Make Sure and Evaluate All Websites

Currency: the timeliness of the information

  • When was the information published or posted?
  • Has the information been updated or is it out-of date for your topic?

Relevance: how does the information meet your needs

  • Does the information relate to your topic or answer your question?
  • Is the information at an appropriate level (i.e. not too elementary or advanced for your needs)?
  • Have you looked at a variety of sources before determining this is one you will use?

Authority: the source of the information

  • Who is the author/publisher/source/sponsor?
  • Explain how the author is an authority or an expert. Can you find their credentials, where they work, their education level?
  • Is there information on the organization or person publishing the website? Is there an About Us?
  • Does the URL reveal anything about the author or source?.com (commercial), .edu (educational), .gov (U.S. government), .org (nonprofit organization), or .net (network)

Accuracy: the reliability, truthfulness, and correctness

  • Where does the information come from?
  • Is the information supported by evidence?
  • Has the information been reviewed or refereed?
  • Can you verify any of the information in another source or from personal knowledge?
  • Does the language or tone seem biased and free of emotion?

Purpose: the reason the information exists

  • What is the purpose of the information? to inform? teach? sell? entertain? persuade?
  • Do the authors/sponsors make their intentions or purpose clear?
  • Is the information fact? opinion? propaganda?
  • Does the point of view appear objective and impartial?
  • Are there political, ideological, cultural, religious, institutional, or personal biases?

About Using Wikipedia

Wikipedia is a great tool for a summary of a topic. Wikipedia content is constantly revised, and entries vary in quality. Some of the content is excellent, some is questionable.

How can you use Wikipedia in a way that benefits your research process?

  • Scan the article to get general information and terms you can use as keywords for further searching.
  • Scan the article for references and view the External Links. Sometimes these can lead you to excellent books or articles that you can find in the print or digital resources of the Keefe Library or Boston Public Library.
  • Don't reference Wikipedia articles in your paper.
  • As you read Wikipedia articles, you may read notations that call for more evidence, or call attention to bias. These are very constructive principles that highlight some of the areas of improvement needed in an article.

Many educators frown on the use of Wikipedia. Why?

  • Wikipedia content is not necessarily written by subject experts, and may be inadequate or incorrect.
  • Articles in Wikipedia may be changed or deleted between viewings.
  • For research papers, you need authoritative resources, so it is absolutely necessary to consult other sources. 
  • Anyone can search Google or find a Wikipedia article. To demonstrate academic skill, it is important to go beyond these basic tools.
