Once you have launched your search, use the filters on the right hand side of the results screen. Check the Peer Reviewed filter under the Availability options and then expand the Resource Type filter options and select Articles. Click the 'APPLY FILTERS' button.

Please note that this peer reviewed limit is not perfect. Sometimes letters to the editor or editorials published in a journal receive this label in LibrarySearch but they would not be accepted by most instructors as peer reviewed articles. Our FAQ on identifying scholarly/peer reviewed articles walks you through what to look for.
