University of Oregon Libraries has a nice outline of how to evaluate if the source of information you are using is reliable. The questions to consider are in a table or matrix form. For example,
* Who is the author?
* Most common places to find authors’ names listed:
o Title page (book or report)
o Title information at top of first page (articles, book chapters)
o End of the article (encyclopedias)
o Top or bottom of page (web pages)
These examples are intended to underscore that there is no substitute for personal evaluation of information sources, whether in print, online, or in some other form. The questions below are ones you might ask about an information source – article in a journal, newspaper, or encyclopedia, book, web site, pamphlet, government document, food container, poster, interview subject, or any other source upon which you’re relying – in order to determine its credibility and suitability for your particular project. 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 merely intended to help you think critically about information sources.
