Library Research Help Evaluating Web Sites

Evaluating Websites

The Internet offers a wide range of information and perspectives, much of it incorrect-- or, at the very least, incomplete or biased.

Consider the popular online encyclopedia, Wikipedia. Wikipedia offers a great deal of information-- most of it true-- but it is written and edited by unnamed authors. Professors tend to make disapproving faces at students who cite Wikipedia articles for their papers.

For the purpose of including information in a college-level research paper, a web source must meet certain high standards. Consider beginning to evaluate a web source by answering the following questions....

Questions of Authority

  • What are the qualifications of the author of the web page?
  • To what extent is the author recognized as an authority by others of established credibility?
  • What form of recognition is it? Published statement? Incoming link? Institutional affiliation?
  • Questions of Content

  • How comprehensive is the author's treatment of the subject addressed?
  • When appropriate, to what extent does the author satisfactorily address competing and alternate perspectives?
  • Questions of Currency

  • When was the page last modified?
  • When was the page first created?
  • Especially in dynamic fields of study (such as medicine and physics), to what extent does the author take into account recent developments in the field?
  • Questions of Reliability

  • What is the purpose of the web page?
  • To what extent can any of the web page author's statements be attributed to self-interest?
  • To what extent can any of the author's statements be verified by an authority from another source?
