Evaluating Sources

You will need to use critical thinking skills to evaluate your sources. This is especially true with online-only sources or non-academic journals.  Check the following:


  • Is the person, group or organization responsible for the site identified?
  • What type of site have you located?  For example, is it a personal page (.net) or blog, a company website (.com), an organization (.org), a government body (.gov), or an educational institution (.edu)?


  • Does the author cite reliable sources for his or her facts?
  • How does the information compare with that in other works written about this topic?


  • What are the author's qualifications for writing on this subject?
  • Is he or she connected with an organization that has an established reputation?


  • Does the web site include a publication date or "last updated" date?
  • Is the information provided recent? Or is it from the time period you are researching?


  • Is the author affiliated with a particular organization that might have a bias?
