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.
- Go to Ulrich's
- Enter the title of the journal (not the title of the article) in the search box
- If an icon appears by the journal title in the peer reviewed column, then the title is peer reviewed.
