows you why : ‘Good research isn’t about finding the perfect article that makes all the connections for you, it’s about finding information that helps you form your ideas, and tying it together yourself to form a cohesive argument.’

If the perfect source already existed, there would not be a reason for you to write your thesis or paper. As a researcher, your assignment is to get to know the literature on a topic, identify what is missing, and add to the existing knowledge with our own writing. Sage Research Methods helps you to approach your research project in exactly this way.

Second, there are many ways the  library can help you get access to difficult-to-obtain sources and teach you how to search. Third, if you make a project plan early and manage your time, you should have enough time to search for the sources you need, thus avoiding a lot of stress and frustration.

B. First Step: Background Search

The best way to start your search is getting yourself more acquainted with the topic; you know some things about it, but there is a lot that you do not (yet) know. Background search can help you to identify important facts (dates, events, people, terminology) refine your topic (what aspect about this topic is it that truly interests you?), and give you additional information and tips on where to search (dictionaries, encyclopedias, databases). For your background search you can use Google, Wikipedia, your textbooks, bibliographies and encyclopedias .

At this stage of your research, important tools to start with are Google Scholar , which allows you to search and browse journal articles as well as the bibliographies that you can find in this Subject Guide for International Studies . The bibliographies are curated by a specialized staff and are more complete and systematic.

When doing background research you can start with a couple of keywords. You can use keywords from titles or abstracts. Specific keywords can narrow or broaden the amount of information you will find. Try out different (combinations of) keywords/synonyms to see what kind of information you get and which terms are useful. Learn more in these tutorials about keywords.

You can also use the so-called snowball-method to find literature on your topic: simply browse the bibliography at the end of a book or article that you found convincing to see if it contains other titles related to your topic.

C. Searching in the Library Catalogue

Try out different search terms when you start searching in the catalogue. The catalogue automatically searches for all of the entered search terms in one document unless you use OR. You can use NOT if you want specific words to be excluded. If you don’t know how to spell a word or it can be written in different ways, you can use the symbol # or ? (wom#n finds woman and women). When you have found a relevant item, you can also use the references or citations as new sources. It is not recommended to limit yourself to things only available in Leiden University by selecting ‘Leiden Collections’ instead of ‘All content’ in the search screen. See our catalogue tutorial .

D. Find Literature Elsewhere

Though Leiden University provides access to an extensive collection of literature related to International Studies, many more can be found elsewhere.

Recommended Library Catalogues

• Worldcat : is the biggest world-wide search engine for library holdings. You can use it to search information about books, but also to locate the nearest library (inside or outside the library) that holds a copy. If any book or journal you found is unavailable in Leiden, you can either visit the holding library (which is often free for Dutch University Students) or request the item through (International) Inter Library Loan .

Recommended Online Search Engines

• Google Scholar is Google’s search engine for scientific articles and academic books. It is recommended not to limit your search activities to Google, but it does offer a good starting point.

Recommended Bibliographies

• A great number of specialized, academically curated bibliographies on many topics and fields can be found through the Subject Guide for International Studies .

A. Digital and Paper Sources

Tips for accessing digital sources.

• If you have found a digital source in the catalogue that you wish to access from home you need to login via the library catalogue, using your ULCN credentials, and not via a publisher portal. You can also use the Get Access browser extension .
• If you come across a source in the catalogue that is listed as “Online Access” or “Open Access” but you cannot get access, click the ‘report a problem’ option within the record. 

Tips for accessing Paper sources

• You need a valid LU card for access in most buildings.
• Leiden University Libraries consists of several library locations. Depending on your research topic, you may need to access physical books from these different locations.

B. Not available in Leiden?

There are a number of ways in which you can get access to materials that are not available at Leiden University Libraries.

How to get access to materials not available in Leiden

• Look up the book or journal in Worldcat . If you enter your zip code, you can find the library nearest to you that has a copy, such as the Royal Library in the Hague or other University Libraries.
• The Royal Library in the Hague offers a 50% discount for students for a one-year membership. Leiden University Students can apply for a library card free of charge at all Dutch Universities.
• Request the item through Inter Library Loan (ILL ) or through  International ILL .
• Ask Leiden University to acquire the item : You can file a request for the library to purchase a book, access to a journal or database. All requests are considered by the relevant subject librarian, and a decision is made depending on collection policy, available budget and price of the item. Please keep in mind that, in case an item is purchased, it can take several weeks for the item to be shipped and processed.
• Contact your subject librarian . If the above measures did not help, reach out to your subject librarian. It is possible that they know different means and methods within their field of expertise to obtain access to the materials you need.

A. Why do I need to evaluate scholarly publications – wasn´t that evaluated already?

Students are required to be critical of all their sources, including the ones you find in the library catalogue, academic databases, and those quoted in other scholarly publications. In today’s world, publishing and sharing information has become accessible to all, which also has made it easier to publish misinformation.

Academic information, at least, has put up a number of hurdles to tackle misinformation and disinformation from spreading, such as peer review . However, aside from the fact that these measures are far from failsafe , journals, books and authors can certainly be biased or prejudiced while working within the academic framework. It is your job as a scholar to be critical of all sources you use – academic or not – and train yourself in recognizing credible sources and using them in a critical fashion.

B. Popular & Scholarly

At the beginning of your student career at Leiden University, you may sometimes miss the difference between scholarly information and popular sources, and why this difference is important.

Media like YouTube videos, blog posts, or magazine articles can be tempting to use in a paper, because they (1) mainly focus on being entertaining instead of being informative, (2) use clear and easy to understand language, and (3) due to algorithms, are likely to confirm your pre-existing worldview and ideas. The goal of a research project, however, is to approach a certain problem in an open way, and embark on a research as an open-ended process. For such a project, usage of scholarly publications is crucial.

One of the main differences between popular sources and scholarly sources is the scientific rigor that lies at the basis of an analysis and argument, and transparent presentation of the used methods and sources. These are part of the scholarly format of peer-reviewed and annotated texts. Illustrative of the importance of this format is the fact that an op-ed written by a professor is categorized as a popular source, while an article in a scientific journal by the same professor is categorized as a scholarly text.

It is especially tricky when opinions of the author are presented as ‘facts’ that seem correct due to being based on cherry-picked data. If you are not yet confident in discerning between scholarly and popular sources, we recommend you follow a couple of tutorials .

C. Evaluating information

It is important you ask yourself a number of questions while reading a source, such as: Who wrote the information, why did they publish it, is there an agenda and when/where was it published? All of this comes before you can think about the text itself. This follows a technique used by professional factcheckers, called lateral reading , where you first consider the container of the text, before you look at the text itself. 

The above is useful for information found both in print and online. For information found solely online there is an additional method, called the SIFT method . SIFT stands for Stop, Investigate the Source, Find trusted coverage, Trace claims, quotes, and media back to the original context. In many cases it will take about 30 seconds to quickly check whether for example a news report is true once you have trained yourself in the four moves of SIFT.

Take a look at these tutorials about evaluating information.

A. Reading and searching: two sides of the same coin

The most conventional method of discovering relevant authors and publications for your research is discovering them citations and references of other publications. We therefore recommend to make enough time to read your sources, and then do follow-up searches. When reading ask yourself: which authors are talking about my topic, what do they say, what books/articles did they write, which sources do they cite and how was the research conducted?

You may think that reading all the sources you find in order to do follow up search will take too long. However, in this part of the research process, you are only reading your sources to (1) confirm that they match your information need, (2) double-check that they are academic (3) not too old for your topic of choice, and (4) find references to other scholars and publication about your topic.

Tips on strategic reading

• Scan : Quickly go through a text by reading just the titles of chapters, abstracts of papers, paragraph titles, or the first sentence of a new paragraph, and the conclusion. This will help you determine whether or not you want to read the source more in detail, and which parts you can easily skip.
• Reading and Note making: You will have to read, process and remember information from a lot of different sources. To stay organized, it is important to make efficient notes while reading. Look here for a top five of critical reading techniques and a brief course on critical reading .
• Don’t forget to write down where your information comes from ! If you are not sure where the information comes from when you start writing, you are at risk of plagiarism. Tip: The quickest way to make a short note when you are reading is taking the last name of the author  + page. For example: Hall, p. 31. If you use multiple sources by the same author, add the publication year. (Hall, 2005, p. 31)
• For more information see the Critical Reading Techniques .

Rinse and Repeat

At this stage, you have found a good number of sources, read them, took notes, and likely found other publications authors and data that you have not found before. This marks the second round of searching for sources – look up that interesting looking book you found in a citation, find out what else the author of that book wrote, see if you can get it through Leiden University or other means, and... read! By repeating this cycle of read-search-access-read two or three times, you are very likely to find (1) the majority of relevant publications on your topic of choice, (2) the majority of authors writing about your topic of choice, and (3) a good overview of primary sources relating to your topic of choice. Only once you have followed this thorough and deliberate way of locating your sources are you ready to move forward.

B. Refine your topic

This is a good point in your research to revisit your topic and your research question. While reading you may have found that there is much more information available about your topic than you initially thought – or not enough. You may have found that your research question has already been dealt with in length by other scholars, while at the same time, another question that is even more interesting may have come to mind. Perhaps you would like to take your research into a whole different direction after doing some reading and follow up research? When you are refining your topic, allow yourself to be flexible. It is common to modify your topic during the research process.

Take some time to visit the checklist for your topic and research question again, and see if you need to make any chances. If you have already handed in your topic and research question to your supervisor, you should always inform them of any major changes you wish to make. Have a look at this overview of tips for refining your research topic .

In some cases, using primary sources for your research is optional, in other cases it is an obligatory part of your research. Students can use a variety of primary sources for their projects, depending on their topics. Different sources may require different research methodologies.

Central to all primary research projects is, however, that you systematically analyze a well-delineated corpus of sources. The delineation refers both to the source and the time-frame. For example, instead of analyzing how ‘the media’ reported on a topic, choose a specific media outlet (for example one newspaper) or set of media outlets (a well-delineated set of newspaper titles), and research the news reports over a specific time-frame (for example: how did the New York Times report on North Korea’s nuclear weapons program between 2010 and 2020). A similar systematic can be used when analyzing statistical data, CIA reports, the correspondence between Marx and Engels, etc.

Sage Research Methods provides a good overview of the most important primary source research methods , as well as examples and cases.

The library provides access to a large number of digital resources, databases and archives . The Subject Guide for International Studies provides an overview of the various resources.

A. Managing your research project

Once you have found, evaluated, and read all of your literature (for now) it is time to think about what you have read and to organize your findings. This can be a challenging phase in the research project. If you feel overwhelmed by the work you have to do, various actions may help: 1.) break down the project into smaller steps; 2.) make a time plan that enables you to find a good balance between reading, researching, writing, and free time; 3.) break down your thesis or paper into smaller blocks that you can separately work on.

Tools that can help you to break down your project into smaller parts and to manage time-planning are: the Sage project planner ; and the Open University’s Time Management Skills portal. See the following links for topics such as: setting goals , how to prepare a schedule> tips for time management .

For help with developing your study skills & managing your studies (for example help with managing your time or coping with study stress), you can approach the Student Support Services for various workshops and courses .

B. Synthesizing; Interrogating the literature

Your thesis or research paper needs to clearly relate to the existing literature on a topic: you need to show who you (dis)agree with and what you are adding to the existing body of knowledge. This means that you need to identify at least the following three points (1) common themes between sources, (2) points on which the sources/authors (direct or indirect) disagree and (3) gaps in the literature (what is missing?).

This does not mean that you should just give a number of summaries of articles. Instead, it is important to compare and contrast, broaden the argument and give your own thoughts and conclusions. For a more detailed explanation on synthesizing and integrating information, use one of the following sources:

• “Help…I’ve been asked to synthesize!”
• Simply Psychology – how to synthesize written information from multiple sources.

C. Footnotes, Citations and Citation Managers

For your thesis or research paper you are potentially going to refer to a large body of sources. Typing up all the footnotes by hand, and maintaining one consistent reference style is time-consuming. Therefore, it is highly recommended to use an electronic citation manager. Learning how to work with a reference manager is a new skill, but it will save you time in the long run – the more papers you write, the more time you save.

Mendeley, EndNote and Zotero are three of the main refence managers. You can learn more about these programmes on our page about reference managers.

• There are brief introductory videos on Mendeley , Endnote , and Zotero .

There are various citation methods. International Studies theses and papers are to use CMS as their citation style. The most important thing about using a citation style is consistency . Do not mix up the different styles and rules! If you are uncertain which style you should use for your paper or thesis, always consult with your supervisor. See these tutorials and books below that can help you get started with making your own citations below. 

Recommended Books:

• Cite Right : a quick guide to citation styles.
• Doing honest work in college: how to prepare citations, avoid plagiarism and achieve real academic success : deals with today’s issues, like citing podcasts or social media posts, using mobile devices during tests, and the pro-s and cos of reference managers.
• Cite them right : the essential referencing guide.

D. Writing the Report

For the actual writing of your thesis or research paper, structure is important in a double sense of the word. First of all, it is important to structure your thesis into smaller parts that you can write in subsequent order. Secondly, it is important to structure your working day and working week in such a way that you can find a productive balance between working on your thesis and doing other things.

Next to the Sage project planner , the website of the Australian National University can help you to design an effective structure for your thesis.

For structuring your working day and working week, you can take cue from the Open University’s Time Management Skills portal. See the following links for topics such as: setting goals , how to prepare a schedule and tips for time management .

Another helpful website is the Thesis Whisperer , which among other offers advice on How to become a literature searching Ninja , and on How to write 1000 words a day (and not go bat shit crazy) .

Library For questions about finding the right literature, you can approach the library, by asking questions directly to library staff; or by requesting a one-on-one meeting with a subject librarian . If you would like to suggest purchase requests, contact the subject librarian for International Studies, Nathaniël Linssen .

Writing Lab For help with writing your thesis or research paper, you can also contact the International Studies Writing Lab .

Workshops on Managing Time and Coping with Study Stress For help with developing your Study skills & managing your studies (for example help with managing your time or coping with study stress), you can approach the Student Support Services for various workshops and courses.

Study-related and Mental Support If you are coping with more serious study-related or mental issues, you contact the study advisers or the university’s student psychologist , or visit the university’s website .

How to Write a Literature Review | Guide, Examples, & Templates

Published on January 2, 2023 by Shona McCombes . Revised on September 11, 2023.

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 that you can later apply to your paper, thesis, or dissertation topic .

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 summarize sources—it analyzes, synthesizes , 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 thesis , dissertation , or research paper , you will likely 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 its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Here's why students love Scribbr's proofreading services

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 problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. 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 as 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 useful 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 also use boolean operators to help narrow down your search.

Make sure to 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.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

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?
• 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 use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

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 is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation 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.

To begin organizing your literature review’s argument and structure, be sure you 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 organizing the body of a literature review. 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 summarizing sources in order.

Try to analyze 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 organize 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.

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, you can follow these tips:

• 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 sentences to draw connections, comparisons and contrasts

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

When you’ve finished writing and revising your literature review, don’t forget to proofread thoroughly before submitting. Not a language expert? Check out Scribbr’s professional proofreading services !

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 thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

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

• To familiarize 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 thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

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 .

Please review this video: Getting Started with Literature Reviews tutorial  

What is a literature review?

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.

How is a literature review different from an academic research paper?

The main focus of an academic research paper is to develop a new argument, and a research paper will contain a literature review as one of its parts. In a research paper, you use the literature as a foundation and as support for a new insight that you contribute. The focus of a literature review, however, is to summarize and synthesize the arguments and ideas of others without adding new contributions.

How do I know when I can stop?

Literature reviews can be tricky because you don't want to stop before you've found everything relevant to your topic. There are a couple of guidelines for knowing when to stop looking for materials.

• Searched all relevant databases, using a variety of keywords and subject headings
• Mined article bibliographies for their cited references
• Looked in Google Scholar or Web of Science to see who has cited those articles
• Think of the assignment timeline. If you are writing your PhD thesis you can spend more time doing a comprehensive lit review than if you only have a few weeks until an assignment is due. At some point you need to stop.
• Government Information This is an in-house research guide that provides direction on finding government information in many formats, paper, microform, and online.
• Data and Statistics: International Guide to data and statistics specifically for international sources.
• Legal Research Guide to Legal Research, mostly United States.
• Economics Research Guide Guide to research resources in Economics.

I.  What is a Literature Review? The purpose of a review is to analyze critically a segment of a published body of knowledge through summary, classification, and comparison of prior research studies. It can be a simple summary of the sources, but it usually has an organizational pattern, combining both summary and synthesis.

• Review of the Literature (Wisconsin)
• Systematic Literature Review vs Narrative Reviews
• Get Lit: the Literature Review Candace Schaefer in the Texas A&M University Writing Center.

III.  What Major Steps and Basic Elements Literature Reviews Require?

• Overview of the subject, issue or theory under consideration, along with the objectives of literature review
• Perform a literature review, finding materials relevant to the subject being explored
• Division of works under review into categories (e.g. those in support of a particular position, those against, etc)
• Explanation of how each work is similar to and how it varies from the others
• Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research
• Write a Lit Review (UCSC)

IV.    Which Citation Tool Are You Going to Use to Manage the Literature Sources? Choose your citation tool before conducing your literature reviews.  There are a number of choices, including following software supported by the Libraries and the University:

• RefWorks Available at no cost to Texas A&M affiliates.
• EndNote Available for free through a campus-wide site license.

Cited Reference Searching

Cited references are the sources consulted in writing an article or a book, often referred to within the text of the work. A list of cited references may appear as Bibliographic Notes, Footnotes or Endnotes, References, List of Sources Cited or Consulted. In order for an article to be cited, it needs to have been published for a long enough period of time for another published article, citing it to appear.

These listings can be helpful in a number of ways:

• Finding an article on a relevant topic and accumulating similar helpful resources
• Following a specific idea or theory back to its first appearance in the literature
• Finding articles that build on a specific theory or the most recent article on a topic
• Identifying experts or leaders on a specific topic
• Documenting scholarly reputation and impact for tenure and promotion

The cited reference databases are efficient in pulling together many articles on a topic with their references and in identifying which articles on a topic have been cited most frequently.  They can also help identify the “top” journals in a field by impact factor, which may be useful for assessing them.

• Web of Science This link opens in a new window covers the world’s leading scholarly literature in the sciences, social sciences, arts, and humanities and examines proceedings of international conferences, symposia, seminars, colloquia, workshops, and conventions. It also includes cited references and citation mapping functions.

Searches can be done by:

• Title or Topic
•  Author or Editor – The Author Finder tool includes variations on an author’s name
• Journal or Publication Name
• Grant Name or Funding Agency
• Limited by year, Language, Document Type 

The citation of the article  will be retrieved with its references as well as the number of times cited and by whom.

You can refine your search results by subject area, useful when there is more than one author with the same name, or by document type.  You can see the number of articles in your set contributed by particular authors and institutions and can create a citation report to identify which articles in your results have been cited the most.

You can easily export your results to bibliographic software like EndNote or RefWorks.

Articles can be searched by:

• Abstract word or keyword
• Source or journal
• Author (by name or by affiliation)
• Limit by date or document type

The database allows accounts to be set up and can save search alerts and journals lists.  Scopus also provides journal analytics including data and graphs to illustrate the total citations, articles published, trend line and % not cited over time.  It has the ability to exclude self-citations.

Some points to remember

• Include only the most important points from each source -- you want to digest, not quote from, the sources.
• The value of the review for you audience will consist in a clear, well-organized synopsis of what has been found so far on your topic. 
• Avoid plagiarism in your lit review. Consult this UO Libraries tutorial on Academic Integrity if you need some guidance.

If you would like more pointers about how to approach your literature review, this this handout from The Writing Center at UNC-Chapel Hill  suggests several effective strategies.

Sage Research Methods

Dr. Eric Jensen, Professor of Sociology at the University of Warwick, and Dr. Charles Laurie, Director of Research at Verisk Maplecroft, explain how to write a literature review and why researchers need to do so.

The steps of how to write a literature review discussed in the video include the following:

• How Do You Conduct a Literature Review?
• How Do You Find and Organize Sources of Information?
• How Do You Assess These Sources of Information?
• How Do You Write up Your Findings?
• How Do You Identify Gaps in Literature?

Other sources for Writing Literature Reviews

• Owl Purdue - Writing a Literature Review Provides a general overview of how to write a literature review.

What's a Literature Review?

• Acquire a better understanding of the current state of knowledge in a particular discipline or field of study, providing context for a research project.
• Identify key concepts, theories, methodologies, and other findings related to their research topic, which helps researchers in build theoretical frameworks based on established theories and concepts.
• Identify gaps in a disciplinary area where there is a lack of research or conflicting findings, and highlight major questions that should be addressed in further literature.

Types of Literature Reviews

• Narrative literature reviews provide a general, qualitative summary of the literature. Narrative reviews focus on only a few studies that describe a topic of interest and are not systematic. Undergraduates writing research papers for the first time are usually assigned to write this type of review.
• Systematic reviews  follow a structured and rigorous methodology to systematically gather, analyze, and synthesize all relevant studies on a specific topic of literature. Systematic reviews use specific criteria to decide what literature to include in the review. Systematic reviews are primarily used in the medical and psychological literature.
• Meta-analyses  combine empirical statistical analysis research and data from multiple studies. The terms meta-analysis and systematic review are often used interchangeably.
• Scoping reviews map the literature in a broad sense to identify key themes and gaps. Unlike systematic reviews, which have a narrow focus, scoping reviews are broader in scope and explore a diversity of the available literature in a given field.

Resources for Locating Literature Reviews

Published literature reviews of all types are found in a variety of research databases. It is important to search different databases to locate relevant reviews. Regardless of the databases used, the following searches can be helpful:

• " literature review " OR " review of the literature " AND " your research topic/question/key terms "
• " systematic review " AND " your research topic/question/key terms "  
• " meta analysis " OR " meta-analysis " AND " your research topic/question/key terms "
• " scoping review " AND " your research topic/question/key terms "
• Annual Reviews The Annual Reviews series of publications provides literature review articles that analyze the most significant scholarly research published within the preceding year. These article-length reviews are authored by leading scholars and cover over 40 different subject disciplines in the social, behavioral, and hard sciences.
• JSTOR Started as a grant-funded project at the University of Michigan, JSTOR is now a  premier scholarly digital research database primarily for the humanities and social sciences. In addition to journal articles, users can access ebooks, book chapters, images, and primary source documents.  JSTOR contains the full text of more than 2,300 journals from 1,000 publishers, with publication dates ranging from 1665 to 2015 (for specific titles). Journals are available in more than 60 disciplines in the humanities, social sciences, sciences, and mathematics. Note:  The majority of journals in JSTOR have an embargo period or "Moving Wall" delay of 3 to 5 years. This means there is a gap in the availability of current issues of most JSTOR journals.
• The International Bibliography of the Social Sciences (IBSS) The International Bibliography of the Social Sciences (IBSS) is compiled by the British Library of Political and Economic Science at the London School of Economics. It provides access to scholarly literature in the social sciences, covering various disciplines, including sociology, political science, anthropology, economics, geography, and more. It includes over 3 million bibliographic references to journal articles, books, book reviews, and selected book chapters back to 1951.
• Project Muse Project Muse provides online access to many scholarly journals, books, and other academic resources in the humanities, social sciences, and arts. It is also a leading provider of digital humanities content. Project MUSE offers access to diverse, high-quality, peer-reviewed journals from renowned university presses, scholarly societies, and academic publishers. It also covers various disciplines, including literature, history, philosophy, political science, sociology, cultural studies, etc. Some institutions subscribe to the Project Muse Premium Collection, which contains over 700 scholarly journals from over 100 publishers on various subjects.
• Dissertations & Theses Global ProQuest Dissertations & Theses Global is a comprehensive collection of academic theses and dissertations students submit as part of their university studies. Each dissertation or thesis provides a literature review section, offering a critical assessment of the sources used to write the work.
• Science Direct Science Direct provides a large collection of Social Sciences and Humanities journals and books, highlighting historical context, current developments, theories, applications, trends, and more.
• Social Science Citation Index™ (Web of Science) Social Sciences Citation Index™ provides access to a wide range of scholarly literature in the social sciences, including sociology, psychology, political science, anthropology, economics, and education, among others. Contains over 3,400 journals across 58 social sciences disciplines, as well as selected items from 3,500 of the world’s leading scientific and technical journals. More than 9.37 million records and 122 million cited references date back from 1900 to the present.

A relevant review of the literature (RRL) is an objective, concise, critical summary of published research literature relevant to a topic being researched in an article. In an RRL, you discuss knowledge and findings from existing literature relevant to your study topic. If there are conflicts or gaps in existing literature, you can also discuss these in your review, as well as how you will confront these missing elements or resolve these issues in your study.

To complete an RRL, you first need to collect relevant literature; this can include online and offline sources. Save all of your applicable resources as you will need to include them in your paper. When looking through these sources, take notes and identify concepts of each source to describe in the review of the literature.

A good RRL does NOT:

A literature review does not simply reference and list all of the material you have cited in your paper.

• Presenting material that is not directly relevant to your study will distract and frustrate the reader and make them lose sight of the purpose of your study.
• Starting a literature review with “A number of scholars have studied the relationship between X and Y” and simply listing who has studied the topic and what each scholar concluded is not going to strengthen your paper.

A good RRL DOES:

• Present a brief typology that orders articles and books into groups to help readers focus on unresolved debates, inconsistencies, tensions, and new questions about a research topic.
• Summarize the most relevant and important aspects of the scientific literature related to your area of research
• Synthesize what has been done in this area of research and by whom, highlight what previous research indicates about a topic, and identify potential gaps and areas of disagreement in the field
• Give the reader an understanding of the background of the field and show which studies are important—and highlight errors in previous studies

How long is a review of the literature for a research paper?

The length of a review of the literature depends on its purpose and target readership and can vary significantly in scope and depth. In a dissertation, thesis, or standalone review of literature, it is usually a full chapter of the text (at least 20 pages). Whereas, a standard research article or school assignment literature review section could only be a few paragraphs in the Introduction section .

Building Your Literature Review Bookshelf

One way to conceive of a literature review is to think about writing it as you would build a bookshelf. You don’t need to cut each piece by yourself from scratch. Rather, you can take the pieces that other researchers have cut out and put them together to build a framework on which to hang your own “books”—that is, your own study methods, results, and conclusions.

What Makes a Good Literature Review?

The contents of a literature review (RRL) are determined by many factors, including its precise purpose in the article, the degree of consensus with a given theory or tension between competing theories, the length of the article, the number of previous studies existing in the given field, etc. The following are some of the most important elements that a literature review provides.

Historical background for your research

Analyze what has been written about your field of research to highlight what is new and significant in your study—or how the analysis itself contributes to the understanding of this field, even in a small way. Providing a historical background also demonstrates to other researchers and journal editors your competency in discussing theoretical concepts. You should also make sure to understand how to paraphrase scientific literature to avoid plagiarism in your work.

The current context of your research

Discuss central (or peripheral) questions, issues, and debates in the field. Because a field is constantly being updated by new work, you can show where your research fits into this context and explain developments and trends in research.

A discussion of relevant theories and concepts

Theories and concepts should provide the foundation for your research. For example, if you are researching the relationship between ecological environments and human populations, provide models and theories that focus on specific aspects of this connection to contextualize your study. If your study asks a question concerning sustainability, mention a theory or model that underpins this concept. If it concerns invasive species, choose material that is focused in this direction.

Definitions of relevant terminology

In the natural sciences, the meaning of terms is relatively straightforward and consistent. But if you present a term that is obscure or context-specific, you should define the meaning of the term in the Introduction section (if you are introducing a study) or in the summary of the literature being reviewed.

Description of related relevant research

Include a description of related research that shows how your work expands or challenges earlier studies or fills in gaps in previous work. You can use your literature review as evidence of what works, what doesn’t, and what is missing in the field.

Supporting evidence for a practical problem or issue your research is addressing that demonstrates its importance: Referencing related research establishes your area of research as reputable and shows you are building upon previous work that other researchers have deemed significant.

Types of Literature Reviews

Literature reviews can differ in structure, length, amount, and breadth of content included. They can range from selective (a very narrow area of research or only a single work) to comprehensive (a larger amount or range of works). They can also be part of a larger work or stand on their own.

• A course assignment is an example of a selective, stand-alone work. It focuses on a small segment of the literature on a topic and makes up an entire work on its own.
• The literature review in a dissertation or thesis is both comprehensive and helps make up a larger work.
• A majority of journal articles start with a selective literature review to provide context for the research reported in the study; such a literature review is usually included in the Introduction section (but it can also follow the presentation of the results in the Discussion section ).
• Some literature reviews are both comprehensive and stand as a separate work—in this case, the entire article analyzes the literature on a given topic.

Literature Reviews Found in Academic Journals

The two types of literature reviews commonly found in journals are those introducing research articles (studies and surveys) and stand-alone literature analyses. They can differ in their scope, length, and specific purpose.

Literature reviews introducing research articles

The literature review found at the beginning of a journal article is used to introduce research related to the specific study and is found in the Introduction section, usually near the end. It is shorter than a stand-alone review because it must be limited to very specific studies and theories that are directly relevant to the current study. Its purpose is to set research precedence and provide support for the study’s theory, methods, results, and/or conclusions. Not all research articles contain an explicit review of the literature, but most do, whether it is a discrete section or indistinguishable from the rest of the Introduction.

How to structure a literature review for an article

When writing a literature review as part of an introduction to a study, simply follow the structure of the Introduction and move from the general to the specific—presenting the broadest background information about a topic first and then moving to specific studies that support your rationale , finally leading to your hypothesis statement. Such a literature review is often indistinguishable from the Introduction itself—the literature is INTRODUCING the background and defining the gaps your study aims to fill.

The stand-alone literature review

The literature review published as a stand-alone article presents and analyzes as many of the important publications in an area of study as possible to provide background information and context for a current area of research or a study. Stand-alone reviews are an excellent resource for researchers when they are first searching for the most relevant information on an area of study.

Such literature reviews are generally a bit broader in scope and can extend further back in time. This means that sometimes a scientific literature review can be highly theoretical, in addition to focusing on specific methods and outcomes of previous studies. In addition, all sections of such a “review article” refer to existing literature rather than describing the results of the authors’ own study.

In addition, this type of literature review is usually much longer than the literature review introducing a study. At the end of the review follows a conclusion that once again explicitly ties all of the cited works together to show how this analysis is itself a contribution to the literature. While not absolutely necessary, such articles often include the terms “Literature Review” or “Review of the Literature” in the title. Whether or not that is necessary or appropriate can also depend on the specific author instructions of the target journal. Have a look at this article for more input on how to compile a stand-alone review article that is insightful and helpful for other researchers in your field.

How to Write a Literature Review in 6 Steps

So how do authors turn a network of articles into a coherent review of relevant literature?

Writing a literature review is not usually a linear process—authors often go back and check the literature while reformulating their ideas or making adjustments to their study. Sometimes new findings are published before a study is completed and need to be incorporated into the current work. This also means you will not be writing the literature review at any one time, but constantly working on it before, during, and after your study is complete.

Here are some steps that will help you begin and follow through on your literature review.

Step 1: Choose a topic to write about—focus on and explore this topic.

Choose a topic that you are familiar with and highly interested in analyzing; a topic your intended readers and researchers will find interesting and useful; and a topic that is current, well-established in the field, and about which there has been sufficient research conducted for a review. This will help you find the “sweet spot” for what to focus on.

Step 2: Research and collect all the scholarly information on the topic that might be pertinent to your study.

This includes scholarly articles, books, conventions, conferences, dissertations, and theses—these and any other academic work related to your area of study is called “the literature.”

Step 3: Analyze the network of information that extends or responds to the major works in your area; select the material that is most useful.

Use thought maps and charts to identify intersections in the research and to outline important categories; select the material that will be most useful to your review.

Step 4: Describe and summarize each article—provide the essential information of the article that pertains to your study.

Determine 2-3 important concepts (depending on the length of your article) that are discussed in the literature; take notes about all of the important aspects of this study relevant to the topic being reviewed.

For example, in a given study, perhaps some of the main concepts are X, Y, and Z. Note these concepts and then write a brief summary about how the article incorporates them. In reviews that introduce a study, these can be relatively short. In stand-alone reviews, there may be significantly more texts and more concepts.

Step 5: Demonstrate how these concepts in the literature relate to what you discovered in your study or how the literature connects the concepts or topics being discussed.

In a literature review intro for an article, this information might include a summary of the results or methods of previous studies that correspond to and/or confirm those sections in your own study. For a stand-alone literature review, this may mean highlighting the concepts in each article and showing how they strengthen a hypothesis or show a pattern.

Discuss unaddressed issues in previous studies. These studies that are missing something you address are important to include in your literature review. In addition, those works whose theories and conclusions directly support your findings will be valuable to review here.

Step 6: Identify relationships in the literature and develop and connect your own ideas to them.

This is essentially the same as step 5 but focused on the connections between the literature and the current study or guiding concepts or arguments of the paper, not only on the connections between the works themselves.

Your hypothesis, argument, or guiding concept is the “golden thread” that will ultimately tie the works together and provide readers with specific insights they didn’t have before reading your literature review. Make sure you know where to put the research question , hypothesis, or statement of the problem in your research paper so that you guide your readers logically and naturally from your introduction of earlier work and evidence to the conclusions you want them to draw from the bigger picture.

Your literature review will not only cover publications on your topics but will include your own ideas and contributions. By following these steps you will be telling the specific story that sets the background and shows the significance of your research and you can turn a network of related works into a focused review of the literature.

Literature Review (RRL) Examples

Because creating sample literature reviews would take too long and not properly capture the nuances and detailed information needed for a good review, we have included some links to different types of literature reviews below. You can find links to more literature reviews in these categories by visiting the TUS Library’s website . Sample literature reviews as part of an article, dissertation, or thesis:

• Critical Thinking and Transferability: A Review of the Literature (Gwendolyn Reece)
• Building Customer Loyalty: A Customer Experience Based Approach in a Tourism Context (Martina Donnelly)

Sample stand-alone literature reviews

• Literature Review on Attitudes towards Disability (National Disability Authority)
• The Effects of Communication Styles on Marital Satisfaction (Hannah Yager)

Additional Literature Review Format Guidelines

In addition to the content guidelines above, authors also need to check which style guidelines to use ( APA , Chicago, MLA, etc.) and what specific rules the target journal might have for how to structure such articles or how many studies to include—such information can usually be found on the journals’ “Guide for Authors” pages. Additionally, use one of the four Wordvice citation generators below, choosing the citation style needed for your paper:

Research Methods

This page discusses the following topics:

Research Goals

Research method types.

Before discussing research   methods , we need to distinguish them from  methodologies  and  research skills . Methodologies, linked to literary theories, are tools and lines of investigation: sets of practices and propositions about texts and the world. Researchers using Marxist literary criticism will adopt methodologies that look to material forces like labor, ownership, and technology to understand literature and its relationship to the world. They will also seek to understand authors not as inspired geniuses but as people whose lives and work are shaped by social forces.

Example: Critical Race Theory Methodologies

Critical Race Theory may use a variety of methodologies, including

• Interest convergence: investigating whether marginalized groups only achieve progress when dominant groups benefit as well
• Intersectional theory: investigating how multiple factors of advantage and disadvantage around race, gender, ethnicity, religion, etc. operate together in complex ways
• Radical critique of the law: investigating how the law has historically been used to marginalize particular groups, such as black people, while recognizing that legal efforts are important to achieve emancipation and civil rights
• Social constructivism: investigating how race is socially constructed (rather than biologically grounded)
• Standpoint epistemology: investigating how knowledge relates to social position
• Structural determinism: investigating how structures of thought and of organizations determine social outcomes

To identify appropriate methodologies, you will need to research your chosen theory and gather what methodologies are associated with it. For the most part, we can’t assume that there are “one size fits all” methodologies.

Research skills are about how you handle materials such as library search engines, citation management programs, special collections materials, and so on.

Research methods  are about where and how you get answers to your research questions. Are you conducting interviews? Visiting archives? Doing close readings? Reviewing scholarship? You will need to choose which methods are most appropriate to use in your research and you need to gain some knowledge about how to use these methods. In other words, you need to do some research into research methods!

Your choice of research method depends on the kind of questions you are asking. For example, if you want to understand how an author progressed through several drafts to arrive at a final manuscript, you may need to do archival research. If you want to understand why a particular literary work became a bestseller, you may need to do audience research. If you want to know why a contemporary author wrote a particular work, you may need to do interviews. Usually literary research involves a combination of methods such as  archival research ,  discourse analysis , and  qualitative research  methods.

Literary research methods tend to differ from research methods in the hard sciences (such as physics and chemistry). Science research must present results that are reproducible, while literary research rarely does (though it must still present evidence for its claims). Literary research often deals with questions of meaning, social conventions, representations of lived experience, and aesthetic effects; these are questions that reward dialogue and different perspectives rather than one great experiment that settles the issue. In literary research, we might get many valuable answers even though they are quite different from one another. Also in literary research, we usually have some room to speculate about answers, but our claims have to be plausible (believable) and our argument comprehensive (meaning we don’t overlook evidence that would alter our argument significantly if it were known).

A literary researcher might select the following:

Theory: Critical Race Theory

Methodology: Social Constructivism

Method: Scholarly

Skills: Search engines, citation management

Wendy Belcher, in  Writing Your Journal Article in 12 Weeks , identifies two main approaches to understanding literary works: looking at a text by itself (associated with New Criticism ) and looking at texts as they connect to society (associated with Cultural Studies ). The goal of New Criticism is to bring the reader further into the text. The goal of Cultural Studies is to bring the reader into the network of discourses that surround and pass through the text. Other approaches, such as Ecocriticism, relate literary texts to the Sciences (as well as to the Humanities).

The New Critics, starting in the 1940s,  focused on meaning within the text itself, using a method they called “ close reading .” The text itself becomes e vidence for a particular reading. Using this approach, you should summarize the literary work briefly and q uote particularly meaningful passages, being sure to introduce quotes and then interpret them (never let them stand alone). Make connections within the work; a sk  “why” and “how” the various parts of the text relate to each other.

Cultural Studies critics see all texts  as connected to society; the critic  therefore has to connect a text to at least one political or social issue. How and why does  the text reproduce particular knowledge systems (known as discourses) and how do these knowledge systems relate to issues of power within the society? Who speaks and when? Answering these questions helps your reader understand the text in context. Cultural contexts can include the treatment of gender (Feminist, Queer), class (Marxist), nationality, race, religion, or any other area of human society.

Other approaches, such as psychoanalytic literary criticism , look at literary texts to better understand human psychology. A psychoanalytic reading can focus on a character, the author, the reader, or on society in general. Ecocriticism  look at human understandings of nature in literary texts.

We select our research methods based on the kinds of things we want to know. For example, we may be studying the relationship between literature and society, between author and text, or the status of a work in the literary canon. We may want to know about a work’s form, genre, or thematics. We may want to know about the audience’s reading and reception, or about methods for teaching literature in schools.

Below are a few research methods and their descriptions. You may need to consult with your instructor about which ones are most appropriate for your project. The first list covers methods most students use in their work. The second list covers methods more commonly used by advanced researchers. Even if you will not be using methods from this second list in your research project, you may read about these research methods in the scholarship you find.

Most commonly used undergraduate research methods:

• Scholarship Methods:  Studies the body of scholarship written about a particular author, literary work, historical period, literary movement, genre, theme, theory, or method.
• Textual Analysis Methods:  Used for close readings of literary texts, these methods also rely on literary theory and background information to support the reading.
• Biographical Methods:  Used to study the life of the author to better understand their work and times, these methods involve reading biographies and autobiographies about the author, and may also include research into private papers, correspondence, and interviews.
• Discourse Analysis Methods:  Studies language patterns to reveal ideology and social relations of power. This research involves the study of institutions, social groups, and social movements to understand how people in various settings use language to represent the world to themselves and others. Literary works may present complex mixtures of discourses which the characters (and readers) have to navigate.
• Creative Writing Methods:  A literary re-working of another literary text, creative writing research is used to better understand a literary work by investigating its language, formal structures, composition methods, themes, and so on. For instance, a creative research project may retell a story from a minor character’s perspective to reveal an alternative reading of events. To qualify as research, a creative research project is usually combined with a piece of theoretical writing that explains and justifies the work.

Methods used more often by advanced researchers:

• Archival Methods: Usually involves trips to special collections where original papers are kept. In these archives are many unpublished materials such as diaries, letters, photographs, ledgers, and so on. These materials can offer us invaluable insight into the life of an author, the development of a literary work, or the society in which the author lived. There are at least three major archives of James Baldwin’s papers: The Smithsonian , Yale , and The New York Public Library . Descriptions of such materials are often available online, but the materials themselves are typically stored in boxes at the archive.
• Computational Methods:  Used for statistical analysis of texts such as studies of the popularity and meaning of particular words in literature over time.
• Ethnographic Methods:  Studies groups of people and their interactions with literary works, for instance in educational institutions, in reading groups (such as book clubs), and in fan networks. This approach may involve interviews and visits to places (including online communities) where people interact with literary works. Note: before you begin such work, you must have  Institutional Review Board (IRB)  approval “to protect the rights and welfare of human participants involved in research.”
• Visual Methods:  Studies the visual qualities of literary works. Some literary works, such as illuminated manuscripts, children’s literature, and graphic novels, present a complex interplay of text and image. Even works without illustrations can be studied for their use of typography, layout, and other visual features.

Regardless of the method(s) you choose, you will need to learn how to apply them to your work and how to carry them out successfully. For example, you should know that many archives do not allow you to bring pens (you can use pencils) and you may not be allowed to bring bags into the archives. You will need to keep a record of which documents you consult and their location (box number, etc.) in the archives. If you are unsure how to use a particular method, please consult a book about it. [1] Also, ask for the advice of trained researchers such as your instructor or a research librarian.

• What research method(s) will you be using for your paper? Why did you make this method selection over other methods? If you haven’t made a selection yet, which methods are you considering?
• What specific methodological approaches are you most interested in exploring in relation to the chosen literary work?
• What is your plan for researching your method(s) and its major approaches?
• What was the most important lesson you learned from this page? What point was confusing or difficult to understand?

Ten Simple Rules for Writing a Literature Review

Marco pautasso.

1 Centre for Functional and Evolutionary Ecology (CEFE), CNRS, Montpellier, France

2 Centre for Biodiversity Synthesis and Analysis (CESAB), FRB, Aix-en-Provence, France

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

• interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
• an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
• a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

• keep track of the search items you use (so that your search can be replicated [10] ),
• keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
• use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
• define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
• do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

• discussing in your review the approaches, limitations, and conclusions of past reviews,
• trying to find a new angle that has not been covered adequately in the previous reviews, and
• incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

• be thorough,
• use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
• look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

• the major achievements in the reviewed field,
• the main areas of debate, and
• the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

Exploring Connections Through Global Literary Studies

Good news for fans of the written word: The UW College of Arts & Sciences (CAS) has introduced a new major, Global Literary Studies (GLITS). Through GLITS, students can study Nobel Prize-winning literature, traditional Chinese poetry, environmental literature, Korean comics, Indigenous literature, Viking sagas, crime fiction, literature about medicine, fairy tales, and much more.

The GLITS major is designed to encourage exploration of literary traditions from around the globe and all eras of human history. Works are presented in English, in a wide range of genres.

“The major is designed to be accessible to the widest range of students possible who are interested in literature,” says Brian Reed, CAS divisional dean of humanities. “The motto of the humanities is ‘We open the world.’  This is an opportunity for our students to gain a range of important experiences en route to becoming better global citizens in a world where communication is essential.”

Literary Connections Across Time, Place, and Genre

All GLITS majors take an introductory course that delves into central questions of literary study: What is literature? How can we think about literature on a global scale? They finish the major with a final course that reflects on their literary journey. Between those bookends, they have tremendous flexibility in the courses they take, making GLITS an ideal second major for any student with an appreciation for literature.

“There’s no way anyone can survey, let alone delve deeply, into the literature of the world from the beginning of human language until now,” says Gordana Crnković, co-director of the new GLITS major and professor and chair of the Department of Slavic Languages & Literatures (SLL). “But GLITS students do get a great sense of different ways of thinking and language use. If they can expand their language and literary horizons by this study, it will serve them their whole life.”

We’re committed to this because we love literature, and we think that our students also deserve a chance to love it. Naomi Sokoloff Co-Director of Global & Literary Studies; Professor and Chair of Middle Eastern Languages & Cultures

To ensure that students gain a breadth of literary knowledge, GLITS majors take courses in five categories — literature across time, across place, across languages, across genres, and across disciplines — with dozens of courses to choose from. For the literature-across-time category, students might take “The Classical Tradition,” a course that explores connections between ancient and modern texts and ideas. For literature across place, “Indigenous Illuminations” explores work from Indigenous groups around the globe. “Literature and Science” considers how literature can communicate scientific questions in impactful ways. Some courses are team taught, including “Cross-Cultural Encounters in the Middle Ages,” in which instructors from two departments explore how European encounters with the Middle East and Far East during the Middle Ages are expressed in literary works.

A New Model for a Major

Crnković began brainstorming the idea of a GLITS major five years ago with two colleagues, Naomi Sokoloff and Gary Handwerk. Sokoloff, GLITS co-director, is professor and chair of the Department of Middle Eastern Languages and Cultures . Handwerk, professor of comparative history of ideas and comparative literature  is director of the UW Program on the Environment  and Bruce J. Leven Professor of Environmental Studies.

With the support of Reed and other CAS leadership, Crnković, Sokoloff, and Handwerk served as a task force to explore the potential benefits and hurdles of creating a global literature major. The benefits inspired them, but the hurdles… well, there’s a reason the major took five years to finalize.

The most obvious challenge: GLITS was envisioned as a divisional major, shared by nearly a dozen departments. That model was new. On top of that, the major would not have a single faculty position of its own. “We basically had to reconfigure what already existed in departments,” says Crnković, referring to existing faculty and courses. “We needed people to think with us in a different way.”

Early on, the task force met with Humanities department chairs to get their input and buy-in, and several symposia were held to strengthen ties between humanities scholars at the UW. “Global Literatures, Global Literacies,” an online symposium hosted by the UW’s Simpson Center for the Humanities in 2021, featured five-minute talks by 20 humanities faculty about a global literature course they were already teaching or planning to teach. Those talks were a powerful motivator for the task force team.

“I think many of us in the humanities have felt that we were in silos,” says Sokoloff. “We felt isolated at times. This was a chance to get to know one another. And it turns out that we have really great faculty here.”

"A Heroic, Tremendous Effort"

To ensure the ongoing success of GLITS, a six-member GLITS steering committee will continue to build the major. Steering committee members come from departments across the humanities, with Crnković and Sokoloff currently coordinating their efforts as GLITS co-directors. For logistical reasons, GLITS is housed in the Department of Slavic Languages & Literatures, but the steering committee, with its rotating membership, ensures that a range of specialties, backgrounds, and points of view are represented.

The mammoth achievement of the new major has not been lost on Reed. He describes his role in the process as “advocate and connector,” noting that Crnković, Sokoloff, and Handwerk did the heavy lifting in bringing this idea to fruition.

“This has required vision and persistence and commitment,” Reed says. “The three of them had to step away from their own scholarly commitments and embrace the idea of collaboration and institutional change. Along the way, they had to deal with a lot of bureaucracy and setbacks. It’s really been a heroic, tremendous effort, and I am so grateful for their involvement.”

Sokoloff appreciates the sentiment but insists that GLITS has been a labor of love.

“We’re committed to this because we love literature, and we think that our students also deserve a chance to love it,” she says.
