How can I search for a peer reviewed article?
Once you have carried out a basic search on Library Search you can "Refine Results" by selecting Peer Reviewed Journals.
There are also a number of other limiters which can be set, such as date range, type, subject and data bases, which may help to refine your search results.
How can I check if an article is peer reviewed?
You will need to look at the journal information to find out if the articles it publishes are peer-reviewed. If the article is from a printed journal, look at the publication information in the front of the journal. If the article is from an electronic journal, go to the journal home page and look for a link to 'About this journal' or 'Notes for Authors'. Here it should tell you if the articles are peer-reviewed.
