A Print Page


Authority - is the author named? Is the source reputable?
Currency - how recently was the information published?
Relevance - is the information useful to you?
Accuracy - can the information be verified in other sources?
Bias - does the author have a specific purpose or agenda?



Be cautious if you can't find the author's name or credentials. An exception is a magazine or newspaper article written by an unnamed staff reporter. When there is no author given, the authority of the source is based on the reputation of the publisher or producer of the information. What is the author's level of education? Is he or she an authority on the subject? Is the author affiliated with a well-known organization, university, or government agency? For a web page, is it hosted by a reputable organization, or is it someone's personal web page? For original research, is it published in a peer-reviewed journal?
