The vast majority of scholarly journals are "peer-reviewed" or "refereed." This designation refers to a process through which articles submitted to such journals undergo an editorial review by a group of academics or researchers whose knowledge and credentials are similar to those of the author's, i.e., the author's "peers."

Many article databases available in the Consortium Library, such as Academic Search Premier, allow you to limit your search to only peer-reviewed or scholarly publications. If your professor asks you to only use scholarly sources for your research paper, checking this box will limit the results of your search to only those journal titles that are considered scholarly.

For example, in Academic Search Premier the check box to limit to peer-reviewed publications appears below the search boxes:

Many other databases have a similar check box to limit your search results to peer reviewed publications.
