Research Guides: Gateway to Media: Evaluate Your Sources

Critical Evaluation of Information Sources

In evaluating the credibility of an information source there are several key areas to consider:

the Authority of the author and the background of the publisher
the Objectivity of the author
the Quality of the work
the Currency of the work
the Relevancy of the work

The tables below provide a framework for investigating these aspects of an information source, whether it be an article in a journal or newspaper or encyclopedia; a book; a web site; a government document; or any other source upon which you're relying. Not all questions will apply in all situations, and not all responses need to be positive ones - this is not a scorecard. The questions are intended to help you think critically about information sources.
