Peer-reviewed articles (also know as refereed) go through a process where they are analyzed by experts in a field before publication.
Articles can be scholarly (written and published for an academic audience), yet not go through the peer-review process.
Step 1: Check the peer review status of the JOURNAL.
Search for your title in Ulrichsweb Global Serials Directory.
When you find your journal, look for a "referee shirt" symbol. The symbol will appear next to any journal title that is peer reviewed and/or refereed (interchangeable terms).
Step 2: If the JOURNAL is peer reviewed, then assess the ARTICLE.
Is it a full research article? If your article is a short news brief, an editorial, a letter to the editor, or a re-print of a conference proceeding, it is not peer reviewed.
