New College Writing Program Library Guide: Evaluating Sources

ASU Library Evaluating Sources Tutorial

Evaluating Sources - Overview

Evaluating the sources you are finding is an essential part of the research and writing process, and one of the main reasons putting together a research based project is recursive. That is, at any point in the research process, you may find a need to change your research question based on the information you are finding and retrieving. To that end, we recommend that you consider the following when evaluating your sources: 

1. Credibility: Who wrote it? What credentials does the author (or authors) hold? Who published the work? Is the work self-published, published by a university press, large corporation, or what? 

2. Audience: Who is the text written for? A general audience? A specialized audience? How do you know? Will the focus work for your topic? For your purpose? 

3. Support: Look at the bibliography and footnotes. What: there isn’t a bibliography? If the author does not provide support of his or her own, what evidence do you have that the work is reliable? How will you use the information? 

4. Objectivity: Does the text appear biased or is the author attempting to be fair? 

5. Newness: When was the text published? Is the information current or out-of-date?
