Q. How can I tell if an article in PubMed is peer reviewed?

According to the U.S. National Library of Medicine, most journals in PubMed are peer-reviewed or refereed. However, the database does not list peer-reviewed/refereed journals, and you cannot limit your search to peer-reviewed journals using PubMed.  You can check whether a specific journal found listed in PubMed is peer-reviewed by using Ulrich's International Periodicals Directory, or contact the Reference Desk at 620-2616.
