Once you find a great article, one of the easiest methods of finding more great articles on the same subject is to look through the bibliography of the article and take note of other titles that look interesting to you. Once you have a citation, you need to be able to get to the actual article. The videos and links from this page will teach you how to go from citations to full text article!
Determine Peer-Reviewed Status
UlrichsWeb is a listing of journals that includes whether or not a journal is peer reviewed (aka refereed) or not. Simply open UlrichsWeb, type in the title of the journal, and look for a referee's jersey symbol (see symbol on right). If a referee's journal symbol appears next to the title, it is a peer-reviewed journal.
