Not all published material has the same credibility. Peer-reviewed articles have more authority
because they have been scrutinized and approved by scholars in a particular field. Peer-reviewed articles/journals are sometimes called "refereed" articles/journals. To learn more, see this tutorial
There are several ways to identify peer-reviewed articles:
Limit database searches to only peer-reviewed articles
When searching for articles in databases, look for a search option for limiting to only peer-reviewed articles. In EBSCOhost databases, look for this option on the bottom half of the Advanced Search screen. There is no peer-review search limit option in PubMed or Web of Science.
Search Ulrich's Periodicals Directory
If you're ever unsure whether an article is peer-reviewed, you can look up the journal title in Ulrich's Periodicals Directory
. Select Title (Exact)
in the top right Quick Search
box and enter the name of the journal. A referee jersey icon
will appear next to the journal title if it is peer-reviewed.
