This document discusses the differences between popular and scholarly sources. Popular sources include magazines and newspapers, are written for a general audience by journalists rather than experts, and do not contain references. Scholarly sources include academic journals, are written by experts and approved by peer review, often contain original research, and cite other works. Both types of sources can be useful, with popular sources good for initial understanding and scholarly sources preferable for advanced coursework. The document encourages students who have questions to contact the St. Catherine University Library for assistance.
