This document provides guidance on evaluating research sources. It recommends checking who wrote the source, its scope, where and when it was published, and how the information is presented. It also suggests looking at an author's credentials, additional writings, and reference lists. Books should clearly indicate the author and credentials. Bibliographies and notes can lead to more sources. The scope defines the topic's breadth. Bias should be considered by checking the publisher, author affiliations, and date. More recent sources are generally better. Conclusions should be clearly stated and citations and references properly formatted.
