Critical Evaluation of Sources

No matter where you find information you must determine if it is a credible and reliable source to use for research. Use the following criteria to evaluate:

 

AUTHORITY

Who is the author?  Is having a name enough?  Is the person an authority in this field? Establishing authority (credentials of the author) should be the first step in evaluation.  If you cannot find an author’s name, seriously reconsider using that source.  Remember also that an author can be an organization, government agency, advocacy group, etc.

 

       CURRENCY

Can you tell how current the information is?  When was it last updated?  Can you even FIND a date? If something about the topic has changed (a new law, a person was executed, etc.) since the page was revised, you could be using wrong information in your paper.  Always double-check with another source to make sure you’re getting the latest information.  If you cannot pinpoint a site’s currency, don’t use it.

 

FACTUAL OR BIASED?

Most sites will have some inherent bias.  Is it a commercial site? If they are only trying to sell something, proceed with caution.  .orgs are great sources of information, but are biased by their very nature (Planned Parenthood, Right to Life, e.g.).  This doesn’t mean you can’t use them – just be aware of the bias, and balance it with more objective, factual pages whenever possible (American Medical Association, WebMD, e.g.).

 

                                                 SCHOLARLY OR POPULAR?

Remember your Magazines vs. Journals handout?  Same principles apply here.  The information may be completely accurate and reliable, but if it was written for a non-scholarly audience, it may not be the best choice for a research paper.  .edus are good sources of scholarly information, though this will vary.

 

UNIQUE INFORMATION?

Did you find the site after you had done all your library research with books and databases? Does this piece contribute something unique your paper?  Does it offer something that other sources do not?  After having evaluated for all the above criteria, don’t select it simply because it’s “on my topic”.  Make sure that it contributes to the overall balance of your paper.
