Evaluating Web Sources


Look at the URL for signs of authorship

  • Is it a personal site? Look for the presence of the symbol "~".
  • What domain is it from? .org, .edu, .gov, .mil, .com, .net
  • Can you tell what entity or organization publishes or manages the site? At the beginning section of the URL, look for company or main site names. Try to find a link on the main site that tells you about the author or company ("about us" or "about me").

    Additionally, go to the Who Is Search site and enter the main part of the URL( called the domain name). You might be able to find information about the creator of the website.

    For magazine articles, use Ulrich’s Periodical Directory to find information about the magazine, newspaper or journal.

  • Look at the Web page for signs of credibility (actually read the text)

  • Is there an author listed?
  • Is the material dated?
  • Does the author give you information about him or herself including credentials?
  • Has the author or organization listed sources that were consulted? Are there links to other sources of information?
  • Does the page provide more than one viewpoint on the subject?
  • Can you tell the intentions of the web site? Is the purpose to inform, explain, persuade, sell, share, or entice? Is the information meant as satire or parody?


    Search the Internet for signs of credibility

  • Who links to this site? Go to most search engines, such as Google and type the following search: link:all.or.part.of.url
  • Look in a subject directory on the Internet (directories are often created by knowledgable staff members, such as subject experts and librarians). Is the page rated in a directory, such as Librarians' Internet Index, Internet Public Library or Yahoo's Search Directory?
  • Look up the name of the author in a search engine for biographical information or other publications. If you cannot find biographical information on the World Wide Web, try searching for the author in one of our Article & Research Databases.
