Loyola Notre Dame Library Evaluating Web Sites
When finding information on the World Wide Web, it is important to evaluate a Web site in order to determine whether it is a credible, reliable source to use for research purposes. You can evaluate the quality of a Web site by asking yourself the following questions:

1. Purpose & Content
  • What type of site is this? (i.e., commercial (.com), organizational (.org), educational (.edu), government (.gov), military (.mil), other?)
  • What is the purpose of this site? (i.e., to inform, to entertain, to advertise, other?)
  • What kind of information is the site providing? Is the information presented objective or biased?


  • 2. Author
  • Who created this page? Does the site even indicate who the author is? What are the author's qualifications or area(s) of expertise?
  • Is there a link to a "Mission Statement" or an "About Our Organization" page?
  • The information provided on such pages can indicate to you what side of an issue a particular organization is on, or help you to understand a company's values and principles, for example.
  • Is there contact information available from the site? Sometimes contacting someone directly, whether by phone or by email, is the best way to get specific information you may need, or to get recommendations for other resources you might consult to get further information.

  • 3. Currency
    When was the site last updated or revised? (Most important for topics that are subject to change frequently.) Is the site well-maintained, or are there many broken links, errors, etc.?
    A quality site will be well-maintained and updated as necessary.

    4. Design/Organization
    Is the site well-organized and easy to use? Can you find the information you need? Is the site slow to load or difficult to read? Sites that are not well-designed or organized my not be worth your time spent using them for research purposes, and, futhermore, may be unreliable resources.


    Libraries often link to quality Web sites from their home pages. For example, the Loyola/Notre Dame Library links to Web sites from the online Research Guides, as well as on the "Suggested Internet Sites" page. Another good source of quality Web sites is Librarians' Index to the Internet. These Web sites generally have already been evaluated by a librarian and selected as being good sources for particular subject areas or research needs. So, in a sense, the evaluative work has already been done for you. You can freely use these Web sites knowing that they are reliable sources. Still, you should evaluate even these sites to determine whether they are appropriate for your specific purpose.
