Tips for students of information technology

Evaluating Web Resources

The Web offers a wealth of information, but not all of it is equally accurate or reliable. Evaluate and cite your sources carefully.

Concepts and questions to consider:

Authority

  • Is the author of the page clearly identified? What are his or her credentials for writing on this topic?
  • Is the author affiliated with an organization? What is the reputation of that organization?
  • Is there a link back to the organization's page or some other way to contact the organization and/or verify its credibility? (address, phone number, e-mail address?)
  • Who publishes and/or is responsible for the website itself? Who has registered the URL? more info

Purpose & Coverage

  • Are the purpose and objectives of the page clear?
  • Is it geared to a particular audience or level of expertise?
  • Is the primary purpose to provide information? to sell a product? to make a political point? to have fun? to parody a person or organization or idea?
  • Is it a comprehensive resource or does it focus on a narrow range of information? Is it clear about this focus?
  • If it's an information database, are the dates of coverage clear and appropriate to your needs? Is it easy to search? Does it present information in a usable format?
  • If the page is interactive (a database or simulation, for instance), does it effectively present the information in a usable format?

Accuracy

  • Is the page part of an edited or peer-reviewed publication?
  • Does the content of the page convey the amount, depth, and significance of the evidence being presented? Are the arguments persuasive?
  • Can factual information be verified through footnotes or bibliographies to other credible sources?
  • Has the site been evaluated by one of the Web subject indexes, a rating service or a library? If so, can you tell what criteria they used?
  • Did you find this source using an internet search engines such as Google or Yahoo? They neither select the best pages nor filter out questionable ones, so you need to evaluate the choices carefully. They also may not always have the most recent version of the page.
  • Based on what you already know about the subject (or have checked from other sources), does this information seem credible?
  • Are there obvious typos or misspelled words or other signs of sloppiness?

Timeliness

  • Is it clear when the information was published?
  • When was it last updated?
  • Is this the most recent version?
  • Are there any indications that an attempt is made to keep the pages current?
  • If there are links to other Web pages, are they current?

Integrity of the Data

  • Is the source of any factual information clearly stated?
  • Are the source, scope and date of any statistics clearly labeled?
  • Is it clear whether or not the information as been excerpted from a larger piece?
  • Is there a way to tell if this is the most recent version of a particular piece?
  • Does the page rely on photographic images to make a point? If so, be aware that digital images can be easily manipulated.

Objectivity or Point of View

  • Does the page display a particular bias or perspective? Is it clear and forthcoming about its view of the subject? Does it use inflammatory or provocative language?
  • If the page contains advertising, are the ads clearly distinguishable from the content?
  • Is any conflict of interest discernable between content and advertising?
