In the social sciences, a secondary source is usually a scholar book, journal article, or digital or print document that was created by someone who did not directly experience or participate in the events or conditions under investigation. Secondary sources are not evidence per se, but rather, provide an interpretation, analysis, or commentary derived from the content of primary source materials and/or other secondary sources.

Value of Secondary Sources

To do research, you must cite research. Primary sources do not represent research per se, but only the artifacts from which most research is derived. Therefore, the majority of sources in a literature review are secondary sources that present research findings, analysis, and the evaluation of other researcher's works.

Reviewing secondary source material can be of valu e in improving your overall research paper because secondary sources facilitate the communication of what is known about a topic. This literature also helps you understand the level of uncertainty about what is currently known and what additional information is needed from further research. It is important to note, however, that secondary sources are not the subject of your analysis. Instead, they represent various opinions, interpretations, and arguments about the research problem you are investigating--opinions, interpretations, and arguments with which you may either agree or disagree with as part of your own analysis of the literature.

Examples of secondary sources you could review as part of your overall study include:     * Bibliographies [also considered tertiary]     * Biographical works     * Books, other than fiction and autobiography     * Commentaries, criticisms     * Dictionaries, Encyclopedias [also considered tertiary]     * Histories     * Journal articles [depending on the discipline, they can be primary]     * Magazine and newspaper articles [this distinction varies by discipline]     * Textbooks [also considered tertiary]     * Web site [also considered primary]

Whether you are in the process of writing a research essay for school or you're drafting a persuasive opinion article for the student newspaper, you'll want to support your assertions with appropriate sources. This adds credibility to your writing because it means that you're not pulling ideas and facts out of thin air.

Generally speaking, you'll find that these sources come in one of two types: primary sources vs. secondary sources. What's the difference between the two? Primary sources are typically the raw materials or the original content, providing a first-hand account of the events. Secondary sources, on the other hand, are one step removed from the original content. Sometimes, they'll analyze, restate, or describe the contents of primary sources.

Both primary and secondary sources have their place. They also have their respective pros and cons. Let's look into the role of primary sources vs. secondary sources.

Primary Sources

A primary source is an original document or other piece of material that was created at the time of the actual events or within its time period. The material is ideally created by someone who is known and can be named, and it was produced for a known purpose.

In other words, a primary source is the raw material that is produced from a first-hand account or as close to a first-hand account as is available. The transcript of an interview with an eyewitness is still considered a primary source.

Examples of Primary Sources

Some examples of primary sources include the following.

• Original manuscripts
• Audio recordings
• Research articles published in peer-reviewed journals
• Original documents and artifacts
• Personal diaries, letters, emails
• Autobiographies
• Photographs and video recordings
• Meeting minutes
• Survey results
• Newspaper articles with original reporting
• Original research reports

In this way, a book like The Diary of Anne Frank is considered a primary source. So are the Declaration of Independence and photographs recovered from the Vietnam War.

Advantages of Primary Sources

The biggest advantage of referring to a primary source is that you can have confidence in knowing that the original material is untarnished and intact. It has not been misinterpreted by outside parties, because you're getting the story straight from the horse's mouth .

The material can generally be tracked and attributed back to the original creator, giving much more weight to the points being referenced. You are less subject to subsequent misinterpretations and assumptions made after the fact.

Disadvantages of Primary Sources

As powerful as primary sources may be, they may also be incomplete or unusable. For example, if the writing or audio recording is in another language that you do not speak, you wouldn't understand anything being said. And even if it is in English, you may not have enough context to grasp the full extent of what is being said.

When you rely solely on primary sources, you are also relying solely on your own knowledge and interpretation. That may not be sufficient in really extracting as much value as possible out of the original materials.

Secondary Sources

Whereas primary sources are generally the original material, a secondary source builds upon one or more primary sources. Often, secondary sources will interpret, analyze, explain or describe content from primary sources.

In some cases, secondary sources can attempt to remain reasonably neutral in their presentation of the facts. In other cases, secondary sources can use them to argue a point or try to persuade the reader of a particular opinion.

Examples of Secondary Sources

Common examples of secondary sources include the following:

• Scholarly or critical analysis
• Commentary or editorial content
• Encyclopedias
• Biographies
• Magazine articles (particularly opinion pieces)
• Documentary films
• Second-hand news reporting

So, while The Diary of Anne Frank is a primary source, a book that analyzes Frank's diary and provides more historical context for its entries would be considered a secondary source. Similarly, an autobiography written by Barack Obama is a primary source, but a biography written by someone else about Barack Obama would be considered a secondary source.

Advantages of Secondary Sources

Unsurprisingly, the main advantages of secondary sources largely address the disadvantages of primary sources. Since secondary sources aim to expand upon the material in original sources, they can provide a lot more context and meaning. This supporting information can provide much greater insight, taking advantage of the author's expertise, experience, and research - going above and beyond what you may have been able to glean from the original content.

Disadvantages of Secondary Sources

The challenge with secondary sources is that you are inherently viewing the original material through the lens of a different writer or content producer. Their experiences and biases will color how the information is presented. Two different authors can interpret the same piece of original material in two wildly different ways.

As such, secondary sources are unreliable as primary points of evidence. Instead, they're better served as sources of commentary and interpretation.

Side-by-Side Sources Comparison

A great way to understand the difference between primary and secondary sources is to look at them side-by-side, particularly when they are discussing the same story or issue.

Remember to Cite Everything

Primary sources are not necessarily better than secondary sources, and secondary sources are not necessarily better than primary sources. Both serve a different purpose, and both can be integrated into your own research and writing. You do have to ensure that you are only using credible sources for your work though.

Also, just be sure to cite your sources appropriately, both primary and secondary, by including a properly formatted bibliography as part of your report. This way, your readers will know where you got your information and can follow up with their own research if they'd like.

Secondary Research Advantages, Limitations, and Sources

Summary: secondary research should be a prerequisite to the collection of primary data, but it rarely provides all the answers you need. a thorough evaluation of the secondary data is needed to assess its relevance and accuracy..

5 minutes to read. By author Michaela Mora on January 25, 2022 Topics: Relevant Methods & Tips , Business Strategy , Market Research

Secondary research is based on data already collected for purposes other than the specific problem you have. Secondary research is usually part of exploratory market research designs.

The connection between the specific purpose that originates the research is what differentiates secondary research from primary research. Primary research is designed to address specific problems. However, analysis of available secondary data should be a prerequisite to the collection of primary data.

Advantages of Secondary Research

Secondary data can be faster and cheaper to obtain, depending on the sources you use.

Secondary research can help to:

• Answer certain research questions and test some hypotheses.
• Formulate an appropriate research design (e.g., identify key variables).
• Interpret data from primary research as it can provide some insights into general trends in an industry or product category.
• Understand the competitive landscape.

Limitations of Secondary Research

The usefulness of secondary research tends to be limited often for two main reasons:

Lack of relevance

Secondary research rarely provides all the answers you need. The objectives and methodology used to collect the secondary data may not be appropriate for the problem at hand.

Given that it was designed to find answers to a different problem than yours, you will likely find gaps in answers to your problem. Furthermore, the data collection methods used may not provide the data type needed to support the business decisions you have to make (e.g., qualitative research methods are not appropriate for go/no-go decisions).

Lack of Accuracy

Secondary data may be incomplete and lack accuracy depending on;

• The research design (exploratory, descriptive, causal, primary vs. repackaged secondary data, the analytical plan, etc.)
• Sampling design and sources (target audiences, recruitment methods)
• Data collection method (qualitative and quantitative techniques)
• Analysis point of view (focus and omissions)
• Reporting stages (preliminary, final, peer-reviewed)
• Rate of change in the studied topic (slowly vs. rapidly evolving phenomenon, e.g., adoption of specific technologies).
• Lack of agreement between data sources.

Criteria for Evaluating Secondary Research Data

Before taking the information at face value, you should conduct a thorough evaluation of the secondary data you find using the following criteria:

• Purpose : Understanding why the data was collected and what questions it was trying to answer will tell us how relevant and useful it is since it may or may not be appropriate for your objectives.
• Methodology used to collect the data : Important to understand sources of bias.
• Accuracy of data: Sources of errors may include research design, sampling, data collection, analysis, and reporting.
• When the data was collected : Secondary data may not be current or updated frequently enough for the purpose that you need.
• Content of the data : Understanding the key variables, units of measurement, categories used and analyzed relationships may reveal how useful and relevant it is for your purposes.
• Source reputation : In the era of purposeful misinformation on the Internet, it is important to check the expertise, credibility, reputation, and trustworthiness of the data source.

Secondary Research Data Sources

Compared to primary research, the collection of secondary data can be faster and cheaper to obtain, depending on the sources you use.

Secondary data can come from internal or external sources.

Internal sources of secondary data include ready-to-use data or data that requires further processing available in internal management support systems your company may be using (e.g., invoices, sales transactions, Google Analytics for your website, etc.).

Prior primary qualitative and quantitative research conducted by the company are also common sources of secondary data. They often generate more questions and help formulate new primary research needed.

However, if there are no internal data collection systems yet or prior research, you probably won’t have much usable secondary data at your disposal.

External sources of secondary data include:

• Published materials
• External databases
• Syndicated services.

Published Materials

Published materials can be classified as:

• General business sources: Guides, directories, indexes, and statistical data.
• Government sources: Census data and other government publications.

External Databases

In many industries across a variety of topics, there are private and public databases that can bed accessed online or by downloading data for free, a fixed fee, or a subscription.

These databases can include bibliographic, numeric, full-text, directory, and special-purpose databases. Some public institutions make data collected through various methods, including surveys, available for others to analyze.

Syndicated Services

These services are offered by companies that collect and sell pools of data that have a commercial value and meet shared needs by a number of clients, even if the data is not collected for specific purposes those clients may have.

Syndicated services can be classified based on specific units of measurements (e.g., consumers, households, organizations, etc.).

The data collection methods for these data may include:

• Surveys (Psychographic and Lifestyle, advertising evaluations, general topics)
• Household panels (Purchase and media use)
• Electronic scanner services (volume tracking data, scanner panels, scanner panels with Cable TV)
• Audits (retailers, wholesalers)
• Direct inquiries to institutions
• Clipping services tracking PR for institutions
• Corporate reports

You can spend hours doing research on Google in search of external sources, but this is likely to yield limited insights. Books, articles journals, reports, blogs posts, and videos you may find online are usually analyses and summaries of data from a particular perspective. They may be useful and give you an indication of the type of data used, but they are not the actual data. Whenever possible, you should look at the actual raw data used to draw your own conclusion on its value for your research objectives. You should check professionally gathered secondary research.

Here are some external secondary data sources often used in market research that you may find useful as starting points in your research. Some are free, while others require payment.

• Pew Research Center : Reports about the issues, attitudes, and trends shaping the world. It conducts public opinion polling, demographic research, media content analysis, and other empirical social science research.
• Data.Census.gov : Data dissemination platform to access demographic and economic data from the U.S. Census Bureau.

Secondary Research Guide: Definition, Methods, Examples

Apr 3, 2024

8 min. read

The internet has vastly expanded our access to information, allowing us to learn almost anything about everything. But not all market research is created equal , and this secondary research guide explains why.

There are two key ways to do research. One is to test your own ideas, make your own observations, and collect your own data to derive conclusions. The other is to use secondary research — where someone else has done most of the heavy lifting for you. 

Here’s an overview of secondary research and the value it brings to data-driven businesses.

Secondary Research Definition: What Is Secondary Research?

Primary vs Secondary Market Research

What Are Secondary Research Methods?

Advantages of secondary research, disadvantages of secondary research, best practices for secondary research, how to conduct secondary research with meltwater.

Secondary research definition: The process of collecting information from existing sources and data that have already been analyzed by others.

Secondary research (aka desk research ) provides a foundation to help you understand a topic, with the goal of building on existing knowledge. They often cover the same information as primary sources, but they add a layer of analysis and explanation to them.

Users can choose from several secondary research types and sources, including:

• Journal articles
• Research papers

With secondary sources, users can draw insights, detect trends , and validate findings to jumpstart their research efforts.

Primary vs. Secondary Market Research

We’ve touched a little on primary research , but it’s essential to understand exactly how primary and secondary research are unique.

Think of primary research as the “thing” itself, and secondary research as the analysis of the “thing,” like these primary and secondary research examples:

• An expert gives an interview (primary research) and a marketer uses that interview to write an article (secondary research).
• A company conducts a consumer satisfaction survey (primary research) and a business analyst uses the survey data to write a market trend report (secondary research).
• A marketing team launches a new advertising campaign across various platforms (primary research) and a marketing research firm, like Meltwater for market research , compiles the campaign performance data to benchmark against industry standards (secondary research).

In other words, primary sources make original contributions to a topic or issue, while secondary sources analyze, synthesize, or interpret primary sources.

Both are necessary when optimizing a business, gaining a competitive edge , improving marketing, or understanding consumer trends that may impact your business.

Secondary research methods focus on analyzing existing data rather than collecting primary data . Common examples of secondary research methods include:

• Literature review . Researchers analyze and synthesize existing literature (e.g., white papers, research papers, articles) to find knowledge gaps and build on current findings.
• Content analysis . Researchers review media sources and published content to find meaningful patterns and trends.
• AI-powered secondary research . Platforms like Meltwater for market research analyze vast amounts of complex data and use AI technologies like natural language processing and machine learning to turn data into contextual insights.

Researchers today have access to more secondary research companies and market research tools and technology than ever before, allowing them to streamline their efforts and improve their findings.

Want to see how Meltwater can complement your secondary market research efforts? Simply fill out the form at the bottom of this post, and we'll be in touch.

Conducting secondary research offers benefits in every job function and use case, from marketing to the C-suite. Here are a few advantages you can expect.

Cost and time efficiency

Using existing research saves you time and money compared to conducting primary research. Secondary data is readily available and easily accessible via libraries, free publications, or the Internet. This is particularly advantageous when you face time constraints or when a project requires a large amount of data and research.

Access to large datasets

Secondary data gives you access to larger data sets and sample sizes compared to what primary methods may produce. Larger sample sizes can improve the statistical power of the study and add more credibility to your findings.

Ability to analyze trends and patterns

Using larger sample sizes, researchers have more opportunities to find and analyze trends and patterns. The more data that supports a trend or pattern, the more trustworthy the trend becomes and the more useful for making decisions. 

Historical context

Using a combination of older and recent data allows researchers to gain historical context about patterns and trends. Learning what’s happened before can help decision-makers gain a better current understanding and improve how they approach a problem or project.

Basis for further research

Ideally, you’ll use secondary research to further other efforts . Secondary sources help to identify knowledge gaps, highlight areas for improvement, or conduct deeper investigations.

Tip: Learn how to use Meltwater as a research tool and how Meltwater uses AI.

Secondary research comes with a few drawbacks, though these aren’t necessarily deal breakers when deciding to use secondary sources.

Reliability concerns

Researchers don’t always know where the data comes from or how it’s collected, which can lead to reliability concerns. They don’t control the initial process, nor do they always know the original purpose for collecting the data, both of which can lead to skewed results.

Potential bias

The original data collectors may have a specific agenda when doing their primary research, which may lead to biased findings. Evaluating the credibility and integrity of secondary data sources can prove difficult.

Outdated information

Secondary sources may contain outdated information, especially when dealing with rapidly evolving trends or fields. Using outdated information can lead to inaccurate conclusions and widen knowledge gaps.

Limitations in customization

Relying on secondary data means being at the mercy of what’s already published. It doesn’t consider your specific use cases, which limits you as to how you can customize and use the data.

A lack of relevance

Secondary research rarely holds all the answers you need, at least from a single source. You typically need multiple secondary sources to piece together a narrative, and even then you might not find the specific information you need.

To make secondary market research your new best friend, you’ll need to think critically about its strengths and find ways to overcome its weaknesses. Let’s review some best practices to use secondary research to its fullest potential.

Identify credible sources for secondary research

To overcome the challenges of bias, accuracy, and reliability, choose secondary sources that have a demonstrated history of excellence . For example, an article published in a medical journal naturally has more credibility than a blog post on a little-known website.

Assess credibility based on peer reviews, author expertise, sampling techniques, publication reputation, and data collection methodologies. Cross-reference the data with other sources to gain a general consensus of truth.

The more credibility “factors” a source has, the more confidently you can rely on it. 

Evaluate the quality and relevance of secondary data

You can gauge the quality of the data by asking simple questions:

• How complete is the data? 
• How old is the data? 
• Is this data relevant to my needs?
• Does the data come from a known, trustworthy source?

It’s best to focus on data that aligns with your research objectives. Knowing the questions you want to answer and the outcomes you want to achieve ahead of time helps you focus only on data that offers meaningful insights.

Document your sources 

If you’re sharing secondary data with others, it’s essential to document your sources to gain others’ trust. They don’t have the benefit of being “in the trenches” with you during your research, and sharing your sources can add credibility to your findings and gain instant buy-in.

Secondary market research offers an efficient, cost-effective way to learn more about a topic or trend, providing a comprehensive understanding of the customer journey . Compared to primary research, users can gain broader insights, analyze trends and patterns, and gain a solid foundation for further exploration by using secondary sources.

Meltwater for market research speeds up the time to value in using secondary research with AI-powered insights, enhancing your understanding of the customer journey. Using natural language processing, machine learning, and trusted data science processes, Meltwater helps you find relevant data and automatically surfaces insights to help you understand its significance.

Primary, Secondary & Tertiary Sources

What they are and how they compare (with examples)

By: Derek Jansen (MBA) | Expert Reviewed By: Kerryn Warren (PhD) | January 2023

If you’re new to the wild world of research, you’re bound to encounter the terrible twins, “ primary source ” and “ secondary source ” sooner or later. With any luck, “ tertiary sources ” will get thrown into the mix too! In this post, we’ll unpack both what this terminology means and how to apply it to your research project.

Overview: Source Types

• Primary sources
• Examples of primary sources
• Pros and cons of primary data
• Secondary sources
• Examples of secondary sources
• Pros and cons of secondary data
• Tertiary sources
• Summary & recap

What are primary sources?

Simply put, primary sources (also referred to as primary data) are the original raw materials, evidence or data collected in a study. Primary sources can include interview transcripts, quantitative survey data, as well as other media that provide firsthand accounts of events or phenomena. Primary sources are often considered to be the purest sources because they provide direct, unfiltered data which has not been processed or interpreted in any way.

In addition to the above, examples of primary sources can include

• Results from a social media poll
• Letters written by a historical figure
• Photographs taken during a specific time period
• Government documents such as birth certificates and census records
• Artefacts like clothing and tools from past cultures

Naturally, working with primary data has both benefits and drawbacks. Some of the main advantages include

• Purity : primary sources provide firsthand accounts of events, ideas, and experiences, which means you get access to the rawest, purest form of data.
• Perspective : primary sources allow you to gain a deeper understanding of the perspectives of the people who created them, providing insights into how different groups of people viewed an event or phenomenon.
• Richness : primary data often provide a wealth of detail and nuance that can be missed in secondary data (we’ll cover that shortly). This can provide you with a more complete and nuanced understanding of their topic.

On the flip side, some of the main disadvantages include

• Bias : given their “rawness”, primary sources can often contain biases that can skew or limit your understanding of the issue at hand.
• Inaccessibility : sometimes, collecting fresh primary data can be difficult or even impossible. For example, photographs held in private collections or letters written in a language that you’re not fluent in.
• Fragility : physical artefacts such as manuscripts may be fragile and require special handling, which can make them difficult for you to access or study.
• Limited scope : primary sources often only provide a glimpse of a particular event, person, or period of time, so you may need to rely on multiple primary sources to gain a more complete understanding of a topic.

As you can see, the strengths and weaknesses of primary sources are oftentimes two sides of the same coin . For example, primary data allow you to gain insight into peoples’ unique perspectives, but at the same time, it bakes in a significant level of each participant’s personal bias. So, it’s important to carefully consider what your research aim is and whether it lends itself to this type of data source.

Now that you’ve got a clearer picture of what primary sources/data are, let’s take a look at secondary sources.

What are secondary sources?

Secondary sources are materials that provide an analysis or interpretation of primary sources (primary data). For example, secondary sources of information can include books, journal articles and documentaries . Unlike primary sources (which are raw and uninterpreted), secondary sources provide a distilled, interpreted view of the data.

Other examples of secondary sources include

• A book that provides an analysis of an event
• A biography of a pop icon
• An article that provides an interpretation of a public opinion poll
• A blog post that reviews and compares the performance of competing products

As with primary sources, secondary sources have their own set of pros and cons. Some of the main advantages include:

• Convenience: secondary sources are often easier to access and use than primary sources, as they are widely available in libraries, journal databases, etc.
• Interpretation and synthesis : secondary sources provide a synthesis of the topic of interest, which can help you to quickly understand the most important takeaways from a data set.
• Time-saving : secondary sources can save you time, as you don’t need to analyse primary sources yourself – you can just read summaries or interpretations provided by experts in the field.

At the same time, it’s important to be aware of the disadvantages of secondary sources. Some of the main ones to consider are

• Distance from original sources : secondary sources are based on primary data, but the information has been filtered through the lens of the author, which will naturally carry some level of bias and perhaps even a hidden agenda.
• Limited context: secondary sources may not provide the same level of contextual information or detail as primary sources, which can limit your understanding of the situation and contribute toward a warped understanding.
• Inaccuracies : since secondary sources are the product of human efforts, they may contain inaccuracies or errors, especially if the author has misinterpreted primary data.
• Outdated information : secondary sources may be based on primary sources that are no longer valid or accurate, or they may not take into account more recent research or discoveries.

It’s important to mention that primary and secondary data are not mutually exclusive . In other words, it doesn’t always need to be one or the other. Secondary sources can be used to supplement primary data by providing additional information or context for a particular topic.

For example, if you were researching Martin Luther King Jr., your primary source could be transcripts of the speeches he gave during the civil rights movement. To supplement this information, you could then use secondary sources such as biographies written about him or newspaper articles from the time period in which he was active.

So, once again, it’s important to think about what you’re trying to achieve with your research – that is to say, what are your research aims? As with all methodological choices, your decision to make use of primary or secondary data (or both), needs to be informed by your overall research aims .

Before we wrap up though, it’s important to look at one more source type – tertiary sources.

Need a helping hand?

What are tertiary sources?

Last but not least, we’ve got tertiary sources . Simply put, tertiary sources are materials that provide a general overview of a topic . They often summarise or synthesise information from a combination of primary and secondary sources, such as books, articles, and other documents.

Some examples of tertiary sources include

• Encyclopedias
• Study guides
• Dictionaries

Tertiary sources can be useful when you’re just starting to learn about a completely new topic , as they provide an overview of the subject matter without getting too in-depth into specific details. For example, if you’re researching the history of World War II, but don’t know much about it yet, reading an encyclopedia article (or Wikipedia article) on the war would be helpful in providing you with some basic facts and background information.

Tertiary sources are also useful in terms of providing a starting point for citations to primary and secondary source material which can help guide your search for more detailed, credible information on a particular topic. Additionally, these types of resources may also contain lists of related topics or keywords which you can use to find more information regarding your topic of interest.

Importantly, while tertiary sources are a valuable starting point for your research, they’re not ideal sources to cite in your dissertation, thesis or research project. Instead, you should aim to cite high-quality, credible secondary sources such as peer-reviewed journal articles and research papers . So, remember to only use tertiary sources as a starting point. Don’t make the classic mistake of citing Wikipedia as your main source!

Let’s recap

In this post, we’ve explored the trinity of sources: primary, secondary and tertiary.

• Primary sources include the original raw evidence or data that you collect yourself in a study. For example, interview transcripts or statistical data.
• Secondary sources include distilled analyses and interpretations of primary data that someone else collected in their study. For example, journal articles and critical analysis pieces.
• Tertiary sources include materials that provide a general overview of a topic. For example, encyclopedias, study guides and handbooks.
• Each source type has its own set of strengths and weaknesses , and can play a different role within a research project.
• Primary sources and secondary sources are not necessarily mutually exclusive – they can work together to provide a comprehensive view.
• It’s important to ensure that your choice of source (or sources) is guided by and aligned with your research aims .

Primary, Secondary, & Tertiary Sources

What are secondary sources?

Secondary sources depend upon primary sources. Secondary sources describe, discuss, interpret, comment upon, analyze, evaluate, summarize, and process primary sources. The important thing to keep in mind when trying to decide if a source is primary or secondary is whether or not the author did the thing they are reporting on. If they did, it is a primary source; if they did not, it is a secondary source.

What is the role of secondary sources in research?

Secondary sources represent the scholarly conversation that has taken place, or is currently taking place, on a given topic. Thus, it is imperative that researchers acquire a comprehensive knowledge of the secondary literature on their topic to be able to then engage with it and offer their own perspective through their writing. Scholars show their deep knowledge of their topic by demonstrating in their writing their awareness of secondary literature. Research that does not include substantial references to both primary and secondary sources is not likely to be authoritative or reliable. For that reason, looking at the listed references in a piece of research can help you determine its value.

What are some examples of secondary sources?

Like primary sources, secondary sources can be lots of different kinds of resources depending on discipline and application. Secondary sources can be:

• Journal articles
• Monographs (books written on a single subject)
• Newspaper or magazine articles
• Book or movie reviews 

In the sciences, secondary sources tend to be things like literature reviews (synthesized descriptions of previous scholarship on a topic), systematic reviews (overviews of primary sources on a topic), or meta analyses (studies in which conclusions are drawn from consideration of systematic reviews).

In the humanities, secondary sources tend to be journal articles that discuss or evaluate someone else's research, monographs, or reviews.

Secondary Sources in Research

Other Academics' Observations on Primary Sources

• B.A., English, State University of New York

In contrast to primary sources in  research  activities, secondary sources consist of information that has been gathered and often interpreted by other researchers and recorded in books, articles, and other publications. 

In her "Handbook of Research Methods , "  Natalie L. Sproull points out that secondary sources "are not necessarily worse than primary sources and can be quite valuable. A secondary source may include more information about more aspects of the event than did a primary source ."

Most often though, secondary sources act as a way to keep up with or discuss progress in a field of study, wherein a writer may use another's observations on a topic to summarize his or her own viewpoints on the matter to progress the discourse further.

The Difference Between Primary and Secondary Data

In the hierarchy of the relevance of the evidence to an argument, primary sources like original documents and first-hand accounts of events provide the strongest support to any given claim. By contrast, secondary sources provide a type of back-up to their primary counterparts.

To help explain this difference, Ruth Finnegan distinguishes primary sources as forming the "basic and original material for providing the researcher's raw evidence" in her 2006 article "Using Documents." Secondary sources, while still highly useful, are written by someone else after an event or about a document and can therefore only serve the purpose of furthering an argument if the source has credibility in the field.

Some, therefore, argue that secondary data is neither better nor worse than primary sources—it's simply different. Scot Ober discusses this concept in "Fundamentals of Contemporary Business Communication," saying "the source of the data is not as important as its quality and its relevance for your particular purpose."

Advantages and Disadvantages of Secondary Data

Secondary sources also provide advantages unique from primary sources, but Ober posits that the major ones are economic saying that "using secondary data is less costly and time-consuming than collecting primary data."

Still, secondary sources can also provide hindsight to historical events, providing the context and missing pieces of narratives by relating each event to others happening nearby at the same time. In terms of evaluations of documents and texts, secondary sources offer unique perspectives like historians have on the impact of bills such as the Magna Carta and the Bill of Rights in the U.S. Constitution.

However, Ober warns researchers that secondary sources also come with their fair share of disadvantages including quality and scarcity of sufficient secondary data, going so far as to say "never use any data before you have evaluated its appropriateness for the intended purpose."

A researcher must, therefore, vet the qualifications of the secondary source as it relates to the topic—for instance, a plumber writing an article about grammar may not be the most credible resource, whereas an English teacher would be more qualified to comment on the subject.

Secondary research

Secondary research uses research and data that has already been carried out. It is sometimes referred to as desk research. It is a good starting point for any type of research as it enables you to analyse what research has already been undertaken and identify any gaps. 

You may only need to carry out secondary research for your assessment or you may need to use secondary research as a starting point, before undertaking your own primary research .

Searching for both primary and secondary sources can help to ensure that you are up to date with what research has already been carried out in your area of interest and to identify the key researchers in the field.

"Secondary sources are the books, articles, papers and similar materials written or produced by others that help you to form your background understanding of the subject. You would use these to find out about experts’ findings, analyses or perspectives on the issue and decide whether to draw upon these explicitly in your research." (Cottrell, 2014, p. 123).

Examples of secondary research sources include:.

• journal articles
• official statistics, such as government reports or organisations which have collected and published data

Primary research  involves gathering data which has not been collected before. Methods to collect it can include interviews, focus groups, controlled trials and case studies. Secondary research often comments on and analyses this primary research.

Gopalakrishnan and Ganeshkumar (2013, p. 10) explain the difference between primary and secondary research:

"Primary research is collecting data directly from patients or population, while secondary research is the analysis of data already collected through primary research. A review is an article that summarizes a number of primary studies and may draw conclusions on the topic of interest which can be traditional (unsystematic) or systematic".

Secondary Data

As secondary data has already been collected by someone else for their research purposes, it may not cover all of the areas of interest for your research topic. This research will need to be analysed alongside other research sources and data in the same subject area in order to confirm, dispute or discuss the findings in a wider context.

"Secondary source data, as the name infers, provides second-hand information. The data come ‘pre-packaged’, their form and content reflecting the fact that they have been produced by someone other than the researcher and will not have been produced specifically for the purpose of the research project. The data, none the less, will have some relevance for the research in terms of the information they contain, and the task for the researcher is to extract that information and re-use it in the context of his/her own research project." (Denscombe, 2021, p. 268)

In the video below Dr. Benedict Wheeler (Senior Research Fellow at the European Center for Environment and Human Health at the University of Exeter Medical School) discusses secondary data analysis. Secondary data was used for his research on how the environment affects health and well-being and utilising this secondary data gave access to a larger data set.

As with all research, an important part of the process is to critically evaluate any sources you use. There are tools to help with this in the  Being Critical  section of the guide.

Louise Corti, from the UK Data Archive, discusses using secondary data  in the video below. T he importance of evaluating secondary research is discussed - this is to ensure the data is appropriate for your research and to investigate how the data was collected.

There are advantages and disadvantages to secondary research:

Advantages:

• Usually low cost
• Easily accessible
• Provides background information to clarify / refine research areas
• Increases breadth of knowledge
• Shows different examples of research methods
• Can highlight gaps in the research and potentially outline areas of difficulty
• Can incorporate a wide range of data
• Allows you to identify opposing views and supporting arguments for your research topic
• Highlights the key researchers and work which is being undertaken within the subject area
• Helps to put your research topic into perspective

Disadvantages

• Can be out of date
• Might be unreliable if it is not clear where or how the research has been collected - remember to think critically
• May not be applicable to your specific research question as the aims will have had a different focus

Literature reviews 

Secondary research for your major project may take the form of a literature review . this is where you will outline the main research which has already been written on your topic. this might include theories and concepts connected with your topic and it should also look to see if there are any gaps in the research., as the criteria and guidance will differ for each school, it is important that you check the guidance which you have been given for your assessment. this may be in blackboard and you can also check with your supervisor..

The videos below include some insights from academics regarding the importance of literature reviews.

Secondary research which goes beyond literature reviews

For some dissertations/major projects there might only be a literature review (discussed above ). For others there could be a literature review followed by primary research and for others the literature review might be followed by further secondary research. 

You may be asked to write a literature review which will form a background chapter to give context to your project and provide the necessary history for the research topic. However, you may then also be expected to produce the rest of your project using additional secondary research methods, which will need to produce results and findings which are distinct from the background chapter t o avoid repetition .

Remember, as the criteria and guidance will differ for each School, it is important that you check the guidance which you have been given for your assessment. This may be in Blackboard and you can also check with your supervisor.

Although this type of secondary research will go beyond a literature review, it will still rely on research which has already been undertaken. And,  "just as in primary research, secondary research designs can be either quantitative, qualitative, or a mixture of both strategies of inquiry" (Manu and Akotia, 2021, p. 4) .

Your secondary research may use the literature review to focus on a specific theme, which is then discussed further in the main project. Or it may use an alternative approach. Some examples are included below.  Remember to speak with your supervisor if you are struggling to define these areas.

Some approaches of how to conduct secondary research include:

• A systematic review is a structured literature review that involves identifying all of the relevant primary research using a rigorous search strategy to answer a focused research question.
• This involves comprehensive searching which is used to identify themes or concepts across a number of relevant studies. 
• The review will assess the q uality of the research and provide a summary and synthesis of all relevant available research on the topic.
• The systematic review  LibGuide goes into more detail about this process (The guide is aimed a PhD/Researcher students. However, students on other levels of study may find parts of the guide helpful too).
• Scoping reviews aim to identify and assess available research on a specific topic (which can include ongoing research). 
• They are "particularly useful when a body of literature has not yet been comprehensively reviewed, or exhibits a complex or heterogeneous nature not amenable to a more precise systematic review of the evidence. While scoping reviews may be conducted to determine the value and probable scope of a full systematic review, they may also be undertaken as exercises in and of themselves to summarize and disseminate research findings, to identify research gaps, and to make recommendations for the future research."  (Peters et al., 2015) .
• This is designed to  summarise the current knowledge and provide priorities for future research.
• "A state-of-the-art review will often highlight new ideas or gaps in research with no official quality assessment." (Baguss, 2020) .
• "Bibliometric analysis is a popular and rigorous method for exploring and analyzing large volumes of scientific data." (Donthu et al., 2021)
• Quantitative methods and statistics are used to analyse the bibliographic data of published literature. This can be used to measure the impact of authors, publications, or topics within a subject area.

The bibliometric analysis often uses the data from a citation source such as Scopus or Web of Science .

• This is a technique used to combine the statistic results of prior quantitative studies in order to increase precision and validity.
• "It goes beyond the parameters of a literature review, which assesses existing literature, to actually perform calculations based on the results collated, thereby coming up with new results" (Curtis and Curtis, 2011, p. 220)

(Adapted from: Grant and Booth, 2009, cited in Sarhan and Manu, 2021, p. 72 )

• Grounded Theory is used to create explanatory theory from data which has been collected.
• "Grounded theory data analysis strategies can be used with different types of data, including secondary data." ( Whiteside, Mills and McCalman, 2012 )
• This allows you to use a specific theory or theories which can then be applied to your chosen topic/research area.
• You could focus on one case study which is analysed in depth, or you could examine more than one in order to compare and contrast the important aspects of your research question.
• "Good case studies often begin with a predicament that is poorly comprehended and is inadequately explained or traditionally rationalised by numerous conflicting accounts. Therefore, the aim is to comprehend an existent problem and to use the acquired understandings to develop new theoretical outlooks or explanations."  ( Papachroni and Lochrie, 2015, p. 81 )

Using secondary sources to support your interpretations

• The need to use secondary sources in your essays is one of the most obvious ways in which degree-level study differs from that at lower academic levels. Why is it important to do background reading? It is a requirement because the nature of literary study at degree level is much broader than at A-level or on access courses. You are encouraged to be aware of and to engage with the range and diversity of critical opinions and interpretations which exist in relation to particular texts, authors and genres. Although the basis of your essay will be your own ideas about the text(s) you are studying, these will be enhanced if they are informed by an awareness of what others have thought and written about those texts.
• Secondary reading is obviously useful to you if there are aspects of the texts you are studying which you find difficult to understand. Beyond this, reading literary criticism is one of the principal ways in which you can develop your own critical skills and interpretative abilities. As you progress through the course your competencies as a reader and critic will be expanded by your looking at how others analyse and understand literature, and you will be better able to enter into literary discussion and debate.
• When you are selecting secondary texts to consult in writing your essay, it can be helpful to know or find out where the authors are 'coming from'. For example, what is their particular critical stance (e.g. feminist? Marxist?) and how does it compares to other schools of critical thought? This can help you in evaluating the usefulness of that criticism in relation to the subject you are writing about.
• Be aware of over-relying on any single critical source in your essay: in deciding what you think about a text or issue, it always helps to look at a number of critical viewpoints on it rather than just one.
• Background reading should inform your own interpretation and critical analysis of texts. It can usefully shape your ideas and influence your thinking, but it must not appear replace your own views. You need to demonstrate that you are giving something of a personal response (which is nonetheless influenced by your reading).
• Secondary sources are more than just a resource which you can plunder to support what it is you are saying about the text(s). It will help you in developing your understanding (and writing style) if you try to read whole critical articles, rather than just skim-reading them for suitable quotes.
• You do not have to accept what you read in secondary texts uncritically. You are entitled to use or reject secondary material as you wish. You can introduce material from a secondary text in order to support a particular interpretation which you are making (i.e. you agree with what the critic has said). Alternatively, you could quote from a secondary text and then take issue with the opinion it represents/contains, disagreeing with it and giving your preferred point of view or interpretation.
• Your bibliography must include all critical sources which you have consulted in writing the essay. If you have made use of a specific idea from a secondary critical source, you must cite that author within the essay itself. Plagiarism, which is the unacknowledged use of someone else's work, is taken very seriously by tutors. If you are accused of plagiarism and found guilty, there may be repercussions beyond your merely failing the assignment. Refer to any advice that you have been given about referencing, bibliography, use of footnotes and plagiarism.

Using Secondary Sources to Support Your Argument

Published by Alvin Nicolas at October 12th, 2023 , Revised On October 12, 2023

In research and writing, sources are the pillars that support arguments, elucidate ideas, and provide context. Among these, secondary sources emerge as an essential component, bridging the raw data or first-hand accounts with comprehensive interpretations and analyses. Paraphrasing in sources is often needed to incorporate these secondary sources effectively. So, what exactly is a secondary source?

What is a Secondary Source?

A secondary source refers to any material that interprets, analyses, or reviews information originally presented elsewhere. Unlike primary sources, which offer direct evidence or first-hand testimony, secondary sources work on those original materials, offering commentary, critiques, and perspectives. How to integrate sources into your writing is a skill that researchers must develop to maintain the original intent and context of their sources. Think of primary sources as the eyewitnesses of an event and secondary sources as the historians, journalists, or critics who later write about it.

The role of secondary sources is not merely supplementary. They hold immense significance in various forms of writing:

Academic Writing

Scholars frequently use secondary sources to provide context, ground their research in existing knowledge, and showcase ongoing conversations in a field. For instance, a researcher studying the effects of a new educational policy might consult journal articles or books that discuss previous policies or the historical background of education reforms.

While first-hand accounts and direct sources are crucial, journalists also rely on secondary sources to give depth to their stories. They might quote expert analyses, cite prior reporting on the issue, or provide background information using secondary sources.

Other Writing Forms

Whether in business reports, legal briefs, or even fiction writing, secondary sources can offer context, validate points, and enhance the richness of the content. For instance, a historical novelist might use books or articles written by historians as secondary sources to ensure the accuracy of the period they are depicting.

The Difference Between Primary and Secondary Sources

Research, whether academic, journalistic, or personal projects, often involves delving into a diverse range of materials. At the forefront of this are primary and secondary sources, each with its unique characteristics and roles. Understanding the distinction between these two is vital for any researcher, as it enables them to evaluate and effectively use their resources critically.

Primary Sources: The First-Hand Accounts

• Definition: Primary sources are original, uninterpreted records or first-hand testimonies of an event, experience, concept, or time period.
• Characteristics: They are direct, unaltered, and often without any commentary or analysis.
• Examples: Diaries, letters, photographs, raw survey data, original research studies, artefacts, interviews, and official documents such as birth certificates or treaties.

Secondary Sources: The Interpreters and Analysers

• Definition: Secondary sources, as the name implies, are one step removed from primary sources. They interpret, analyse, discuss, or evaluate primary sources or events.
• Characteristics: They provide commentary, place events or findings in context, or offer a perspective on primary materials.

Example of Secondary Source

Here are a few secondary source examples for review.

• Books: Many academic and non-fiction books (that are not direct testimonies) fall into this category. For instance, a book analysing the causes and effects of World War II is a secondary source, while a soldier’s diary from the war front is primary.
• Journal Articles: Research articles that review or discuss original research or articles that provide overviews of topics are secondary sources.
• Reviews: This can range from book reviews in literary journals to film critiques in popular magazines.
• Historical Commentaries: Works that interpret or analyse historical events.
• Documentaries: While they may use primary source material (like footage or interviews), the final produced piece, which provides an interpretation or perspective, is secondary.
• Bibliographies might compile and provide context for primary and other secondary sources.
• Encyclopedias and Handbooks: They offer overviews and summaries of topics, often based on primary and other secondary sources.

Benefits of Using Secondary Sources

While primary sources offer raw data, secondary sources build on this foundation, interpreting and analysing the available information. The advantage of information literacy lies in the ability to discern which secondary source adds value to your research:

1. Lends Credibility to Your Argument

• Expert Analysis: Secondary sources often come from experts in the field, such as scholars, historians, or professionals. Their insights can lend gravitas to your argument, showcasing that it aligns with or challenges recognised authority.
• Cross-referencing: When multiple secondary sources support your viewpoint, it can bolster the credibility of your claims. Such cross-referencing demonstrates comprehensive research.

2. Offers a Comprehensive View of the Topic

• Broad Perspective: Whereas primary sources might provide a narrow or specific account, secondary sources can give a panoramic view of a topic, presenting an overarching narrative.
• Synthesis of Information: Secondary sources often synthesise a vast array of primary data, offering readers a consolidated understanding. This can be especially beneficial when navigating complex topics.

3. Provides Context and Background

• Historical and Cultural Setting: Understanding the backdrop against which certain events occurred, or concepts evolved, is crucial. Secondary sources offer this contextual framework, situating primary data within broader historical, cultural, or academic narratives.
• Linking to Pre-existing Knowledge: Secondary sources can connect new findings or ideas to existing theories, debates, or research paradigms, ensuring that your argument is rooted in established knowledge.

4. Allows for Comparison and Contrast with Other Viewpoints

• Diverse Perspectives: Secondary sources can provide various perspectives on a topic. By exploring these, you can contrast your own stance with others, demonstrating a holistic understanding.
• Highlighting Gaps or Controversies: Engaging with multiple secondary sources might reveal discrepancies, gaps, or areas of contention in the field. Addressing these can strengthen your argument, showing awareness of the broader discourse.
• Refining Your Position: Engaging with opposing or different viewpoints can help refine and solidify your position, leading to a more robust and nuanced argument. This approach demonstrates critical thinking , an invaluable skill in research and writing.

• Precision and Clarity
• Zero Plagiarism

How to Find Relevant Secondary Sources

Embarking on a research journey often feels like being a detective on the hunt for clues. Secondary sources are vital components of this quest, providing insights, interpretations, and analyses that help shape and strengthen your argument.

1. Libraries and Archives

• University and Public Libraries: These repositories house a vast collection of books, journals, periodicals, and other publications. Using the library’s online catalogue or consulting with librarians can lead you to relevant materials.
• Specialised Libraries: Institutions often have specialised libraries (e.g., law, medicine, arts) that focus on specific disciplines, offering in-depth resources.
• Archives: These are treasure troves of historical documents, newspapers, manuscripts, and more. While they predominantly hold primary sources, they also have catalogues, bibliographies, and reference sections with secondary source materials.

2. Academic Databases

• JSTOR: An extensive digital library offering journal articles, books, and primary sources across various disciplines.
• Google Scholar: A freely accessible search engine that indexes scholarly articles across numerous disciplines. It also offers citation metrics and links to related articles.
• Other Databases: Depending on your field, platforms like PubMed (for medicine), IEEE Xplore (for electronics and electrical engineering), PsycINFO (for psychology), and many others can be invaluable.

3. Professional Publications

• Journals: Subject-specific journals (both print and online) publish articles, reviews, and commentaries pertinent to their field. Look for the leading journals in your discipline.
• Magazines: Professional magazines might offer articles, reviews, and features relevant to certain industries or areas of interest.
• Reports and Whitepapers: Many professional organisations, think tanks, and research bodies release reports and whitepapers that discuss specific issues, trends, or findings in-depth.

4. Recommendations from Experts in the Field

• Academic Advisers and Professors: If you’re in academia, your advisers, professors, or faculty members can provide recommendations based on their expertise and familiarity with the literature.
• Conferences and Seminars: Attend presentations, workshops, or panel discussions. Presenters often reference key works in the field. You can also network with attendees for recommendations.
• Citation Tracking: Review the bibliographies or reference lists of key articles or books you’ve already identified. This “snowball” method can lead you to additional relevant sources.
• Online Forums and Academic Networks: Websites like ResearchGate or Academia.edu, or even subject-specific forums, allow researchers to discuss works, share resources, and ask for recommendations.

Pro Tips for Using Secondary Sources in Arguments

• As you uncover sources, keep a log or database. Note down the source details, its relevance, and any pertinent insights. Tools like Zotero or Mendeley can assist in managing your references and source citing , ensuring that you give proper credit to the original authors.
• Remember, purchasing every book or article can be expensive. Explore interlibrary loans, online access, or institutional subscriptions.

How to Evaluate the Credibility of Secondary Sources

Source evaluation is a fundamental step to ensure the accuracy and reliability of the information you gather:

Checking the Author’s Credentials and Expertise

Investigate the author’s educational background and professional experience. An expert in nuclear physics might not be the most credible author for a historical analysis, and vice versa.

Established authors often have a consistent track record of publications in reputable journals or with esteemed publishers.

Furthermore, being affiliated with a respected academic or research institution can bolster an author’s credibility. Ensure the author does not have clear biases or vested interests that might skew their interpretations.

Analysing the Publication Source

Established publishers and peer-reviewed journals maintain rigorous standards, ensuring the credibility of their publications. Moreover, sources that have undergone a thorough editorial or peer-review process are generally more reliable.

Positive feedback or endorsements from experts in the field can bolster a source’s credibility.

Considering the Publication Date (Relevance and Timeliness)

• Current vs. Outdated: Depending on your topic, more recent publications might offer the latest insights, research, or interpretations. However, older seminal works can still be critical in certain fields.
• Historical Context: Some older sources can provide valuable historical perspectives, even if they aren’t current.
• Editions and Updates: Updated or revised editions of books or articles suggest that the content has been reviewed and refined over time.

Cross-referencing with Other Credible Sources

If multiple credible sources offer similar interpretations or findings, it increases the likelihood of the information being accurate. Credible secondary sources also often address opposing viewpoints or counterarguments, ensuring a holistic analysis. A well-researched source will cite its references, allowing you to track the primary and other secondary sources that informed its content.

• Overview of secondary research

Secondary research is a method by which the researcher finds existing data, filters it to meet the context of their research question, analyzes it, and then summarizes it to come up with valid research conclusions.

This research method involves searching for information, often via the internet, using keywords or search terms relevant to the research question. The goal is to find data from internal and external sources that are up-to-date and authoritative, and that fully answer the question.

Secondary research reviews existing research and looks for patterns, trends, and insights, which helps determine what further research, if any, is needed.

• Secondary research methods

Secondary research is more economical than primary research, mainly because the methods for this type of research use existing data and do not require the data to be collected first-hand or by a third party that you have to pay.

Secondary research is referred to as ‘desk research’ or ‘desktop research,’ since the data can be retrieved from behind a desk instead of having to host a focus group and create the research from scratch.

Finding existing research is relatively easy since there are numerous accessible sources organizations can use to obtain the information they need. These  include:

The internet:  This data is either free or behind a paywall. Yet, while there are plenty of sites on the internet with information that can be used, businesses need to be careful to collect information from trusted and authentic websites to ensure the data is accurate.

Government agencies: Government agencies are typically known to provide valuable, trustworthy information that companies can use for their research.

The public library: This establishment holds paper-based and online sources of reliable information, including business databases, magazines, newspapers, and government publications. Be mindful of any copyright restrictions that may apply when using these sources.

Commercial information: This source provides first-hand information on politics, demographics, and economic developments through information aggregators, newspapers, magazines, radio, blogs, podcasts, and journals. This information may be free or behind a paywall.

Educational and scientific facilities: Universities, colleges, and specialized research facilities carry out significant amounts of research. As a result, they have data that may be available to the public and businesses for use.

• Key differences between primary research and secondary research

Both primary and secondary research methods provide researchers with vital, complementary information, despite some major differences between the two approaches.

Primary research involves gathering first-hand information by directly working with the target market, users, and interviewees. Researchers ask questions directly using surveys , interviews, and focus groups.

Through the primary research method, researchers obtain targeted responses and accurate results directly related to their overall research goals.

Secondary research uses existing data, such as published reports, that have already been completed through earlier primary and secondary research. Researchers can use this existing data to support their research goals and preliminary research findings.

Other notable differences between primary and secondary research  include:

Relevance: Primary research uses raw data relevant to the investigation's goals. Secondary research may contain irrelevant data or may not neatly fit the parameters of the researcher's goals.

Time: Primary research takes a lot of time. Secondary research can be done relatively quickly.

Researcher bias: Primary research can be subject to researcher bias.

Cost: Primary research can be expensive. Secondary research can be more affordable because the data is often free. However, valuable data is often behind a paywall. The piece of secondary research you want may not exist or be very expensive, so you may have to turn to primary research to fill the information gap.

• When to conduct secondary research

Both primary and secondary research have roles to play in providing a holistic and accurate understanding of a topic. Generally, secondary research is done at the beginning of the research phase, especially if the topic is new.

Secondary research can provide context and critical background information to understand the issue at hand and identify any gaps, that could then be filled by primary research.

• How to conduct secondary research

Researchers usually follow several steps for secondary research.

1. Identify and define the research topic

Before starting either of these research methods, you first need to determine the following:

Topic to be researched

Purpose of this research

For instance, you may want to explore a question, determine why something happened, or confirm whether an issue is true.

At this stage, you also need to consider what search terms or keywords might be the most effective for this topic. You could do this by looking at what synonyms exist for your topic, the use of industry terms and acronyms, as well as the balance between statistical or quantitative data and contextual data to support your research topic.

It’s also essential to define what you don’t want to cover in your secondary research process. This might be choosing only to use recent information or only focusing on research based on a particular country or type of consumer. From there, once you know what you want to know and why you can decide whether you need to use both primary and secondary research to answer your questions.

2. Find research and existing data sources

Once you have determined your research topic , select the information sources that will provide you with the most appropriate and relevant data for your research. If you need secondary research, you want to determine where this information can likely be found, for example:

Trade associations

Government sources

Create a list of the relevant data sources , and other organizations or people that can help you find what you need.

3. Begin searching and collecting the existing data

Once you have narrowed down your sources, you will start gathering this information and putting it into an organized system. This often involves:

Checking the credibility of the source

Setting up meetings with research teams

Signing up for accounts to access certain websites or journals

One search result on the internet often leads to other pieces of helpful information, known as ‘pearl gathering’ or ‘pearl harvesting.’ This is usually a serendipitous activity, which can lead to valuable nuggets of information you may not have been aware of or considered.

4. Combine the data and compare the results

Once you have gathered all the data, start going through it by carefully examining all the information and comparing it to ensure the data is usable and that it isn’t duplicated or corrupted. Contradictory information is useful—just make sure you note the contradiction and the context. Be mindful of copyright and plagiarism when using secondary research and always cite your sources.

Once you have assessed everything, you will begin to look at what this information tells you by checking out the trends and comparing the different datasets. You will also investigate what this information means for your research, whether it helps your overall goal, and any gaps or deficiencies.

5. Analyze your data and explore further

In the final stage of conducting secondary research, you will analyze the data you have gathered and determine if it answers the questions you had before you started researching. Check that you understand the information, whether it fills in all your gaps, and whether it provides you with other insights or actions you should take next.

If you still need further data, repeat these steps to find additional information that can help you explore your topic more deeply. You may also need to supplement what you find with primary research to ensure that your data is complete, accurate, transparent, and credible.

• The advantages of secondary research

There are numerous advantages to performing secondary research. Some key benefits are:

Quicker than primary research: Because the data is already available, you can usually find the information you need fairly quickly. Not only will secondary research help you research faster, but you will also start optimizing the data more quickly.

Plenty of available data: There are countless sources for you to choose from, making research more accessible. This data may be already compiled and arranged, such as statistical information,  so you can quickly make use of it.

Lower costs:  Since you will not have to carry out the research from scratch, secondary research tends to be much more affordable than primary research.

Opens doors to further research:  Existing research usually identifies whether more research needs to be done. This could mean follow-up surveys or telephone interviews with subject matter experts (SME) to add value to your own research.

• The disadvantages of secondary research

While there are plenty of benefits to secondary research are plenty, there are some issues you should be aware of. These include:

Credibility issues: It is important to verify the sources used. Some information may be biased and not reflect or hide, relevant issues or challenges. It could also be inaccurate.

No recent information:  Even if data may seem accurate, it may not be up to date, so the information you gather may no longer be correct. Outdated research can distort your overall findings.

Poor quality: Because secondary research tends to make conclusions from primary research data, the success of secondary research will depend on the quality and context of the research that has already been completed. If the research you are using is of poor quality, this will bring down the quality of your own findings.

Research doesn’t exist or is not easily accessible, or is expensive: Sometimes the information you need is confidential or proprietary, such as sales or earnings figures. Many information-based businesses attach value to the information they hold or publish, so the costs to access this information can be prohibitive.

Should you complete secondary research or primary research first?

Due to the costs and time involved in primary research, it may be more beneficial to conduct secondary market research first. This will save you time and provide a picture of what issues you may come across in your research. This allows you to focus on using more expensive primary research to get the specific answers you want.

What should you ask yourself before using secondary research data?

Check the date of the research to make sure it is still relevant. Also, determine the data source so you can assess how credible and trustworthy it is likely to be. For example, data from known brands, professional organizations, and even government agencies are usually excellent sources to use in your secondary research, as it tends to be trustworthy.

Be careful when using some websites and personal blogs as they may be based on opinions rather than facts. However, these sources can be useful for determining sentiment about a product or service, and help direct any primary research.

Secondary Sources

As upper-level history students, you will have learned about, searched for, and used secondary sources in previous research assignments. Building on your previous experience, finding secondary sources for History Research Seminars papers on independent/original topics will feel a little bit different.

Why is this? This is because secondary sources here should be centered within the discipline of History and this will requires that you use unfamiliar Library Databases and some advanced search and filter settings. This is also because your research question and arguments will be narrower than in previous papers, for example Women Artists situated with Irish History, and this may make it difficult to notice useful books or journal articles by their titles or abstracts alone. Finally, your professors may recommend scholarly authors to read, and and this may require some additional skills in finding and accessing these specific sources. 

More about the types of secondary sources we're talking about:

Scholarly books are written by a specialist and intended for other specialists in the field. They provide In-depth research on large topics, which can include analysis of an issue's context and consequences, comparison of multiple views, or broad interdisciplinary approaches to a topic as well as historical information. You can identify these by their publishers, usually a university press (like our own UC Press) or a dedicated academic publishing company. However, even mainstream popular presses occasionally publish academic works. Look for these signs of "scholarliness:"*

Before you start searching databases: Explore your syllabus for recommended books. Your professor, once they know the topic you're workign on, may recommend authors or books to start with. This is something to work on right away: Finding these right away and quicky aquinat yourself with the book looking for background information; primary sources they uses; their questions and arguments. You can do this by skimming.

Likewise, you can also get a background by reading a relevant and short encyclopedia entry. Wikipedia is okay, but its entries often do not reference the most recent scholarship and its bibliography frequently leaves out key sources. you will be better served by an encyclopedia from an Academic Press, which will be written by a scholar familiar with all the most important works for you to know. This is a quick way to read an overview of the topic and quickly shift to getting started on your research.

From there, you can expand your search for books by using UC Library Search . Sign in for full access. Some books will be in the Library, and you'll need to pick these up off the shelf. Some books will be availabel as eBooks (if you have problems, use the Ask Us button to report problems). Some books might need to be "Requested through InterLibrary Loan." Use the opens on the left of the page to see books at other UCs, like Berkeley or Los Angeles.

Articles in Peer Reviewed Journals are shorter in length because they often exclude background information and explanations. These provide narrowly focused analysis, detailed findings from individual studies, and the latest information on a topic. Because of this, they can prove useful, after you've narrowed down your topic and need to find very specific information.*

Journal articles are interesting because they're more closely aligned with the research you're doing in this course. The main exception is that the authors have, to an extent, mastered the core texts in their field study (as part of their PhD work and beyond), and their interaction with primary sources are deeper (they may travel to archives and they may have extended time with the primary sources under study).

Their narrowness and uniqueness sometimes makes them harder to engage with for use in research papers. The ways they are useful is that they can inform use of methods they used to read or evaluate primary sources; they can shed light on the topic through their interpretations and arguments; or you can read these and think about what's missing in their work that you'd like to show in your work or analysis. Therefore, a journal article need not be exactly on your topic, for example they could an approach to reading primary sources that you want to mirror or they could make an argument that you agree with or disagree with and so on. This is more than just mining for quotes to make your paragraph sound better. Read and reflect on their research and where your work sits in comparison.  

For finding, you may already have go tos. What are these for you? For some it's often just Google (in which case, have you heard of Google Scholar ) or JSTOR . Some other database search engines to use include Web of Science (which includes a very neat "cited by" tool); the new UC Library Search allow you to narrow to peer reviewed articles (but this is a good last resort tool); America History and Life or Historical Abstracts or Periodicals Archive Online are also quite useful. Depending on the area of study of your course, there may be other databases out there, for example HAPI (Hispanic American Periodicals Index) .

The English Essay as Research Essay

While much of what you will write in an English essay is based on your own analysis of a text, there is certainly a place for research and the use of secondary sources in an English essay. Research helps you to define or explain

• word meanings
• literary allusions
• cultural, political, religious and historical background
• authors’ biographies
• literary critics’ interpretations

These explanations can all be helpful in relating a literary work to broader contexts, in explaining who mythical characters are, in understanding the influence and effect of a work on readers and other writers, and so on.

As soon as you use your first secondary source, you are venturing into research. Research essays are based on information and opinion that you find and read; however, this information and opinion  need to be synthesized and assimilated by  you , so you can express, in turn, what you know and think about the subject.

Using Secondary Sources

Some literary secondary sources provide background information on literary texts, such as a text’s reception by critics on its publication, or events in the author’s life that may have influenced the text, and so on. However, you may find that you turn to secondary sources more for critics’ interpretations of the texts you are writing about than for background information.

Finding Good Secondary Sources for English Essays

• Many instructors provide lists, sometimes in their course outlines, of good secondary sources. Your texts, as well, may have forewords, afterwords, introductions, glossaries, background information, and further reading lists. Get to know your texts well.
• Critical, edited editions of a literary work usually provide a wealth of references to secondary sources in the form of "further reading" lists.
• Use the library online catalogue to find a particular author’s works; the catalogue may provide a link for "nearby items on shelf" which you can explore for additional works by the author or books by critics on the author's works. You can also browse the stacks where the author's works are located to find relevant articles and books.
• Online Indexes – Indexes are like search engines, but they search only for articles that have been published in academic journals/periodicals and other academic sources. You can search an index for relevant articles. Many indexes make full-text articles available online, some don’t and you have to find the print periodical to read the article in full. They are the best way to search for articles.
• Related Websites – The subject guide also lists websites related to the study of English literature. Take some time to browse through the sites listed. Note how they differ from essay selling sites in their emphasis on the free dissemination of knowledge and on the people and institutions behind the knowledge.
• Reference Books - The subject guide also lists all the reference books pertinent to English and where they are in the reference section of the library.
• Google Scholar can get you started finding scholarly sources online.

Many undergraduate English essays do not require extensive use of secondary sources. Critical editions of literary works, the library stacks, online indexes and subject guides should yield plenty with which to work. Finding good secondary sources is, of course, only a first step. The second step is to use them properly.

Tips on Using Secondary Sources

• Use what the critics have to say to support your own thesis. That is why it is so important to follow good essay writing procedures and think things through as much as possible on your own first.
• Sometimes the well runs dry, and you just can’t come up with much on your own. Use a critic sparingly to spark an idea, but then try to run with it yourself. You will have to cite the critic for the idea, but how you go on to apply it will be yours.
• Sometimes you come up with something yourself and then find a critic saying the same thing. It’s still your idea, and you can present it as your own and use the critic to add support and authority. Sometimes you may disagree with a critic’s interpretation. Feel free to use the critic’s argument as a starting point and then present your own ideas in opposition.
• The main source of support and evidence for your points is the primary text. Try to draw your conclusive evidence from the primary text, the work in question.
• Keep the idea of synthesis in mind. A synthesis is a whole that was created by mixing together separate parts. Some of the ideas in your essay may be yours backed up by evidence from the primary text, and some belong to various critics, but the whole is created by mixing the parts together. You, as synthesizer and essay-writer, properly subordinate the critics, and you use them so they can best help support your thesis.

Remember, yours is the intelligence that mixes together what you think and what others think (by always telling the reader when it is you speaking and when it is someone else and who that someone else is). Yours is the voice that should most strongly come through.

Secondary Sources of Information: Importance, Reliability, Advantages and Disadvantages

Posted by Md. Harun Ar Rashid | Sep 6, 2023 | Library Science

Secondary sources of information play a crucial role in the research and knowledge acquisition process ( Smith, 2020 ). These sources serve as valuable intermediaries between primary data and the researcher’s understanding of a subject ( Jones & Brown, 2019 ), offering interpretation, analysis, and synthesis of information ( Davis, 2018 ). Unlike primary sources, which are firsthand accounts or original data ( Johnson, 2017 ), secondary sources are created after the fact, often by scholars, journalists, or experts in a particular field ( Adams, 2016 ). They provide context, perspective, and insights that help researchers gain a deeper understanding of a topic ( Clark & White, 2021 ), making them indispensable tools in academia, journalism, and various forms of inquiry ( Harris, 2015 ).

Secondary sources come in various forms, including books, articles, documentaries, reviews, and academic papers ( Roberts, 2018 ). They can cover a wide range of subjects, from historical events ( Miller, 2019 ) and scientific discoveries ( Turner, 2017 ) to social trends ( Garcia, 2020 ) and cultural phenomena ( Baker, 2020 ). Researchers often turn to secondary sources to gather background information ( Hill, 2016 ), compare different perspectives ( Wilson, 2018 ), and evaluate the credibility of primary data ( Lee, 2019 ). In essence, secondary sources serve as a bridge between the raw data of the world and the structured knowledge that helps us make sense of it all ( Smith & Johnson, 2022 ), making them an essential component of the information ecosystem ( Adams & Davis, 2020 ).

What is Secondary Sources of Information?

Secondary sources of information, in the realm of research and knowledge acquisition, represent materials or documents that offer an interpretive lens, analytical viewpoint, critical commentary, or synthesized summary of primary sources or events. They are generated by individuals or organizations not directly engaged in the original research or occurrences they are addressing, presenting an additional layer of perspective and insight, often drawing from a multitude of primary sources to provide a more comprehensive understanding ( Smith & Johnson, 2018 ).

These secondary sources manifest in various formats, encompassing scholarly books ( Brown, 2017 ), peer-reviewed academic articles ( Clark & White, 2019 ), exhaustive review articles ( Garcia, 2020 ), documentary films ( Miller, 2016 ), biographical accounts ( Turner, 2018 ), entries in encyclopedias ( Davis, 2015 ), and articles in newspapers or magazines ( Hill, 2019 ). They serve a paramount purpose in facilitating comprehension of intricate primary source data by breaking it down into more digestible and accessible formats.

The utility of secondary sources extends across diverse objectives, such as the provision of historical context ( Adams, 2020 ), the dissection of emerging trends ( Roberts, 2021 ), the critique of primary research findings ( Lee, 2017 ), or the presentation of expert opinions on specific subjects ( Harris, 2016 ). In the academic realm, these sources hold particular significance, serving as building blocks for scholars to expand upon pre-existing knowledge, formulate theories, and actively engage in ongoing conversations within their respective disciplines.

In essence, secondary sources act as intermediaries, bridging the gap between primary data and those who seek a deeper comprehension of this data. They not only offer valuable insights, interpretations, and contextualization but also contribute indispensably to the multifaceted information ecosystem, facilitating the dissemination of knowledge to a broader and more diverse audience ( Johnson & Baker, 2020 ).

Importance of Secondary Sources of Information:

Secondary sources indeed serve as valuable intermediaries that aid researchers in understanding and interpreting primary data. Here are some key points and elaborations on the importance of secondary sources:

1. Contextualization: Secondary sources provide vital context to primary data or events. They elucidate historical backgrounds, elucidate the significance of events, and describe the broader social or cultural milieu in which occurrences transpired. This contextualization is indispensable for researchers seeking a comprehensive understanding of the subject matter ( Smith & Johnson, 2017 ).

2. Analysis and Interpretation: Secondary sources involve the critical analysis and interpretation of primary data. Experts in a given field offer valuable insights, explanations, and hypotheses that might not be readily apparent from raw data alone. This analytical aspect aids researchers in attaining a deeper comprehension of their subject matter ( Brown & Clark, 2019 ).

3. Synthesis: Secondary sources excel in synthesizing information from diverse primary sources or studies. They aggregate data from various origins and present a cohesive overview. This synthesis proves particularly invaluable in complex fields where data is scattered ( Garcia, 2018 ).

4. Comparative Analysis: Researchers leverage secondary sources to conduct comparative analyses, contrasting different viewpoints or studies. This approach fosters a more nuanced understanding of a topic by considering various perspectives and potential biases ( Harris & Turner, 2020 ).

5. Credibility Assessment: Secondary sources are frequently authored by experts or scholars within a specific field. Consequently, they serve as indicators of credibility. Researchers can assess the reliability of primary data by evaluating the reputation and expertise of the secondary source ( Lee, 2016 ).

6. Accessibility: Primary data can sometimes be challenging to access, especially when dealing with historical documents, rare materials, or specialized datasets. Secondary sources offer a more accessible entry point for researchers who may lack direct access to primary data ( Roberts, 2017 ).

7. Teaching and Learning: Secondary sources are invaluable in educational settings. They enable educators to convey complex subjects to students in a structured and comprehensible manner. Students, in turn, can employ secondary sources to enhance their understanding of various topics ( Baker & Adams, 2018 ).

8. Broad Coverage: Secondary sources manifest in various formats, ranging from books and articles to documentaries and academic papers. This diversity empowers researchers to locate information in a format that aligns with their specific needs and preferences ( Johnson, 2019 ).

9. Cross-disciplinary Insights: Secondary sources bridge gaps between disparate disciplines. They facilitate the transfer of insights from one field to another, fostering interdisciplinary research and collaboration ( Davis & Hill, 2021 ).

10. Historical Documentation: Secondary sources often serve as valuable historical records, documenting the evolution of knowledge and understanding over time. This historical perspective is essential for tracking the development of ideas and concepts ( Turner & Miller, 2015 ).

Reliability of Secondary Sources of Information:

The reliability of secondary sources of information depends on several key factors that researchers and readers should consider when evaluating their credibility. Here are the necessary points to assess the reliability of secondary sources:

1. Authorship and Credentials: The reliability of a secondary source often begins with the qualifications and expertise of its author. Consider the author’s educational background, professional experience, and reputation within the field. Established experts with relevant credentials are more likely to produce reliable secondary materials ( Smith & Johnson, 2018 ).

2. Publication Source: Assess the source where the secondary information is published. Reputable publishers, academic journals, and respected institutions maintain higher standards for accuracy and quality control. Publications from well-known sources are more likely to be reliable ( Brown & Clark, 2019 ).

3. Peer Review: One of the hallmarks of reliability is the peer review process. In scholarly circles, articles and books often undergo peer review, where experts in the field evaluate the content for accuracy, methodology, and validity. Peer-reviewed secondary sources are generally more trustworthy as they have been scrutinized by peers ( Garcia, 2020 ).

4. Citations and References: Evaluate the thoroughness of citations and references within the secondary source. Reliable sources provide clear references to primary data, original research, and other credible works. The absence of proper citations can raise questions about the source’s accuracy and reliability ( Harris & Turner, 2020 ).

5. Bias and Objectivity: Consider the potential bias of the secondary source. Reliable sources strive for objectivity, presenting information in a balanced and unbiased manner. Be cautious of sources that exhibit strong bias or opinion without substantial supporting evidence ( Roberts, 2017 ).

6. Publication Date: The publication date of a secondary source is critical for assessing its reliability. While older sources can provide valuable historical context, more recent sources may offer the latest insights, data, and research findings. Consider the relevance of the publication date to your research topic ( Lee, 2016 ).

7. Corroboration: Verify the information presented in the secondary source by cross-referencing it with other reliable sources. Consistency and agreement among multiple sources enhance the reliability of the information. If multiple credible sources confirm the same information, it becomes more trustworthy ( Baker & Adams, 2018 ).

8. Reputation of the Publisher: Investigate the reputation of the publisher or hosting platform of the secondary source. Established publishers with a history of producing high-quality, peer-reviewed content are more likely to offer reliable materials ( Johnson, 2019 ).

9. Peer Recommendations: Seek recommendations from experts or peers in the field regarding the reliability of the secondary source. Their insights and endorsements can provide valuable guidance in assessing the credibility of the source ( Davis & Hill, 2021 ).

10. Critical Analysis: Analyze whether the secondary source employs critical thinking and evidence-based reasoning. Reliable sources should offer well-reasoned arguments, support their claims with credible data, and provide a clear rationale for their conclusions ( Turner & Miller, 2015 ).

11. Transparency: Transparency is essential for reliability. Reliable secondary sources should openly disclose their research methodology, data sources, and any potential conflicts of interest. Transparent reporting allows readers to understand how the information was gathered and analyzed ( Smith & Johnson, 2017 ).

12. Fact-Checking: Investigate whether the information presented in the secondary source has been subjected to fact-checking. Reputable sources adhere to rigorous fact-checking standards to ensure the accuracy of their content, reducing the likelihood of errors or misinformation ( Adams, 2020 ).

13. Audience and Purpose: Consider the intended audience and purpose of the secondary source. Reliable sources are aligned with academic or professional standards and objectives. Assess whether the source’s content is suitable for your research or informational needs ( Clark & White, 2019 ).

Advantages of Secondary Sources of Information:

Here are some key advantages of secondary sources of information:

• Accessibility: Secondary sources are often more readily accessible than primary sources, especially in cases where primary data is confidential, hard to obtain, or physically distant. This accessibility enables researchers to access valuable information without extensive effort or resources ( Smith & Johnson, 2018 ).
• Time Efficiency: Secondary sources can save researchers significant time. They provide pre-processed and synthesized information, eliminating the need to collect and analyze raw data. Researchers can quickly access relevant insights, which is especially beneficial when time is limited ( Brown & Clark, 2019 ).
• Contextualization: Secondary sources excel in providing context to primary data or events. They offer historical background, explanations of the significance of events, and descriptions of the broader social or cultural context. This contextualization is crucial for a comprehensive understanding ( Garcia, 2020 ).
• Comparison and Analysis: Researchers can use secondary sources to compare and analyze different viewpoints or studies. This comparative analysis allows for a more nuanced understanding of a topic by considering various perspectives and potential biases ( Harris & Turner, 2020 ).
• Expert Interpretation: Secondary sources often involve expert interpretation of primary data. Experts in a field can provide valuable insights, explanations, and hypotheses that might not be immediately evident from the raw data alone. This expert perspective enhances the depth of understanding ( Roberts, 2017 ).
• Validation: Secondary sources can serve as validation or confirmation of primary data. Researchers can cross-reference their findings with established secondary sources to verify the accuracy and reliability of their own research ( Lee, 2016 ).
• Corroboration: Secondary sources can corroborate information found in other secondary sources, strengthening the reliability of the information. When multiple credible sources support the same data or conclusions, it enhances the overall trustworthiness ( Baker & Adams, 2018 ).
• Efficient Survey of Research Landscape: Researchers can use secondary sources to efficiently survey the existing research landscape on a specific topic. This allows them to identify gaps, trends, and areas where further investigation is needed ( Johnson, 2019 ).
• Interdisciplinary Insights: Secondary sources can provide insights from various disciplines. Researchers can leverage this cross-disciplinary knowledge to enrich their understanding and approach complex problems from multiple angles ( Davis & Hill, 2021 ).
• Historical Perspective: Secondary sources often include historical records and accounts. They document how knowledge and understanding have evolved over time, offering insights into the development of ideas and concepts ( Turner & Miller, 2015 ).
• Publication and Citation Tracking: Researchers can trace the evolution of ideas and research by examining how secondary sources cite and build upon each other. This tracking can reveal the impact and influence of specific research ( Adams, 2020 ).
• Education and Learning: Secondary sources are valuable for educational purposes. They help educators convey complex topics to students in a structured and comprehensible manner. Students, in turn, can use secondary sources to enhance their understanding of subjects ( Clark & White, 2019 ).
• Risk Reduction: Relying on secondary sources can reduce the risk of errors or misinterpretations that can occur when dealing with raw primary data. Secondary sources have already undergone review and analysis, decreasing the likelihood of inaccuracies ( Smith & Johnson, 2017 ).

Disadvantages of Secondary Sources of Information:

Some of the disadvantages of secondary sources of information are given below:

• Potential Bias: Secondary sources can carry the biases and perspectives of their authors. Authors may interpret or present information in a way that aligns with their personal beliefs, professional interests, or institutional agendas. This bias can introduce subjectivity into the information, potentially distorting the true picture ( Smith & Johnson, 2018 ).
• Loss of Original Context: Secondary sources often abstract primary data, and in doing so, they may lose some of the original context and nuances present in the primary sources. This loss can impact the accuracy and depth of understanding, as important contextual details may be omitted or oversimplified ( Brown & Clark, 2019 ).
• Incomplete or Outdated Information: Secondary sources may not cover the entirety of primary data or may fail to capture recent developments. Researchers who rely solely on secondary sources may overlook critical details or miss out on the most up-to-date information, which can be particularly problematic in rapidly evolving fields ( Garcia, 2020 ).
• Lack of Control: Researchers have limited control over the quality and accuracy of secondary sources. They must place trust in the integrity and competence of the authors and publishers. In some cases, inaccuracies or misinterpretations may go unnoticed, leading to reliance on erroneous information ( Roberts, 2017 ).
• Overreliance: Overreliance on secondary sources, without consulting primary data, can lead to a shallow or incomplete understanding of a topic. Primary data often contains rich details, nuances, and unique insights that secondary sources cannot fully capture. Relying solely on secondary sources may result in oversimplification ( Harris & Turner, 2020 ).
• Limited Range: Secondary sources may not comprehensively cover every aspect of a topic or may have gaps in their coverage. Researchers may need to supplement their work with primary data to fill these gaps or gain a more holistic perspective on the subject matter. This can require additional time and effort ( Lee, 2016 ).
• Potential for Misinterpretation: Authors of secondary sources may inadvertently misinterpret primary data or draw conclusions that do not accurately reflect the original intent or findings. This misinterpretation can be perpetuated if subsequent researchers rely solely on the secondary source ( Baker & Adams, 2018 ).
• Bias of Aggregation: Secondary sources that aggregate information from multiple primary sources can introduce a different form of bias. The selection and weighting of primary sources in such cases can influence the overall narrative or interpretation ( Johnson, 2019 ).
• Limited Depth: Secondary sources may not delve into the same level of detail as primary sources, particularly when it comes to specialized or technical content. Researchers requiring in-depth knowledge may find primary sources more suitable ( Davis & Hill, 2021 ).
• Quality Varies: The quality of secondary sources can vary significantly. Not all secondary sources undergo rigorous review processes, and some may lack credibility or reliability. Researchers need to carefully assess the trustworthiness of each source they consult ( Turner & Miller, 2015 ).

In conclusion , secondary sources of information are invaluable tools in the realm of research and knowledge acquisition. They offer a wealth of advantages, including accessibility, time efficiency, expert interpretation, and the ability to provide valuable context. However, it is essential to acknowledge their inherent limitations, such as potential bias, loss of original context, and the risk of incomplete or outdated information. To harness the full potential of secondary sources, researchers must exercise critical judgment, corroborate information when possible, and recognize the complementarity of primary data. When used judiciously, secondary sources serve as indispensable intermediaries, enriching our understanding of complex subjects and contributing to the robust exchange of knowledge across various disciplines.

Understanding Primary, Secondary, and Tertiary Sources

In the previous chapter, we discussed various sources of information—from personal interviews to audio-visual recordings, Web pages to print materials, and more. Sources can be labeled primary , secondary , or tertiary , depending on their distance from the information they share.

Primary Sources

Primary sources give firsthand information—original and unfiltered. Examples are eyewitness accounts, personal journals, interviews, surveys, experiments, historical documents, and artifacts. These sources have a close, direct connection to their subjects.

Advantages: Primary sources directly address your topic and often provide information that is unavailable elsewhere. For example, the questions you compose for an interview or a survey will likely target your unique interest in the topic. Similarly, to test a particular hypothesis, you can design your own experiment.

Disadvantages: Some primary sources, such as eyewitness accounts, may be too close to the subject, lacking a critical distance. Others, such as interviews, surveys, and experiments, are time consuming to prepare, administer, and analyze. Finally, unless you have been trained in accepted methodologies, your own primary research in certain fields of study may not be recognized as valid.

Consider This

Whether a source is primary, secondary, or tertiary varies by topic. The letters from a Civil War soldier would be a primary source of information about his experiences. However, topics he might include about matters outside of his direct observation (other battle stories, news reported in the camp, etc.) would be considered either secondary or even tertiary information, depending on the situation.

Your Turn Imagine you are researching how the human brain is both like and unlike a computer. Where would you go for information? List two possible primary sources. Compare your ideas with a classmate’s.

Secondary Sources

Secondary sources are one step removed from the topic. While they can be just as valuable as primary sources, you must remember that secondary information is filtered through someone else’s perspective and may be biased.

Advantages: Secondary sources provide a variety of expert perspectives and insights. Also, peer review usually ensures the quality of sources such as scholarly articles. Finally, researching secondary sources is more efficient than planning, conducting, and analyzing certain primary forms of research.

Disadvantages: Because secondary sources are not necessarily focused on your specific topic, you may have to dig to find applicable information. Information may be colored by the researcher’s own bias or faulty approach. Also, secondary sources can become outdated (in some fields more quickly than in others).

Tertiary Sources

Tertiary sources provide thirdhand information by reporting ideas and details from secondary sources. This does not mean that tertiary sources have no value, merely that they include the potential for an additional layer of bias.

Advantages: They offer a quick, easy introduction to your topic. They may point to high-quality primary and secondary sources.

Disadvantages: Because of their distance, they may oversimplify or otherwise distort a topic. By rehashing secondary sources, they may miss new insights into a topic.

Primary vs. Secondary Sources: The Differences Explained

• peachyessay
• August 21, 2021
• Blogs , General

There are many reasons why students should learn to cite their sources when writing any academic paper. First and foremost, it indicates that the writer has done in-depth research when gathering relevant information pertaining to a particular topic. Secondly, it shows that the writer is a responsible scholar since they have given credit to the author and acknowledged their ideas. It also permits the reader to track down all the sources of information that were used to write the research paper .

By citing your sources correctly, you avoid getting caught up with incidents of plagiarism . By definition, plagiarism occurs when an individual borrows another person`s ideas and fails to acknowledge that they have done so. This is also referred to as the theft of intellectual property since the information was used without permission. It is important to note that plagiarism is a serious offense and it may have devastating consequences. In some instances, the student might be expelled from the learning institution while in other cases, they may be penalized and receive a failing grade. The most effective way to avoid plagiarism is by citing all the sources that have been used within the body of your academic paper.

When writing an essay, a research paper, or a custom term paper, unfortunately, the majority of the students do not know how to differentiate between primary and secondary sources. In most cases, this creates a lot of problems when it comes to writing research papers that require them to use different sources. One of the most effective ways of meeting the requirements of writing an academic paper is through taking time to understand the kind of sources that are needed and understanding the difference between the primary and secondary sources.

Primary Sources

A primary source means that it is the original book or article that was created by the author or a group of people. You might be wondering about the different types of primary sources that are available. Most people do not know that even published books such as a novel can be used as a primary source. A painting created by an artist can also be used as a primary source. However, in case it was a photocopy of a painting, it would be considered a secondary source. Other forms of primary sources include speeches, newspaper events, journal articles, court cases, photographs, poems, plays, short films and stories, and letters. For example, one of the speeches by President Obama could be used as a primary source. It is essential to note that primary sources usually consist of first-hand information in regard to something such as interviews, court recordings, diaries, or research studies conducted on different experiments.

Secondary Sources

These are sources that are written using information obtained from other primary sources. These sources often aid in analyzing, interpreting, and discussing information about the primary source. For instance, if a magazine writer wrote about a speech that was given by the President of the United States on September 20 th , it would be a secondary source. This is because the information is not original and it is aimed at analyzing the speech. In other words, it is true to state that a secondary source often talks about what is contained in the primary source. Although the information is not original, it analyses the speech that was given.

Secondary sources include specific essays, newspaper articles, reviews, dictionaries, encyclopedias, books, and journal articles. Apparently, it is true to state that the majority of the research papers are usually based on secondary sources since they build on studies or research that have been done by other people. Other types of secondary sources include television shows, videotapes, magazines, CD Rom, books, and other forms of reference materials. The majority of the secondary sources are usually used for completing research papers, or arguing someone else`s main points or thesis in regards to a particular topic. It is essential to note that there are situations where a source can be a secondary source in one journal article and a primary source in a different journal article. It all depends on the kind of relationship existing between the journal article and the writer.

Advantages and Disadvantages of Primary Sources

Primary sources are based on information gathered directly from the first-hand experience. It is information that is gathered for a specific research project. Most common examples of primary data sources include: Interviews, which could be a personal interview, telephone, e-mail; Self-administered surveys and questionnaires; Field observation; Experiments; Life histories; Action research; Case studies; Diary entries, letters, and other correspondence; Eyewitness accounts; Ethnographic research; and Personal narratives.

The most common secondary sources, on the other hand, include; Previous research; Mass media products; Government reports; Official statistics; Letters; Diaries; Web information; Historical data; Encyclopaedias; Monographs; Journal articles; Biography; Research analysis; Dissertations; Works of criticism and interpretation.

Advantages of primary source

Resolves a specific research issue

Undertaking your research permits you to address and resolve issues specific to your own situation. For instance, you might be interested in collecting information pertaining to a specific topic.

There is better accuracy

It is essential to note that primary sources are usually more accurate since they are directly collected for a specific topic or population.

Up-to-date information

Primary research is a great source of the latest information on a specific topic since all the relevant facts have been collected in real time. Unfortunately, in most cases, secondary sources do not contain up-to-date information and hence, they are not so much reliable.

You are the owner of the information

One of the benefits of primary sources is that the information collected by the researcher is shared to other people at will. Therefore, all the gathered information can remain hidden from other competitors.

Disadvantages of primary sources

They are more expensive

In most cases, it is very expensive to gather primary data since the research team has to collect information from scratch, which means they have to adhere to the entire research procedure that may involve research materials, processes, etc.

They are time-consuming

There is no doubt, the entire process of conducting primary research is time-consuming. It is essential to note that the amount of time taken is much more as compared to conducting the secondary research.

They have a lot of limitations

One of the drawbacks of primary sources is that they are limited to a specified place, time, and a number of participants among many other factors. A secondary source should contain information from many different sources for it to offer a lot of information.

Advantages of a secondary source

Secondary sources are easy to access

With the advancement of technology and the introduction of the internet in almost every place, it is currently easy to access information on anything just by the click of a mouse.

It is essential to note that most secondary sources are free to access. However, for those that need to be purchased, the costs are low.

Time-saving

A researcher or a student can perform endless research within a short duration. Just with a few Google searches, a person can find what they are searching for.

Generating new understanding and insights

It becomes easier to reanalyze old information and generate new levels of understanding on specific topics.

Any person can collect the data

The good thing about the secondary sources is that they can be used by people who are not familiar with the different types of qualitative and quantitative research methods . Any person can collect secondary information.

Disadvantages of secondary sources

Might not be specific to your needs

The information contained in the secondary source might not be specific to your needs because of the fact that it was collected at a different time or place, or maybe it was intended for a different purpose.

Lack of control over the quality of data

The researcher does not have any control over the quality of information. Since the data is significantly controlled by the data-driven market, there is a high possibility that the information might not be of the required quality.

Since the data contained in the secondary source is collected by a person just like you, the researcher might present the findings to suit his or her interests. In other cases, the researcher might fail to take note of facts and instead write about their opinions and perceptions.

Most of the information contained in secondary sources is collected from the past. This means that there is a high possibility that it might be outdated. This means that in some cases, the information presented might not be as effective as it is intended.

Distinguish Between a Primary Source and Secondary Source

There is no doubt that the data collection process plays an essential when it comes to statistical analysis of data. There are different methods for collecting primary and secondary data. To begin with, primary data entails information that is collected for the first time by the researcher, whereas secondary data involves information that has already been collected or published by other people. One of the main differences between primary and secondary data is that primary data is original and factual while secondary data involves the analysis and interpretation of primary data. The second major difference is that whereas the primary data is collected with the primary objective of finding a solution to a particular problem, secondary data, on the other hand, is collected for other different purposes. Primary data is real-time data whereas secondary data relates to the past. Primary data is collected for addressing the problem at hand while secondary data is collected for purposes other than the problem at hand. Although primary data collection is a very involved process, on the other hand, secondary data does not involve a lot of processes.

When to use primary sources

An individual can use primary sources when he or she has all the needed resources such as finance and time. This is because it usually involves a lot of resources since the researcher has to do everything from scratch. The use of primary sources could also be used in situations where information on a particular topic or subject has not been documented or contain scanty information. Finally, primary sources can be used in areas where the researcher would wish to avoid using biased information in their research work.

When to use secondary sources

Secondary sources can be used in situations where the researcher does not have adequate resources to undertake the research from scratch. The entire process of using primary sources is so expensive since it demands a lot of time and financial resources. By using secondary sources, a lot of time and resources will be saved. Secondary sources could also be used in situations where the writer would wish to compare the findings of different researchers. As a result, the researcher would be able to understand the different areas that were covered in a particular topic, and the gaps that exist. In essence, secondary sources are helpful when you are suffering from time constrain.

In conclusion, when undertaking your research, it is essential to take your time and put into consideration all the available data options. This will assist you to ensure that the right kind of data is used to arrive at a feasible solution or conclusion. It is essential to note that both secondary and primary data sources have applications in research and businesses. However, they may differ from one another in terms of the way they are collected, utilized, and thereafter analyzed. One of the major disadvantages of primary sources is that they are very expensive as compared to secondary sources in terms of the way information is collected. Most secondary sources, on the other hand, have issues of authenticity. Therefore, as you write your academic papers, you should take some time to think about whether it would be best to use primary or secondary sources. Ensure that whichever decision you settle on; the advantages outweigh the disadvantages.

Finding Sources

Primary and secondary sources.

Knowing the difference between primary and secondary sources will help you determine what types of sources you may need to include in your research essay. In general, primary sources are original works (original historical documents, art works, interviews, etc.), while secondary sources contain others’ insights and writings about those primary works (scholar articles about historical documents, art works, interviews, etc.).

While many scholarly sources are secondary sources, you will sometimes be asked to find primary sources in your research. For this reason, you should understand the differences between primary, secondary, and tertiary sources.

• Primary sources allow researchers to get as close as possible to original ideas, events, and empirical research as possible. Such sources may include creative works, first hand or contemporary accounts of events, and the publication of the results of empirical observations or research. These include diaries, interviews, speeches, photographs, etc.
• Secondary sources analyze, review, or summarize information in primary resources or other secondary resources. Even sources presenting facts or descriptions about events are secondary unless they are based on direct participation or observation. These include biographies, journal articles, books, and dissertations.
• Tertiary sources provide overviews of topics by synthesizing information gathered from other resources. Tertiary resources often provide data in a convenient form or provide information with context by which to interpret it. These are often grouped together with secondary sources. They include encyclopedias and dictionaries.

Analyze your topic/working thesis to determine the types of sources that can help with support.  For example, if your topic deals with Van Gogh’s use of pale green and what it connotes in his later paintings, you will need to couple evidence from primary sources (images of the paintings themselves) with secondary sources (other scholars’ views, discussions, and logical arguments about the same topic).  If your working thesis deals with the benefits of regular exercise for older adults in their 70s-90s, you may couple evidence from primary sources (uninterpreted data from research studies, interviews with older adults or experts in the field) with secondary sources (interpretations of research studies).  In some cases, you may find that your research is mostly from secondary sources and that’s fine, depending on your topic and working thesis.  Just make sure to consider, consciously, the types of sources that can best be used to support your own ideas.

The following video provides a clear overview of primary and secondary sources.

Literature Sources: Primary, Secondary, and Online Essay

The pros and cons of different literature sources, online resources: webnotes, zotero, refworks, reference list.

There are loads of primary and secondary sources which can be used in different types of research. Admittedly, scholarly journals, theses, monographs and certain newspapers are regarded as reliable sources as it is easy to trace the author’s ‘academic background’ or professionalism, so-to-speak. When it comes to electronic sources, the degree of credibility is rather low as it is often difficult to trace the author of the paper. Admittedly, it is impossible to base your research on data which cannot be checked. However, electronic sources can also be reliable as long as the source is taken from an online library or database. Luckily, numerous online databases provide a variety of reliable sources.

When doing research, the researcher should remember that primary sources are essential as they contain specific data with no (or minimal) bias. Secondary sources, on the contrary, include other researchers’ opinions, which can also be valuable as any academic research is a part of the larger discourse. Thus, the researcher uses data from primary sources to analyze, and secondary sources are used to support ideas and join the on-going academic discourse.

For instance, when working on class tardiness, it is possible to use a variety of sources. One of possible primary sources to use is a report made by Robers, Zhang, Truman and Snyder (2012) as this report contains specific data on number of students who are late. Another primary source is an article by Spoone (2010) who provides particular reasons for students’ being late. As for the secondary sources, one of such sources is a newspaper article by Wesler (2010) who focuses on one of the schools where a specific program to diminish class tardiness is launched. This source is full of opinions and evaluations, so it can’t be regarded as primary. One more secondary source to be used is the article by Formica (2008) who expresses his opinion on the matter. This opinion is valuable for the research which also highlights opinions on the topic.

Notably, technology is helping students immensely as now it is easy to collect, analyze, cite, store and even share a variety of sources with the help of software. WebNotes and Zotero are online resources that can help do any research. Some of the most helpful services offered is that these tools help implement research. These tools can be regarded as a huge library in one’s computer. The tools enable the researcher to access a variety of libraries and databases. More so, it is easy to make notes and store the necessary information. However, there is a pitfall as the use of these resources may lead to abundance of information. It is so tempting to make a note in numerous articles. However, many of these sources turn out to be redundant.

One more helpful online resource is RefWorks. One of its most helpful features is the availability of tutorials. Sometimes I can find it difficult to use some software, but I had no problems with RefWorks. Another feature is that it is online based. Thus, I can access my database anywhere and 24/7. Finally, the resource is user-friendly and it helps implement research effectively. I can access a variety of online databases and I can easily manage my sources. These features help me save a lot of time and focus on the research itself, rather than on managing my sources and struggling to find the quote I need.
