How Do I Know the Articles I Found Are Peer Reviewed?

While several databases such as 1Search or Academic Search Premier give you the option to choose a checkbox to "limit to articles from peer-reviewed publications," these checkboxes are not fool proof.  Use two out of the following three methods on this page to determine if the articles you have found are peer-reviewed.  First, either check the journal's website or use the database to find out if the journal uses the peer review process to edit articles.  Finally, always check that the article itself is peer reviewed and reporting on original research by looking for specific characteristics of the article.

Use the Journal Website

One of the best places to find out if a journal is peer-reviewed is to go to the journal's website (just Google the journal title).

Most publishers have a website for a journal that tells you about the journal, how authors can submit an article, and what the process is for getting published.

If you find the journal's website, look for the link that says "information for authors," "instructions for authors," "submitting an article" or something similar.

Use the Databases

Another place to find out if the journal is peer-reviewed is to use one of the online databases.

For example, if you know that articles from your journal appear in the Academic Search Premier database, you can search for the journal in the database and learn more about it.

Go to Academic Search Premier and click on Publications at the top of the screen.

Search by publication

Enter the name of the journal and click browse. If the journal is included in the database, you will see it in the list of results.

Search for the publication

This will take you to the journal information. At the bottom, you can see that this journal is peer-reviewed.

Academic Search Premier does not include all journals so the one you are looking for may not be listed here. You can also try Academic OneFile and browse for the publication.

Look at the Article

Peer reviewed articles are research articles that have been evaluated and approved by other experts in the field before being accepted for publication in a journal. They almost all follow a predictable pattern and contain the following elements:

1. AUTHOR:  The author is always listed with the credentials that identify the author's expertise, such as university or research affiliation.  The author often holds a Ph.D. in the subject area of the article. Contrast this to an author who writes on many different topics (like in a magazine or newspaper).

2. LANGUAGE:  The article language tends to be formal and technical, and is particular to the discipline in which it is written.  It is geared to other researchers in the same subject.  Contrast this with popular articles that are written at an informal and basic level for easy understanding by the general public.

3.  CONTENT:  There is an abstract at the beginning of the article which summarizes the content.  The articles almost always follow the pattern of having introduction, methods, results, discussion, conclusion, and bibliography sections. News articles, scientific letters and book reviews do not follow this pattern. 

4.  ORIGINAL DATA:  Original data will be presented in charts and graphs illustrating the results of experiments. Contrast this to a news feature, which pulls together results and ideas from other researchers' work.

Evaluate Your Source

  • Does the source have a bibliography? This can lead you to other sources.
  • Is there an author listed as part of the citation? Judging authority can be difficult without an author.
  • Is the journal refereed (peer reviewed)?
  • How old is the source? Will this matter for your topic? Currency of information can be important. Some aspects of a topic may need currency more than others.
  • What other terminology is being used either by the author or by the database? Keep an eye out for other words you can use in your search statements.
  • Do the OSU Libraries own the journal (either in print or electronically)? If we don't own it, it will take more time to get your hands on the source.
