What is a peer-reviewed article?
Peer-reviewed articles have been evaluated by several researchers or subject specialist in the academic community prior to accepting it for publication. Also known as scholarly or refereed.
Verify that a journal is peer reviewed (refereed) by looking up the journal title in Ulrich's Periodicals Directory.
Remember that there may be content in peer reviewed journals which is not peer reviewed. These may be book reviews, letters, or front and back matter. In most cases, though, the research articles within will be peer reviewed. Consult a librarian if you're not sure.
