Peer-reviewed or refereed journals are among the most respected sources of academic information. Both words mean the same thing.
Articles published in these journals are subjected to a strict approval process where experts on the subject review the article before it is accepted for publication. This process is designed to ensure the article is accurate, well researched, and contributes to the body of knowledge in a field.
How to find peer-reviewed journal articles
Library Search and many other databases and allow you to restrict your search to peer-reviewed journals. (In LIbrary Search you can keep this option active for your whole session by selecting Peer-reviewed Journals from your results page and then hovering over it in your Active Filters and clicking on the lock symbol that appears.)
Journals indexed in Web of Science are all peer-reviewed.
Use UlrichsWeb to check if the article you have is a peer-reviewed article. (Ulrichs calls peer-reviewed journals "refereed" journals).
