Articles published in peer-reviewed (refereed) journals have been through a formal approval process, which checks that the article is accurate, well-researched, and contributes to the body of knowledge in the field.

They are regarded as being of a higher quality than articles in journals that aren't peer-reviewed. You will sometimes be instructed to use peer-reviewed articles.

How do you know if an article is peer-reviewed?

• You can often use refiners in Primo Search and databases to limit your search results to peer-reviewed articles.
• Another way to check if a journal is peer-reviewed is to check its editorial information on its website.
• But the best way to check or confirm that a journal is peer-reviewed is to use Ulrichsweb Global Periodicals Directory:

1. Search for the journal title (not the article title), or the journal ISSN 
2. Locate the journal in the results list
3. If there is a referee's shirt icon () in the column on the left it means the journal (and therefore the article) is refereed (peer reviewed):

• A-Z Databases
• U-Databases
• Ulrichsweb Global Serials Directory
