Assessing Information on the Internet


Five main categories to consider

There are five main categories to consider when evaluating all information sources: purpose, coverage, authority, accuracy and currency.


Purpose

  • What is the purpose?
  • Who is the target audience?
  • What is the subject matter?

Coverage

  • Is there a range of different subjects covered?
  • What is the level of detail?
  • Is the source comprehensive?

Authority

  • Is the individual or organization reputable?
  • Is there contact information?
  • Who developed the site?
  • Notice the domain aspect of the Web address:
    • "edu" - Education sites or academic institutions.
    • "gov" - Government agencies/non-military.
    • "org" - Used by organizations and includes nonprofits.
    • "com" - Commercial or corporation sites.
    • "us" - often cities, or counties within the United States
    • "net" - networks, internet service providers, organizations.
    • "mil" - U.S. military sites and agencies.

Accuracy

  • Are there any typographical, spelling, or grammatical errors?
  • Are the data primary or secondary?
  • Does the information appear to be valid and well researched?
  • Is the information fact, opinion, or propaganda?
  • Is the language free of emotion-rousing words and bias?

Currency

  • Is the information up to date? When was it last modified?
  • If the information is not current, is it relevant?

If it is a listserv

  • Is there an archive of the messages available?
  • Is the list open to non-members?
  • Who would you contact to get more information about the list?
