Scholarly journal articles are articles that are written by experts in a given field and undergo a peer-review process. For example, a group of physicians may conduct research and write up their findings in a paper which is then submitted to a medical journal for publication. The editors of the medical journal will send that article to other physicians (peers of the authors) who will use their own medical expertise to review the article. The article may be accepted, accepted with revisions, or rejected. In this way, the article goes through a rigorous editorial process before publication and, if published, is considered reliable, authoritative and scholarly.
Scholarly, or academic journals contain peer-reviewed/refereed articles, as well as commentaries, news bulletins, announcements and reports that have not undergone the peer-review process. Therefore, a scholarly or academic journal may include items that are not refereed or peer-reviewed.
