Evaluating Scientific Sources

This guide provides resources and information for evaluating different kinds of scientific publications.

What is Peer Review?

Peer review is a process articles go through when submitted to certain academic journals. Thr process starts when an article is submitted to a journal by the author. The journal's editor then checks that the article fits with the scope of the journal. If the article passes this initial check, the editor then sends the article to the author's peers (researchers in the same discipline) for review. The reviewers evaluate the article based on the quality of the research, the validity of the data, the originality of the research, and the conclusions drawn by the authors. The reviewers provide their feedback to the editor, who will make the final decision about whether or not to publish the article. The editor can decide to accept or reject the article. If the article is accepted, it oftentimes requires revisions before it can be published. This process of peer review can take weeks, months, or years. Articles that have gone through this process are often considered high-quality by others in their field of study.

Identifying if a Journal is Peer-Reviewed

Going to the journal website is one of the best ways to find out if a journal is peer-reviewed. Most journals have a website that tells you about the journal. Once you find the journal website, look for information describing the journal, or look for information/instructions for authors, submitting an article, or something similar.
