Peer-reviewed journals (also called scholarly or refereed journals) are a key information source for your college papers and projects. They are written by scholars for scholar and are an reliable source for information on a topic or discipline. These journals can be found either in the library's online databases, or in the library's local holdings. This guide will help you identify whether a journal is peer-reviewed and show you tips on finding them.
Peer-review is a process where an article is verified by a group scholars before it is published.
When an author submits an article to a peer-reviewed journal, the editor passes out the article to a group of scholars in the related field (the author's peers). They review the article, making sure that its sources are reliable, the information it presents is consistant with the research, etc. Only after they give the article their "okay" is it published.
The peer-review process makes sure that only quality research is published: research that will further the scholarly work in the field.
When you use articles from peer-reviewed journals, someone has already reviewed the article and said that it is reliable, so you don't have to take the steps to evaluate the author or his/her sources. The hard work is already done for you!
If you have the physical journal, you can look for the following features to identify if it is peer-reviewed.
Masthead (The first few pages): includes information on the submission process, the editorial board, and maybe even a phrase stating that the journal is "peer-reviewed."
Publisher: Peer-reviewed journals are typically published by professional organizations or associations (like the American Chemical Society). They also may be affiliated with colleges/universities.
Graphics: Typically there either won't be any images at all, or the few charts/graphs are only there to supplement the text information. They are usually in black and white.
Authors: The authors are listed at the beginning of the article, usually with information on their affiliated institutions, or contact information like email addresses.
Abstracts: At the beginning of the article the authors provide an extensive abstract detailing their research and any conclusions they were able to draw.
Terminology: Since the articles are written by scholars for scholars, they use uncommon terminology specific to their field and typically do not define the words used.
Citations: At the end of each article is a list of citations/reference. These are provided for scholars to either double check their work, or to help scholars who are researching in the same general area.
Advertisements: Peer-reviewed journals rarely have advertisements. If they do the ads are for professional organizations or conferences, not for national products.
When you are looking at an article in an online database, identifying that it comes from a peer-reviewed journal can be more difficult. You do not have access to the physical journal to check areas like the masthead or advertisements, but you can use some of the same basic principles.
