Peer Review

Heather VanDyne

When going through the research process, one of the things you will see (or be asked to look for) is a scholarly or academic source. These are often terms used by instructors when giving their students assignment instructions. When you are tasked with providing scholarly sources, it typically means a source that has undergone peer review.

What is Peer Review?

Peer review is a pre-publication review provided by experts other than the author of a research or literature review article and the editor of the research journal to which the article has been submitted for publication. The experts assess the article, going beyond simple fact-checking. A peer reviewer seeks to ensure the article is presented in the context of what is already known, that the methods the researcher used are the right ones, and that the article contributes to the field by reporting new and important content. Based on their assessments, as there are usually between 2 or 3 peer reviewers, an editor may accept the article or turn it down for publication. If it is accepted, the author may be asked to make minor changes.

How do I know if a source is peer-reviewed?

As peer-reviewed publications are more likely to be trusted and used by students and researchers, many will tell you within the journal or periodical's description or the About page of their website. Simply look for a peer review policy under the journal’s publication details or its aim & scope. If you are looking at a database or library catalog, there is usually an icon or label indicating a source is a peer-reviewed article.

In scholarly and academic databases, peer reviewed is a standard filter, along with date range and source type.

This page in the journal Evolutionary Ecology’s “about” section discloses their status as a peer-reviewed publication.

Many academic and scholarly databases will contain a peer-review, or Peer Review Only as part of their advanced search features. You can also utilize this feature in a database’s results page, typically found above or to the left of the search results. Non-academic search tools, such as Google Scholar, don’t have a filter for peer-reviewed articles, and should be verified to ensure it did come from a peer-reviewed publication. To do this, you can look at your selected journal’s editorial page to see if they have a peer-review policy.
