Both scholarly and peer-reviewed articles are written by experts in academic or professional fields. Scholarly articles are published in journals for specific academic disciplines. Many scholarly journals are also peer-reviewed.
Peer-reviewed articles are submitted to reviewers who are experts in the field. Because the reviewers specialize in the same scholarly area as the author, they are considered the author’s peers (hence “peer review”).
Both scholarly and peer-reviewed articles are excellent places to find what has been studied or researched on a topic, as well as find references to additional relevant sources of information.
