How to Find Sources | Scholarly Articles, Books, Etc.

Published on June 13, 2022 by Eoghan Ryan . Revised on May 31, 2023.

It’s important to know how to find relevant sources when writing a  research paper , literature review , or systematic review .

The types of sources you need will depend on the stage you are at in the research process , but all sources that you use should be credible , up to date, and relevant to your research topic.

There are three main places to look for sources to use in your research:

Research databases

• Your institution’s library
• Other online resources

Table of contents

Library resources, other online sources, other interesting articles, frequently asked questions about finding sources.

You can search for scholarly sources online using databases and search engines like Google Scholar . These provide a range of search functions that can help you to find the most relevant sources.

If you are searching for a specific article or book, include the title or the author’s name. Alternatively, if you’re just looking for sources related to your research problem , you can search using keywords. In this case, it’s important to have a clear understanding of the scope of your project and of the most relevant keywords.

Databases can be general (interdisciplinary) or subject-specific.

• You can use subject-specific databases to ensure that the results are relevant to your field.
• When using a general database or search engine, you can still filter results by selecting specific subjects or disciplines.

Example: JSTOR discipline search filter

Check the table below to find a database that’s relevant to your research.

Google Scholar

To get started, you might also try Google Scholar , an academic search engine that can help you find relevant books and articles. Its “Cited by” function lets you see the number of times a source has been cited. This can tell you something about a source’s credibility and importance to the field.

Example: Google Scholar “Cited by” function

Boolean operators

Boolean operators can also help to narrow or expand your search.

Boolean operators are words and symbols like AND , OR , and NOT that you can use to include or exclude keywords to refine your results. For example, a search for “Nietzsche NOT nihilism” will provide results that include the word “Nietzsche” but exclude results that contain the word “nihilism.”

Many databases and search engines have an advanced search function that allows you to refine results in a similar way without typing the Boolean operators manually.

Example: Project Muse advanced search

You can find helpful print sources in your institution’s library. These include:

• Journal articles
• Encyclopedias
• Newspapers and magazines

Make sure that the sources you consult are appropriate to your research.

You can find these sources using your institution’s library database. This will allow you to explore the library’s catalog and to search relevant keywords. You can refine your results using Boolean operators .

Once you have found a relevant print source in the library:

• Consider what books are beside it. This can be a great way to find related sources, especially when you’ve found a secondary or tertiary source instead of a primary source .
• Consult the index and bibliography to find the bibliographic information of other relevant sources.

You can consult popular online sources to learn more about your topic. These include:

• Crowdsourced encyclopedias like Wikipedia

You can find these sources using search engines. To refine your search, use Boolean operators in combination with relevant keywords.

However, exercise caution when using online sources. Consider what kinds of sources are appropriate for your research and make sure the sites are credible .

Look for sites with trusted domain extensions:

• URLs that end with .edu are educational resources.
• URLs that end with .gov are government-related resources.
• DOIs often indicate that an article is published in a peer-reviewed , scientific article.

Other sites can still be used, but you should evaluate them carefully and consider alternatives.

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

You can find sources online using databases and search engines like Google Scholar . Use Boolean operators or advanced search functions to narrow or expand your search.

For print sources, you can use your institution’s library database. This will allow you to explore the library’s catalog and to search relevant keywords.

It is important to find credible sources and use those that you can be sure are sufficiently scholarly .

• Consult your institute’s library to find out what books, journals, research databases, and other types of sources they provide access to.
• Look for books published by respected academic publishing houses and university presses, as these are typically considered trustworthy sources.
• Look for journals that use a peer review process. This means that experts in the field assess the quality and credibility of an article before it is published.

When searching for sources in databases, think of specific keywords that are relevant to your topic , and consider variations on them or synonyms that might be relevant.

Once you have a clear idea of your research parameters and key terms, choose a database that is relevant to your research (e.g., Medline, JSTOR, Project MUSE).

Find out if the database has a “subject search” option. This can help to refine your search. Use Boolean operators to combine your keywords, exclude specific search terms, and search exact phrases to find the most relevant sources.

There are many types of sources commonly used in research. These include:

You’ll likely use a variety of these sources throughout the research process , and the kinds of sources you use will depend on your research topic and goals.

Scholarly sources are written by experts in their field and are typically subjected to peer review . They are intended for a scholarly audience, include a full bibliography, and use scholarly or technical language. For these reasons, they are typically considered credible sources .

Popular sources like magazines and news articles are typically written by journalists. These types of sources usually don’t include a bibliography and are written for a popular, rather than academic, audience. They are not always reliable and may be written from a biased or uninformed perspective, but they can still be cited in some contexts.

How to start a search for sources, 1. start simple.

If you’re wondering how to find sources for a research paper, the easiest and best way to start is simple! Just try browsing through some common search engines to see what you find.

2. Cross Wikipedia off

Wikipedia, although it’s a massive pool of information, should always be avoided when writing a research paper since it allows the public to edit information. Sites such as these often run the risk of lacking accuracy, and is not one of the most credible sources for research.

3. Yes to scholarly databases

Scholarly databases are your best friend when it comes to finding credible sources for research. Online scholarly databases that can be trusted and are known to provide useful information for students include LexisNexis and EBSCO.

4. Newspapers and magazines

Although sometimes biased, newspapers and magazines can also be a great place to find information about current events.

5. The library

While the library seems to be the most obvious place to find information, somehow it’s often forgotten when it comes to research in the modern age. Don’t forget how useful it can truly be!

Types of Credible Sources for Research

1. what are some credible websites.

Many online sources do not necessarily contain information that is correct or has been checked. That’s why it’s of utmost importance to make sure that you’re using the right websites for your research, with government and educational websites generally being the most reliable.

Credible sources for research include: science.gov, The World Factbook, US Census Bureau, UK Statistics, and Encyclopedia Britannica.

2. What are some credible journal articles?

When it comes to journal articles, determining how credible they are comes much easier than other sources. This is generally due to the fact that many of these websites will include valuable information such as how many times the article has been cited, and if its been peer reviewed.

Some great examples of reliable websites for journal articles include Google Scholar, Oxford Academic, Microsoft Academic, Cornell University Library, and SAGE Publishing.

If you are ever not sure how to find credible sources, then there’s the CRAAP test, which takes into account the Currency, Relevance, Authority, Accuracy and Purpose of the article. Take all of these factors into consideration before using a source and determining whether or not it’s credible enough. Even if it takes more time, you’ll be saving yourself tons of time in the long run by not using unreliable sources.

3. what are some credible news sources.

When it comes to news articles, more caution must be taken since it’s hard to know which sources are truly reliable and unbiased. The CRAAP test is also useful in this type of article for research.

A few examples of credible news sources include The New York Times, Bloomberg, and The Washington Post.

The Credibility of a Source

As you search for your research information, you will surely come across the question of how to find credible sources for a research paper. Here are some criteria to focus on to ensure that you only use the most credible of sources.

1. What’s the depth of it?

Always look at the depth of an article, not just the written content. See how long the article is, and if it contains the necessary information such as an abstract, a reference list, and documented data.

2. Who is reading it?

When judging the credibility of an article, it’s important to always ask yourself who the target audience of the article is. Sometimes, sources have a specific goal in mind and it can create certain biases.

3. What’s the goal?

Just as you should do with the audience, also ask yourself what the article is trying to achieve. What is their ultimate goal and how are they persuading you of that?

4. Who wrote it?

Always ask yourself who wrote the article and how reputable they are in the specific field. Look at what other published works they have as well.

5. Can it be trusted?

Overall, it’s key to ask yourself how reputable the source is. What kind of website is it published on? Look at the big picture.

6. Is it relevant to now?

Look at the date of the article, or about the specific things they are mentioning in the article. If it’s from a few years ago, it’s probably not too relevant to your current research.

7. Can it be proven?

While an article may sound incredibly convincing, many people have a way with words and persuasion. Stop and ask yourself whether or not what they are claiming can actually be proven.

How to evaluate source credibility.

By using unreliable sources in your research, it can discredit your status, which is why it’s incredibly important to make sure that any information you are using is up-to-date and accurate.

Here’s how to find credible sources.

1. What is a credible source?

Generally, materials that have been published within the past 10 years are considered to be credible sources for research. Another important factor to consider is the author — if they are well known and respected in their specific fields, that’s also generally a sign that the article is credible. Educational and government-run websites (.gov, .edu) tend to also be a safe source to use, as well as academic databases. Google Scholar is also a no-fail source for reliable information.

2. What is a potentially unreliable source?

Anything that is out of date, meaning it’s been published more than 10 years ago should be avoided. Materials published on social media platforms such as Facebook or personal blogs don’t tend to be the most credible. Always make sure that an article contains proper citations and that the website you are using ends in .com or .org.

Free Resources For Learning

There are many free resources for research available known as open educational resources . They are licensed for free use, with the intention of teaching. They can be determined as credible sources for research if they have a Creative Common license, and if the author has proven to be an expert in their field. Always make sure that the content you are using contains no biases.

Sites For Scholarly Research

When performing scholarly research, it’s extra important to make sure that your sources are credible. Government-run research is considered credible, but beware of any political sites. University and educational websites also tend to be reliable, but still take everything you read with a grain of salt. Company websites also tend to be reliable, although their ultimate goal is usually to promote a product. Organizations which are .org websites can be professional and reliable, however, sometimes they also have their own interests.

Which Sites Can Be Relied On

The internet has no shortage of information out there. That’s why you’ll need these handy tips to determine which to use, and how to distinguish through the vast choices without feeling overwhelmed.

List of Credible Research Sources to Consider

1. government entities.

These websites tend to be reliable since they are highly regulated. Examples include the CIA World Factbook and the United States Justice Statistics.

2. Research Think Tanks

Examples of reliable research think tanks include Rand Corporation, Pew Research Center and The Milken Institute.

3. Academic Libraries and Databases

ProQuest, Scopus, and Jstor are great examples of academic libraries and databases that can be trusted.

4. Professional Standards Organizations

The American Bar Association and The American Psychological Association (APA) are highly credible sources when it comes to professional standards.

How to Write a Research Paper: Step-by-Step

Now that you’re an expert on finding credible sources for research, you’re ready to go! But how do you even start to write a research paper? Don’t worry, we’ve got you covered.

For starters, it’s important to get clear instructions from your professor on what they want. The next step is to start brainstorming ideas for a topic of research. Once you’ve decided and feel confident about it, you’re ready to create your outline and plan out the goal of your research paper.

21 Legit Research Databases for Free Journal Articles in 2024

#scribendiinc

Written by  Scribendi

Has this ever happened to you? While looking for websites for research, you come across a research paper site that claims to connect academics to a peer-reviewed article database for free.

Intrigued, you search for keywords related to your topic, only to discover that you must pay a hefty subscription fee to access the service. After the umpteenth time being duped, you begin to wonder if there's even such a thing as free journal articles.

Subscription fees and paywalls are often the bane of students and academics, especially those at small institutions who don't provide access to many free article directories and repositories.

Whether you're working on an undergraduate paper, a PhD dissertation, or a medical research study, we want to help you find tools to locate and access the information you need to produce well-researched, compelling, and innovative work.

Below, we discuss why peer-reviewed articles are superior and list out the best free article databases to use in 2024.

Why peer-reviewed scholarly journal articles are more authoritative.

Determining what sources are reliable can be challenging. Peer-reviewed scholarly journal articles are the gold standard in academic research. Reputable academic journals have a rigorous peer-review process.

The peer review process provides accountability to the academic community, as well as to the content of the article. The peer review process involves qualified experts in a specific (often very specific) field performing a review of an article's methods and findings to determine things like quality and credibility.

Peer-reviewed articles can be found in peer-reviewed article databases and research databases, and if you know that a database of journals is reliable, that can offer reassurances about the reliability of a free article. Peer review is often double blind, meaning that the author removes all identifying information and, likewise, does not know the identity of the reviewers. This helps reviewers maintain objectivity and impartiality so as to judge an article based on its merit.

Where to Find Peer-Reviewed Articles

Peer-reviewed articles can be found in a variety of research databases. Below is a list of some of the major databases you can use to find peer-reviewed articles and other sources in disciplines spanning the humanities, sciences, and social sciences.

What Are Open Access Journals?

An open access (OA) journal is a journal whose content can be accessed without payment. This provides scholars, students, and researchers with free journal articles. OA journals use alternate methods of funding to cover publication costs so that articles can be published without having to pass those publication costs on to the reader.

Some of these funding models include standard funding methods like advertising, public funding, and author payment models, where the author pays a fee in order to publish in the journal. There are OA journals that have non-peer-reviewed academic content, as well as journals that focus on dissertations, theses, and papers from conferences, but the main focus of OA is peer-reviewed scholarly journal articles.

The internet has certainly made it easier to access research articles and other scholarly publications without needing access to a university library, and OA takes another step in that direction by removing financial barriers to academic content.

Choosing Wisely

Features of legitimate oa journals.

 There are things to look out for when trying to decide if a free publication journal is legitimate:

Mission statement —The mission statement for an OA journal should be available on their website.

Publication history —Is the journal well established? How long has it been available?

Editorial board —Who are the members of the editorial board, and what are their credentials?

Indexing —Can the journal be found in a reliable database?

Peer review —What is the peer review process? Does the journal allow enough time in the process for a reliable assessment of quality?

Impact factor —What is the average number of times the journal is cited over a two-year period?

Features of Illegitimate OA Journals

There are predatory publications that take advantage of the OA format, and they are something to be wary of. Here are some things to look out for:

Contact information —Is contact information provided? Can it be verified?

Turnaround —If the journal makes dubious claims about the amount of time from submission to publication, it is likely unreliable.

Editorial board —Much like determining legitimacy, looking at the editorial board and their credentials can help determine illegitimacy.

Indexing —Can the journal be found in any scholarly databases?

Peer review —Is there a statement about the peer review process? Does it fit what you know about peer review?

How to Find Scholarly Articles

Identify keywords.

Keywords are included in an article by the author. Keywords are an excellent way to find content relevant to your research topic or area of interest. In academic searches, much like you would on a search engine, you can use keywords to navigate through what is available to find exactly what you're looking for.

Authors provide keywords that will help you easily find their article when researching a related topic, often including general terms to accommodate broader searches, as well as some more specific terms for those with a narrower scope. Keywords can be used individually or in combination to refine your scholarly article search.

Narrow Down Results

Sometimes, search results can be overwhelming, and searching for free articles on a journal database is no exception, but there are multiple ways to narrow down your results. A good place to start is discipline.

What category does your topic fall into (psychology, architecture, machine learning, etc.)? You can also narrow down your search with a year range if you're looking for articles that are more recent.

A Boolean search can be incredibly helpful. This entails including terms like AND between two keywords in your search if you need both keywords to be in your results (or, if you are looking to exclude certain keywords, to exclude these words from the results).

Consider Different Avenues

If you're not having luck using keywords in your search for free articles, you may still be able to find what you're looking for by changing your tactics. Casting a wider net sometimes yields positive results, so it may be helpful to try searching by subject if keywords aren't getting you anywhere.

You can search for a specific publisher to see if they have OA publications in the academic journal database. And, if you know more precisely what you're looking for, you can search for the title of the article or the author's name.

Determining the Credibility of Scholarly Sources

Ensuring that sources are both credible and reliable is crucial to academic research. Use these strategies to help evaluate the usefulness of scholarly sources:

• Peer Review : Look for articles that have undergone a rigorous peer-review process. Peer-reviewed articles are typically vetted by experts in the field, ensuring the accuracy of the research findings.

Tip: To determine whether an article has undergone rigorous peer review, review the journal's editorial policies, which are often available on the journal's website. Look for information about the peer-review process, including the criteria for selecting reviewers, the process for handling conflicts of interest, and any transparency measures in place.

• Publisher Reputation : Consider the reputation of the publisher. Established publishers, such as well-known academic journals, are more likely to adhere to high editorial standards and publishing ethics.
• Author Credentials : Evaluate the credentials and expertise of the authors. Check their affiliations, academic credentials, and past publications to assess their authority in the field.
• Citations and References : Examine the citations and references provided in the article. A well-researched article will cite credible sources to support its arguments and findings. Verify the accuracy of the cited sources and ensure they are from reputable sources.
• Publication Date : Consider the publication date of the article. While older articles may still be relevant, particularly in certain fields, it is best to prioritize recent publications for up-to-date research and findings.
• Journal Impact Factor : Assess the journal's impact factor or other metrics that indicate its influence and reputation within the academic community. Higher impact factor journals are generally considered more prestigious and reliable. 

Tip: Journal Citation Reports (JCR), produced by Clarivate Analytics, is a widely used source for impact factor data. You can access JCR through academic libraries or directly from the Clarivate Analytics website if you have a subscription.

• Peer Recommendations : Seek recommendations from peers, mentors, or professors in your field. They can provide valuable insights and guidance on reputable sources and journals within your area of study.
• Cross-Verification : Cross-verify the information presented in the article with other credible sources. Compare findings, methodologies, and conclusions with similar studies to ensure consistency and reliability.

By employing these strategies, researchers can confidently evaluate the credibility and reliability of scholarly sources, ensuring the integrity of their research contributions in an ever-evolving landscape.

How to find peer-reviewed articles.

There are a lot of free scholarly articles available from various sources. The internet is a big place. So how do you go about finding peer-reviewed articles when conducting your research? It's important to make sure you are using reputable sources.

The first source of the article is the person or people who wrote it. Checking out the author can give you some initial insight into how much you can trust what you’re reading. Looking into the publication information of your sources can also indicate whether the article is reliable.

Aspects of the article, such as subject and audience, tone, and format, are other things you can look at when evaluating whether the article you're using is valid, reputable, peer-reviewed material. So, let's break that down into various components so you can assess your research to ensure that you're using quality articles and conducting solid research.

Check the Author

Peer-reviewed articles are written by experts or scholars with experience in the field or discipline they're writing about. The research in a peer-reviewed article has to pass a rigorous evaluation process, so it's a foregone conclusion that the author(s) of a peer-reviewed article should have experience or training related to that research.

When evaluating an article, take a look at the author's information. What credentials does the author have to indicate that their research has scholarly weight behind it? Finding out what type of degree the author has—and what that degree is in—can provide insight into what kind of authority the author is on the subject.

Something else that might lend credence to the author's scholarly role is their professional affiliation. A look at what organization or institution they are affiliated with can tell you a lot about their experience or expertise. Where were they trained, and who is verifying their research?

Identify Subject and Audience

The ultimate goal of a study is to answer a question. Scholarly articles are also written for scholarly audiences, especially articles that have gone through the peer review process. This means that the author is trying to reach experts, researchers, academics, and students in the field or topic the research is based on.

Think about the question the author is trying to answer by conducting this research, why, and for whom. What is the subject of the article? What question has it set out to answer? What is the purpose of finding the information? Is the purpose of the article of importance to other scholars? Is it original content?

Research should also be approached analytically. Is the methodology sound? Is the author using an analytical approach to evaluate the data that they have obtained? Are the conclusions they've reached substantiated by their data and analysis? Answering these questions can reveal a lot about the article's validity.

Format Matters

Reliable articles from peer-reviewed sources have certain format elements to be aware of. The first is an abstract. An abstract is a short summary or overview of the article. Does the article have an abstract? It's unlikely that you're reading a peer-reviewed article if it doesn't. Peer-reviewed journals will also have a word count range. If an article seems far too short or incredibly long, that may be reason to doubt it.

Another feature of reliable articles is the sections the information is divided into. Peer-reviewed research articles will have clear, concise sections that appropriately organize the information. This might include a literature review, methodology, and results in the case of research articles and a conclusion.

One of the most important sections is the references or bibliography. This is where the researcher lists all the sources of their information. A peer-reviewed source will have a comprehensive reference section.

An article that has been written to reach an academic community will have an academic tone. The language that is used, and the way this language is used, is important to consider. If the article is riddled with grammatical errors, confusing syntax, and casual language, it almost definitely didn't make it through the peer review process.

Also consider the use of terminology. Every discipline is going to have standard terminology or jargon that can be used and understood by other academics in the discipline. The language in a peer-reviewed article is going to reflect that.

If the author is going out of their way to explain simple terms, or terms that are standard to the field or discipline, it's unlikely that the article has been peer reviewed, as this is something that the author would be asked to address during the review process.

Publication

The source of the article will be a very good indicator of the likelihood that it was peer reviewed. Where was the article published? Was it published alongside other academic articles in the same discipline? Is it a legitimate and reputable scholarly publication?

A trade publication or newspaper might be legitimate or reputable, but it is not a scholarly source, and it will not have been subject to the peer review process. Scholarly journals are the best resource for peer-reviewed articles, but it's important to remember that not all scholarly journals are peer reviewed.

It's helpful to look at a scholarly source's website, as peer-reviewed journals will have a clear indication of the peer review process. University libraries, institutional repositories, and reliable databases (and you now might have a list of some legit ones) can also help provide insight into whether an article comes from a peer-reviewed journal.

Common Research Mistakes to Avoid

Research is a lot of work. Even with high standards and good intentions, it's easy to make mistakes. Perhaps you searched for access to scientific journals for free and found the perfect peer-reviewed sources, but you forgot to document everything, and your references are a mess. Or, you only searched for free online articles and missed out on a ground-breaking study that was behind a paywall.

Whether your research is for a degree or to get published or to satisfy your own inquisitive nature, or all of the above, you want all that work to produce quality results. You want your research to be thorough and accurate.

To have any hope of contributing to the literature on your research topic, your results need to be high quality. You might not be able to avoid every potential mistake, but here are some that are both common and easy to avoid.

Sticking to One Source

One of the hallmarks of good research is a healthy reference section. Using a variety of sources gives you a better answer to your question. Even if all of the literature is in agreement, looking at various aspects of the topic may provide you with an entirely different picture than you would have if you looked at your research question from only one angle.

Not Documenting Every Fact

As you conduct your research, do yourself a favor and write everything down. Everything you include in your paper or article that you got from another source is going to need to be added to your references and cited.

It's important, especially if your aim is to conduct ethical, high-quality research, that all of your research has proper attribution. If you don't document as you go, you could end up making a lot of work for yourself if the information you don't write down is something that later, as you write your paper, you really need.

Using Outdated Materials

Academia is an ever-changing landscape. What was true in your academic discipline or area of research ten years ago may have since been disproven. If fifteen studies have come out since the article that you're using was published, it's more than a little likely that you're going to be basing your research on flawed or dated information.

If the information you're basing your research on isn't as up-to-date as possible, your research won't be of quality or able to stand up to any amount of scrutiny. You don't want all of your hard work to be for naught.

Relying Solely on Open Access Journals

OA is a great resource for conducting academic research. There are high-quality journal articles available through OA, and that can be very helpful for your research. But, just because you have access to free articles, that doesn't mean that there's nothing to be found behind a paywall.

Just as dismissing high-quality peer-reviewed articles because they are OA would be limiting, not exploring any paid content at all is equally short-sighted. If you're seeking to conduct thorough and comprehensive research, exploring all of your options for quality sources is going to be to your benefit.

Digging Too Deep or Not Deep Enough

Research is an art form, and it involves a delicate balance of information. If you conduct your research using only broad search terms, you won't be able to answer your research question well, or you'll find that your research provides information that is closely related to your topic but, ultimately, your findings are vague and unsubstantiated.

On the other hand, if you delve deeply into your research topic with specific searches and turn up too many sources, you might have a lot of information that is adjacent to your topic but without focus and perhaps not entirely relevant. It's important to answer your research question concisely but thoroughly.

Different Types of Scholarly Articles

Different types of scholarly articles have different purposes. An original research article, also called an empirical article, is the product of a study or an experiment. This type of article seeks to answer a question or fill a gap in the existing literature.

Research articles will have a methodology, results, and a discussion of the findings of the experiment or research and typically a conclusion.

Review articles overview the current literature and research and provide a summary of what the existing research indicates or has concluded. This type of study will have a section for the literature review, as well as a discussion of the findings of that review. Review articles will have a particularly extensive reference or bibliography section.

Theoretical articles draw on existing literature to create new theories or conclusions, or look at current theories from a different perspective, to contribute to the foundational knowledge of the field of study.

10 Tips for Navigating Journal Databases

Use the right academic journal database for your search, be that interdisciplinary or specific to your field. Or both!

If it's an option, set the search results to return only peer-reviewed sources.

Start by using search terms that are relevant to your topic without being overly specific.

Try synonyms, especially if your keywords aren't returning the desired results.

Even if you've found some good articles, try searching using different terms.

Explore the advanced search features of the database(s).

Learn to use Booleans (AND, OR, NOT) to expand or narrow your results.

Once you've gotten some good results from a more general search, try narrowing your search.

Read through abstracts when trying to find articles relevant to your research.

Keep track of your research and use citation tools. It'll make life easier when it comes time to compile your references.

7 Frequently Asked Questions

1. how do i get articles for free.

Free articles can be found through free online academic journals, OA databases, or other databases that include OA journals and articles. These resources allow you to access free papers online so you can conduct your research without getting stuck behind a paywall.

Academics don't receive payment for the articles they contribute to journals. There are often, in fact, publication fees that scholars pay in order to publish. This is one of the funding structures that allows OA journals to provide free content so that you don't have to pay fees or subscription costs to access journal articles.

2. How Do I Find Journal Articles?

Journal articles can be found in databases and institutional repositories that can be accessed at university libraries. However, online research databases that contain OA articles are the best resource for getting free access to journal articles that are available online.

Peer-reviewed journal articles are the best to use for academic research, and there are a number of databases where you can find peer-reviewed OA journal articles. Once you've found a useful article, you can look through the references for the articles the author used to conduct their research, and you can then search online databases for those articles, too.

3. How Do I Find Peer-Reviewed Articles?

Peer-reviewed articles can be found in reputable scholarly peer-reviewed journals. High-quality journals and journal articles can be found online using academic search engines and free research databases. These resources are excellent for finding OA articles, including peer-reviewed articles.

OA articles are articles that can be accessed for free. While some scholarly search engines and databases include articles that aren't peer reviewed, there are also some that provide only peer-reviewed articles, and databases that include non-peer-reviewed articles often have advanced search features that enable you to select "peer review only." The database will return results that are exclusively peer-reviewed content.

4. What Are Research Databases?

A research database is a list of journals, articles, datasets, and/or abstracts that allows you to easily search for scholarly and academic resources and conduct research online. There are databases that are interdisciplinary and cover a variety of topics.

For example, Paperity might be a great resource for a chemist as well as a linguist, and there are databases that are more specific to a certain field. So, while ERIC might be one of the best educational databases available for OA content, it's not going to be one of the best databases for finding research in the field of microbiology.

5. How Do I Find Scholarly Articles for Specific Fields?

There are interdisciplinary research databases that provide articles in a variety of fields, as well as research databases that provide articles that cater to specific disciplines. Additionally, a journal repository or index can be a helpful resource for finding articles in a specific field.

When searching an interdisciplinary database, there are frequently advanced search features that allow you to narrow the search results down so that they are specific to your field. Selecting "psychology" in the advanced search features will return psychology journal articles in your search results. You can also try databases that are specific to your field.

If you're searching for law journal articles, many law reviews are OA. If you don't know of any databases specific to history, visiting a journal repository or index and searching "history academic journals" can return a list of journals specific to history and provide you with a place to begin your research.

6. Are Peer-Reviewed Articles Really More Legitimate?

The short answer is yes, peer-reviewed articles are more legitimate resources for academic research. The peer review process provides legitimacy, as it is a rigorous review of the content of an article that is performed by scholars and academics who are experts in their field of study. The review provides an evaluation of the quality and credibility of the article.

Non-peer-reviewed articles are not subject to a review process and do not undergo the same level of scrutiny. This means that non-peer-reviewed articles are unlikely, or at least not as likely, to meet the same standards that peer-reviewed articles do.

7. Are Free Article Directories Legitimate?

❓ Why Is It Important to Use Credible Sources in Research?

It is crucial to use credible sources while working on your research: you need to back up your argument with trustworthy evidence. It can only be possible if the sources you use are reliable and their credibility is indisputable.

❓ Why Are Government Websites Reliable?

Government websites provide only official data and statistics in their works. They also publish results of well-known researchers, which are trusted all around the world.

❓ What Are Non-Credible Sources?

Non-credible sources are the ones that you can’t trust. These websites contain information that isn’t proven. There is no evidence or backup facts for the information mentioned there. It is dangerous to use non-credible sources while doing your research, as they might be misleading. As a result, your research might be considered biased or even wrong. g.

❓ What Are Some Examples of Unreliable Sources?

Unreliable sources often have a strange design. The links are broken, and you see grammar and spelling errors. These websites probably lack authors or sources of information. Non-credible sources are not associated with credible institutions or organizations.

Information about effects of treatments based on unsystematic reviews of research evidence may be misleading. However, finding trustworthy information about the effects of treatments based on systematic reviews, which is accessible to patients and the public can be difficult. The objectives of this study were to identify and evaluate free sources of health information for patients and the public that provide information about effects of treatments based on systematic reviews.

We reviewed websites that we and our colleagues knew of, searched for government sponsored health information websites, and searched for online sources of health information that provide evidence-based information. To be included in our review, a website had to be available in English, freely accessible, and intended for patients and the public. In addition, it had to have a broad scope, not limited to specific conditions or types of treatments. It had to include a description of how the information is prepared and the description had to include a statement about using systematic reviews. We compared the included websites by searching for information about the effects of eight treatments.

Three websites met our inclusion criteria: Cochrane Evidence , Informed Health , and PubMed Health . The first two websites produce content, whereas PubMed Health aggregated content. A fourth website that met our inclusion criteria, CureFacts , was under development. Cochrane Evidence provides plain language summaries of Cochrane Reviews (i.e. summaries that are intended for patients and the public). They are translated to several other languages. No information besides treatment effects is provided. Informed Health provides information about treatment effects together with other information for a wide range of topics. PubMed Health was discontinued in October 2018. It included a large number of systematic reviews of treatment effects with plain language summaries for Cochrane Reviews and some other reviews. None of the three websites included links to ongoing trials, and information about treatment effects was not reported consistently on any of the websites.

It is possible for patients and the public to access trustworthy information about the effects of treatments using the two of the websites included in this review.

Electronic supplementary material

The online version of this article (10.1186/s12911-019-0772-5) contains supplementary material, which is available to authorized users.

Patients and the public must make choices among different treatment options. We define “treatment” broadly, as any preventive, therapeutic, rehabilitative, or palliative action intended to improve the health or wellbeing of individuals or communities [ 1 ]. This includes, for example, drugs, surgery and other types of “modern medicine”; lifestyle changes, such as changes to what you eat or how you exercise; herbal remedies and other types of “traditional” or “alternative medicine”, and public health interventions. Few people would prefer that decisions about what they should and should not do for their health should be uninformed. Yet, if a decision is going to be well informed rather than misinformed, they need information that is relevant, trustworthy, and accessible. They also need to be able to distinguish between claims about the effects of treatments that are trustworthy and those that are not [ 2 ].

Often the problem is too much information rather than too little. For example, a Google search for “back pain” yields over 60 million hits [ 3 ]. PubMed, a free search engine for accessing MEDLINE and other databases maintained by the United States National Library of Medicine, includes over 27 million citations [ 4 ], and this represents only a fraction of the biomedical literature. The Cochrane Central Register of Controlled Trials, a bibliographic database that is restricted to controlled trials of treatments, contains over a million citations [ 5 ]. It is not practical for people making decisions about treatments to use search engines or databases such as these to find relevant information, critically appraise the studies they find, synthesize them, and interpret the results.

Systematic reviews reduce the risk of being misled by bias (systematic errors) and the play of chance (random errors), by using systematic and explicit methods to identify, select, and critically appraise relevant studies, and to collect and analyse data from them [ 6 ]. For information about treatment effects to be trustworthy, it should be based on systematic reviews. For it to be accessible to patients and the public, it should be easy to find and should be clearly communicated in plain language [ 7 ].

Unfortunately, a large amount of information about treatment effects is not based on systematic reviews and is not trustworthy [ 8 – 19 ]. This includes handouts for patients [ 8 , 9 ], internet-based information [ 10 , 11 ], information in social and mass media [ 12 – 18 ], information produced by patient organisations [ 8 , 9 , 12 ]. press releases [ 18 ], and advertisements [ 19 ]. Studies of the trustworthiness of health information have used a variety of criteria, but have consistently found important limitations [ 8 – 19 ]. Although trustworthy information about treatment effects can be found, evidence-based information is frequently written for health professionals or researchers, rather than for patients and the public [ 7 ].

There is an abundance of health information on the internet, which has become an important source of health information over the past two decades [ 10 , 11 , 20 – 24 ], but patients and the public find it difficult to search the internet for trustworthy information [ 21 – 23 ], and are unlikely to critically appraise the information that they do find [ 22 , 23 ].

There are a number of websites that aim to improve access to trustworthy health information for patients and the public. The objectives of this study were to identify free sources of health information for patients and the public which provide information about the effects of treatments based on systematic reviews, and to evaluate those websites.

Our motivation for undertaking this review grew out of a desire to respond to people who were looking for trustworthy information about the effects of specific treatments and landed on Testing Treatments international [ 25 ], a website for promoting critical thinking about treatment claims. Rather than simply noting that the Testing Treatments website does not provide the information they were seeking, we wanted to help them by directing them to sources that do provide this information. Given this motivation, we restricted our review of websites to ones with a broad scope. There were two reasons for this. First, websites with a broad scope can meet the needs of most people seeking trustworthy information about treatment effects. Furthermore, although disease-specific websites can be useful, it would be impractical to assess any more than a small sample of websites for specific conditions or types of treatments. Second, it is easier to become familiar with one or a small number of websites than it is to use multiple websites for questions about different conditions or types of treatments.

We considered any website that defined itself as providing “health information”, which included information about treatments. To be included in this review a website needed to be:

• Available in English
• Freely accessible (i.e. non-commercial with no cost to users or membership fees)
• That described itself as being intended for patients and the public
• Broad in scope (not limited to specific conditions or types of treatments)
• Explicitly based on systematic reviews (i.e. there had to be a description of how the information is prepared and the description had to include a statement about using systematic reviews)

We identified websites that potentially met those criteria by considering websites that we and our colleagues (see Acknowledgements) knew of. The first author (AO) searched for government sponsored websites in English speaking countries (including Australia, Canada, Ireland, New Zealand, the UK, and the USA); searched Google for “health information” and “patient information” to identify websites that are frequently accessed for health information; and checked links to other websites on the websites that were identified. On 29 January 2018, AO conducted a final set of searches using the following terms: “health information”, “patient information”, “evidence-based health information”, and “evidence-based patient information”; and these search engines: Google [ 3 ], Bing [ 26 ], DuckDuckGo [ 27 ], and HONsearch patients [ 28 ]. Google and Bing are the two most popular search engines, DuckDuckGo is not affected by your previous search history, and HONsearch searches “trustworthy” health websites. The first 20 hits for each search were screened, and any websites that looked like they might meet our inclusion criteria were checked.

AO assessed each identified website for inclusion and the second author (EP) checked those judgements using information provided on the websites. In addition, we emailed each excluded website to confirm that our reason for excluding it was correct.

AO collected the following information for each included website:

• The stated purpose
• A statement that information about treatment effects is based on systematic reviews
• Availability of links to the systematic reviews
• Reporting size of effects
• Reporting certainty of the evidence; i.e. a judgement using GRADE (Grading of Recommendations Assessment, Development and Evaluation) [ 29 – 31 ] or another formal approach or an informal judgement about how sure we can be about the reported effects
• Availability of links to ongoing trials
• Information about how up-to-date information about treatment effects is
• What other information is provided
• What tools there are for searching, sorting, and filtering information
• Use of plain language (i.e. summaries written for patients and the public) and the availability of a glossary

EP checked all of the information that was recorded and the judgements that were made. To inform these judgements, both authors independently searched each included website for eight questions about treatments to assess the ease of finding information (AO on 22 December 2017 and EP on 9 January 2018). We selected the eight questions by searching Google for “common health questions” and selecting the first relevant list that we found ( 25 Questions About Your Health Answered - Oprah.com ). Many of the questions in that list were not about treatment effects and we modified some of the questions with the intention of having a variety of questions for different types of conditions and treatments. Table  1 shows the original question from that list, our question, the conditions, the treatments, and the initial search terms that we used to find information about treatment effects on each website.

Questions about treatments used to assess the included websites

We then independently assessed what was reported about treatment effects, the consistency of reporting, and the advantages and disadvantages of each website. Disagreements were resolved by discussion. Based on these assessments and the information we had collected for each website we suggested how the websites could be improved and provided tips for website users.

For each question, we searched for information using plain language terms without Boolean logic (using the first terms shown for each question in the last column of Table ​ Table1). 1 ). We recorded the number of hits for each search and each relevant summary that we found. We assessed the search as easy if we found relevant information using plain language terms without Boolean logic and the relevant information was one of the first few hits. We assessed searches as hard if we had to use technical terms or Boolean logic, or if we could not find relevant information; and as moderate if finding relevant information required some minor fiddling with the search terms or screening more than a few hits.

For each relevant summary that we found, we recorded whether any information was provided about benefits of the treatment and harms of the treatment, whether quantitative information was provided for at least one outcome, and whether a formal or informal assessment of the certainty of the evidence was provided. We then ranked the three websites for each question based on an overall assessment of how hard it was to find relevant information and the completeness of the information about the effects of the treatments.

We considered 35 websites for inclusion. Of these, 26 were excluded because information about treatment effects was not explicitly based on systematic reviews (Table  2 ), five were excluded because they were not intended for patients and the public (Table  3 ), and one was under development (Table  4 ). Three of the 34 websites met our inclusion criteria: Cochrane Evidence , Informed Health , and PubMed Health (Table  5 ). Cochrane Evidence and Informed Health produce content, whereas PubMed Health , which was discontinued in October 2018, aggregated content, including content from the first two websites.

Cochrane Evidence provides plain language summaries of over 7500 Cochrane Reviews, most of which are systematic reviews of the effects of treatments. The systematic reviews and the plain language summaries are prepared and updated by Cochrane review groups. Cochrane is a global independent network of researchers, professionals, patients, carers, and people interested in health, with over 37,000 contributors from more than 130 countries.

The plain language summaries include links to the full reviews. The full reviews are available in The Cochrane Library, which can be accessed for free in countries that have a national subscription or if the review or an update was published more than one year previously. The headings and content of the plain language summaries are inconsistent. The summaries include some background information, the authors’ conclusions, and links to other summaries that may be of interest. There is variability in the quality of the summaries. Some summaries include pop-up definitions (but not links to longer explanations) for some research and medical terms, and there is a glossary of terms relevant for Cochrane Reviews available on the Cochrane website. The summaries are translated into Chinese, Croatian, Czech, French, German, Japanese, Korean, Malay, Polish, Portuguese, Romanian, Russian, Spanish, Tamil, and Thai. The glossary is only in English.

No other information regarding treatments is provided in Cochrane Evidence , besides the plain language summaries of Cochrane Reviews. Cochrane website, where Cochrane Evidence is found has other information about the Cochrane Colaboration. Navigation tools for Cochrane Evidence are limited to a simple search for the entire Cochrane website. It is possible to sort findings by relevance, alphabetically, or by date of publication; and to filter the summaries by broad health topics and whether the reviews are new or updated.

Informed Health is the English-language version of the German website Gesundheitsinformation.de. The website is prepared by the Institute for Quality and Efficiency in Health Care (IQWiG) in Germany. IQWiG is a professionally-independent, scientific institute established under the Health Care Reform 2004.

The Informed Health website provides information about treatment effects together with other information for a wide range of topics. The website includes “research summaries” for some but not all treatments. “These are objective, brief summaries of the latest findings on a research question described in the title. They usually summarize the results of studies, for instance the results of one or (rarely) several systematic reviews or IQWiG reports. They also describe the study/studies in more detail and explain how the researchers came to their conclusions.” The website states that they “mainly use systematic reviews of studies to answer questions about the benefits and harms of medical interventions.” Links to systematic reviews are provided when these are used, but the reviews may not be freely available.

All of the research summaries that we examined (Additional file  1 ) included quantitative information about the size of the benefits, and they included frequencies for at least one outcome, but most often only for one outcome. The certainty of the evidence is not reported. All of the information is in plain language, written for patients and the public. There are hyperlinks to background information (but not pop-up definitions). There is a glossary of “medical and scientific” terms that includes primarily medical terms and few research terms.

In addition to information about treatments, Informed Health includes information about symptoms, causes, outlook, diagnosis, everyday life, where to learn more, and explanations (“Extras”) of topics such as how the body works, how treatments work, and types of treatments. Navigation tools for Informed Health include browsing by broad topic areas, an index (A to Z list) and a simple search. Search results can be sorted by relevance, the date information on the website was created, or the date it was updated.

PubMed Health specialized in systematic reviews of clinical effectiveness research. It included plain language summaries and abstracts of Cochrane Reviews; abstracts (technical summaries) of systematic reviews in the Database of Abstracts of Reviews of Effects (DARE) up to 31 March 2015; full texts of reviews from public agencies; information developed by public agencies for consumers and clinicians based on systematic reviews; and methods resources about the best research and statistical techniques for systematic reviews and clinical effectiveness research. PubMed Health was a service provided by the National Center for Biotechnology Information at the U.S. National Library of Medicine. It was discontinued October 31, 2018 “in an effort to consolidate similar resources and make information easier to find”. It included information from over 40,000 systematic reviews from a variety of sources, but plain language summaries were not available for most of those reviews. Links to the systematic reviews were provided, but not all of the reviews were freely available.

The reporting was inconsistent. Headings, reporting of effects, and reporting of the certainty of the evidence were inconsistent. PubMed Health had an extensive glossary (Health A – Z) and background information on drugs. Navigation tools included a simple search. Search results could be sorted by date of publication and filtered by Article types (including “Consumer information”); when information was added to PubMed Health , Content providers (including Cochrane and IQWiG); and Reviews with a quality assessment.

None of the three included websites includes links to ongoing trials and adverse effects are not consistently reported on any of the websites. All three include information about how up-to-date the information about treatment effects is.

PubMed Health was the easiest website to search, despite the large number of records that it includes. However, we had difficulties searching all three websites. We found information easily in Cochrane Evidence and Informed Health for one of the eight questions in Table ​ Table1, 1 , and for three of the questions in PubMed Health (Additional file 1 ). Conversely, it was hard to find information (or we did not find any information) for the five questions in Cochrane Evidence , six questions in Informed Health , and three questions in PubMed Health . It was not possible to use Boolean logic when searching Informed Health . This was possible on the other two websites, but none of the three provided any instructions or help for searching.

When we found information, it was consistently available about benefits, but only Informed Health consistently reported this information quantitatively in the plain language summaries. Quantitative information was provided in the linked scientific abstracts. None of the websites consistently reported information about harms or the certainty of the evidence, although Cochrane plain language summaries in Cochrane Evidence and PubMed Health frequently reported the certainty of the evidence. When the certainty of the evidence was reported using GRADE or another systematic approach, there was not a link to an explanation of what the grade means.

Overall we were most satisfied with Cochrane Evidence for 2 questions, with Informed Health for one question, and with PubMed Health for 3 of our questions. We did not find information about treatment effects on any of the three websites for two questions: “Should I stop using phone, tablet, computer, and TV screens before going to bed (for insomnia)?” and “Should I get my osteoarthritic knee replaced?” Informed Health provided advice for the first question (“For instance, it might help to only listen to relaxing music before going to bed and keep from talking on the phone or playing computer or mobile phone games”), but no reference to research evidence for that advice. We easily found relevant systematic reviews for both of these questions in Epistemonikos (Additional file 1 ).

We identified three websites for patients and the public that provide free information about treatment effects based on systematic reviews. A fourth, promising website, CureFacts, was under development (Table ​ (Table4), 4 ), and is still under development as of February 2019. Twenty-two other websites that provide free information for patients and the public claim to provide trustworthy, evidence-based information. However, it is not possible to know the extent to which the information they provide about treatment effects is based on systematic reviews, so is therefore less likely to be trustworthy. We considered four websites that provide access to systematic reviews, but none of these is intended for patients and the public (Table ​ (Table3). 3 ). Nonetheless, some people may find these useful, particularly Epistemonikos . It includes over 100,000 systematic reviews with the abstracts translated to Arabic, Chinese, Dutch, French, German, Italian, Portuguese, and Spanish. It is aimed for health professionals, researchers and policymakers but plain language summaries are not available for most of the reviews. Although it is not intended for patients and the public, it “has been used by well-informed lay people and journalists successfully” (Table ​ (Table3 3 ).

We did not consider databases that are not free, such as Trip Pro, which includes access to over 100,000 systematic reviews; or patient information from web-based medical compendia for clinicians, such as Best Practice , Dynamed , and UptoDate. We also did not consider websites that provide information for patients and the public based on guidelines, such as the UK National Institute for Health and Care Excellence (NICE) guidance for patients; or websites that are limited to specific conditions or types of treatments.

The three websites for patients and the public that explicitly provided information about treatment effects based on systematic reviews were likely to appeal to different people and their appeal may vary depending on the question being asked. We found that we preferred each of the websites for at least one of the eight questions we used as test cases (Table ​ (Table1). 1 ). We found PubMed Health somewhat easier to search, despite the large number of records it includes, and we found both Cochrane plain language summaries and Health Information research summaries when searching PubMed Health . Simple instructions regarding the use of Boolean logic and the use of quotations to limit searches would help improve the ease of use for all three websites. For example, the default for Cochrane Evidence appears to be to insert OR between words, resulting in large numbers of irrelevant hits.

All of the websites could be improved by more consistent use of headings and consistent reporting of both benefits and (especially) harms; inclusion of quantitative information about the size of the effects; and information about the certainty of the evidence based on the use of a consistent set of criteria, such as GRADE [ 29 – 31 ], and links to explanations of what the grades mean. Because many systematic reviews, including Cochrane Reviews, do not consistently provide this information, plain language summaries based on systematic reviews cannot always provide this information. However, they can alert users to the absence of trustworthy information about adverse effects, when this is the case, and it is possible to provide an assessment of the certainty of the evidence even when review authors have not done this [ 32 , 33 ].

All three websites provided plain language summaries of systematic reviews and all three had glossaries. However, none of the websites included both pop-up short definitions (which can be quickly accessed and read as scroll overs without having to go to another webpage) and links to longer explanations (that can be easily accessed when needed).

None of the websites included links to ongoing trials. This is something that, for example, NHS Choices does [ 34 ]. This is important because when there is important uncertainty about the effects of treatments, participating in a randomised trial may be the best option for patients [ 35 , 36 ].

We are not aware of any other studies that have attempted to systematically identify and evaluate websites that provide free access to information about the effects of treatments for patients and the public which is based on systematic reviews. There are thousands of websites that provide health information and we did not systematically screen all of these. Although we believe it is unlikely that there are other websites that meet our inclusion criteria, we did not consider websites for specific conditions or types of interventions, non-English language websites, or websites that were not freely accessible. Others might want to assess these and other sources of information about treatment effects in future studies.

"The evaluation criteria that we used were based on our judgement about what information is important and what is needed to make that information accessible. For example, providing a link to the systematic review enables people to go to the source of information about treatment effects for more information, if they desire. It also makes the basis of the information clear. Information about the size of effects and the certainty of the evidence is essential for making well-informed decisions. Basic search tools are necessary to make it easy to find information on the websites, and summaries that are written in plain language for patients and the public are more likely to be understandable than abstracts written for researchers or health professionals. Consistent headings, content, and use of language make it easier for users to become familiar with the websites and to find and understand information.

Our evaluation was based in part on searching for answers for eight treatment questions (Table ​ (Table1). 1 ). The criteria that we used to assess what we found for each question did not require a great deal of judgement. Consequently, there were only minor disagreements in our assessments (Additional file 1 ), and those were easily resolved. It is uncertain how representative what we found for those questions is for what would be found for other treatment questions, but we believe they provided a fair basis for assessing the websites. Moreover, we sent full drafts of this report to people responsible for each website and their corrections did not substantially alter our assessments or conclusions.

We did not evaluate the readability of the plain language summaries and, although we described other information that each website provides, we did not evaluate whether the websites provided other information that patients and the public want or need to make informed decisions; for example, information about other treatment alternatives, costs, and people’s experiences with the treatment [ 37 , 38 ]. We also did not evaluate how users of the websites experience them [ 39 ]. All of these are potential areas for future research."

Conclusions

It is possible for patients and the public to access trustworthy information about the effects of treatments based on systematic reviews using two of the three websites included in this review. However, all three of these websites could be improved and made more useful and easier to use by consistently reporting information about the size of both the benefits and harms of treatments and the certainty of the evidence, and by making it easier to find relevant information.

Searching the three websites frequently yielded much irrelevant information. Users can limit searches by using Boolean logic - inserting AND between terms (e.g. for the condition and for the treatment) and quotation marks to indicate that words need to be next to each other; e.g. “back pain”. However, this is unlikely to be obvious to novice users. Some users may want to use sources that are not intended for patients and the public, such as Epistemonikos , if they are unable to find information on one of these websites. They also might want to consider searching for ongoing trials, if there is important uncertainty about the effects of relevant treatments.

There are many other websites that claim to provide evidence-based or reliable information about treatments, but it is difficult to assess the reliability of the information about treatment effects provided on those websites since they do not explicitly base that information on systematic reviews.

Evaluating Digital Sources

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Because so much information is now available online, it’s important to know how to navigate digital sources versus print sources. Today, almost every print source has a digital edition (e.g., ebooks, online newspapers), and some academic journals only publish digitally. However, despite the many credible digital sources available today, there are still many unreliable sources available on the internet. Below are some suggestions for evaluating digital texts and a breakdown of the different types of sources available online.

Example of just one fallacious quotation that can be found online.

Search Engine Optimization

Search engine optimization (often abbreviated SEO) is a strategy used to increase unpaid views on a website from search engines. By using an algorithm, SEO works by locating keywords and sorting information for relevancy and accuracy. For example, if you were to search “How to change a flat tire” in a search engine, you would most likely get how-to videos and pages, rather than someone selling their car on Craigslist, because the algorithm sorts the webpages based on the keywords you input.

Different search engines may utilize SEO differently, which also means that, depending on what search engine you use, you might have different results appear first. For example, companies that are owned by Google will most likely appear first when searching for something on Google. However, if you used a different search engine, such as Yahoo or Bing, your results may differ.

Understanding SEO is important because it dictates the initial information you’re presented with when using a search engine for your research.

Differences in Domain Extensions

Different websites have different domain extensions, that is, the final string of letters following the period on a website’s domain name. Domain extensions help differentiate the type of websites and the different purposes they serve.

Below is a breakdown of the most common domain extensions:

• .com ⁠— a commercial website
• .gov ⁠— a government owned/operated website
• .org ⁠— a website associated with an organization
• .edu ⁠— a website associated with an educational institution
• .net ⁠— a website used by network providers

While there is no universal rule for whether a website’s domain extension makes it credible, it’s important to know that .com, .org, and .net domain extensions can be purchased and used by anyone. However, the .edu domain extension is reserved only for educational institutions, and the .gov domain extension is only used by governmental institutions.

Determining a website’s credibility can be especially confusing for websites with a .org extension that appear to have a governmental or educational affiliation. For example, the website passportUSA.org appears to contain official instructions for applying for a passport online; however, it is simply a PDF editing site. Because of the .org domain extension, it appears more credible.

On the other hand, some well-known organizations use a .com domain extension. Both National Geographic and TED use .com domain extension, despite the fact that they’re large organizations.

It’s important to not necessarily evaluate an online source simply based on its domain extension. As you navigate through different sources, you need to examine the authors and the website’s other credentials before making assumptions simply by the domain extension.

Wikipedia is a free online encyclopedia, created by the Wikimedia Foundation. Like other encyclopedias, Wikipedia can provide valuable information about certain topics. However, unlike encyclopedias, Wikipedia pages can be edited by anyone, which means that sometimes the information stated is not reliable and is edited for the sake of making a joke (see example below).

An example of a Wikipedia page that has been vandalized to include a joking reference to the film  Fight Club. Though this sort of vandalism is rare, it is not unheard of.

In fact, even Wikipedia itself encourages its users to take caution when gathering information from its site. It states: “Users should be aware that not all articles are of encyclopedic quality from the start. Indeed, many articles start out by giving one—perhaps not particularly evenhanded—view of the subject, and it is after a long process of discussion, debate, and argument that they gradually take on a  consensus  form. Others may become caught up in a heavily unbalanced viewpoint and can take some time—months perhaps—to regain a better-balanced consensus” (see “Researching with Wikipedia” ).

While it’s not encouraged to use Wikipedia as one of your main sources, Wikipedia can be used as a jumping-off point for other sources. At the bottom of most Wikipedia pages, you can find a list of sources that will take you to other pages (see image below).

An example of a References section from a Wikipedia article that has been carefully sourced.

Clickbait is a type of sensationalized advertisement that seeks to attract viewers through catchy or seemingly unbelievable headlines. Most sites that use clickbait use it to simply gain “clicks” on their site.

When looking for sources online, it’s important to recognize which article titles sound like clickbait. Most clickbait articles want to shock the reader, so be aware of words like surprising , alarming , and shocking in titles. Another form of clickbait is a page that challenges the viewer to a quiz or test. These will entice the reader by stating that the reader probably cannot answer each question correctly.

An example of a sensationalistic clickbait headline.

Understanding which articles are clickbait helps you evaluate your sources for credibility. Because clickbait sources exist simply to promote webpages, they are not considered credible sources.

Social Media

Social media is simply defined as any type of digital space that allows users to create content and share it with others in a social setting. A few of the most common social media platforms are Facebook, YouTube, Twitter, LinkedIn, Tumblr, and Instagram. While social media is not regularly used as a source in research, sometimes you might use a YouTube video or a tweet from a well-known individual.

When evaluating social media sites, it’s important to know more about a user beyond their username. For example, if you were interested in examining how scientists use Twitter as a platform, you might find yourself quoting a tweet by Bill Nye or the physicist Brian Cox. Both of these individuals have blue checks next to their Twitter handles, which means the accounts are verified. However, you might not want to quote a tweet by someone with an anonymous name and a Twitter handle such as @iluvscience321. 

Similarly, YouTube videos can either be posted by a large organization or a single user. If you are interested in using a YouTube video in your research, look at whether the publisher is a larger organization (such as TED or National Geographic) or a single user that only publishes under a username. While not all large organizations produce unbiased information, more well-known organizations will most likely provide more credible information.

In general, while you will probably not use a lot of social media in your research, if you do, try to locate the people or groups behind the usernames. After you identify the person or organization, you can find out more about them and determine their credibility.

Personal Websites

Many people have personal websites, such as blogs, that are not associated with a larger group or organization. Blogs can range in subject, from seasonal fashion tips to discussing every one of Emily Dickinson’s poems. When evaluating a personal website, find out what you can about the author and their affiliations. Some personal websites exist solely to spread propaganda or other biased information.

Podcasts are becoming a much more popular digital medium today. Podcasts are essentially audio files that can be streamed on a computer or mobile device, like portable radio. They are usually part of a series or follow a theme.

Like YouTube videos, podcasts can be valuable resources if used correctly. While almost anyone can produce a podcast, and topics range from discussing tv shows or books like The Bachelor  and Harry Potter , other podcasts give in-depth information about science, history, anthropology, and a wide variety of other topics. For example, podcasts like Stuff You Missed in History Class  and Historium Unearthia  provide information on often-overlooked historical events.

Like most sources, you should try to find out information about the author and cross-check the information in the podcast to see if you can find it elsewhere. Because anyone can produce a podcast, be aware that biased podcasts exist, and some might be used as propaganda.

Online News Articles

It’s possible to find many news articles online, both from digital newspapers and websites that post news articles. When examining online news articles, find out what you can about the organization behind the articles. Different news outlets may have different agendas attached to their reporting. For example, some websites are known for being more left-wing or right-wing.

Online Databases

Often, the most reliable information you will find on the internet will come from online databases. A database is a large collection of data, usually about one specific topic or idea. Some databases contain a broader field of information, while some are narrower. For example, Hoosier State Chronicles is a database that only houses Indiana newspapers, while JSTOR is a database that holds a wider variety of journals and books.

When looking for online sources, using a database helps you find credible information. In order for a source to be included in a database, it usually must go through a screening process that requires individuals to verify the information in the text. Because of this cross-checking process, the articles you find in databases will usually be more reliable than sources you might find simply by looking for them using a search engine.
