A peer reviewed article is an article that has been written by an expert and has been reviewed by other experts before being published. This review process ensures the quality of information in the article.
The Library subscribes to a large number of journals, newspapers and other resources. Not all articles are peer-reviewed, so you need to find a way to limit your results to peer reviewed articles.

I've found a great article, but I don't know if it is peer reviewed? By using a resource called Ulrich's International Periodical Directory, you can check to see if the journal that the article is from is peer-reviewed.
