Peer-reviewed journal articles (also called scholarly or refereed articles) are written by expert researchers and reviewed by other experts in the field. Peer review refers to a process in which information sources are examined and approved by a number of experts in that subject area before being published. Scholarly articles or books will usually be read by two or three academic reviewers who will suggest to reject or accept the article/chapters (with no, minor or major revisions) for publication. Peer-reviewed journal articles are often used as the main component of academic research. Using peer-reviewed material is a good way to make sure that the information you are receiving is creditable and correct.
