As per ProQuest, Scholarly Journals can be defined as:
A scholarly journal is a publication that is authored by academics for a target audience that is mainly academic. The scholarly journal printed format isn't usually a glossy magazine, and it is published by a recognized society with academic goals and missions. The ProQuest criteria states the publication must be academic in focus with the intent to report on or support research needs as well as advance one's knowledge on a topic or theory. The publication will be targeted for professional or academic researchers and have in-depth analysis typically focusing on one discipline or academic field. The publication will likely be peer reviewed or refereed by external reviewers. The publisher should be a professional association or an academic press.
As per ProQuest, a peer reviewed journal can be defined as:
A publication in which articles go through an official editorial process that involves review and approval by the author's peers (people who are experts in the same subject area). Most (but not all) scholarly publications are peer reviewed. Some trade publications are peer reviewed.
