Evaluating Sources for Authority

Consider Quality...

In academic research, use only high quality and authoritative sources. The authority of a source depends on the research question.


Does the site/document have an author? What are the author's credentials? Why should you trust this author as an expert? 


Who sponsors or publishes the source? What evidence demonstrates that the sponsor/publisher is credible? What purpose/perspective does the sponsor seem to promote?


How recently was the information posted or modified? Could it be outdated or obsolete?


How do you know that the information itself is trustworthy? Are there links to other sites/sources to support factual claims?


These principles of web source evalution are drawn from The St. Martin's Handbook8th edition (p. 218-219).
