How to evaluate

Examine:

• Relevance

• Credibility

• Authority

• Currency

• Audience

• Bias

Relevance:

• Does the page answer your research question?

• IF NOT:

Reconsider your terms and search again.

Credibility:• Are there clues to factuality?

– Examine URL– Domain name extension (.com, .edu, .org, .ca, etc.)– Bibliography– References– Compare information with other sites– Electronic version of a reputable print source– See the “About us” section of the web site

Look for an “About Us” section.

Here it is called “About Refdesk.”

Click on the Mission Statement – Introduction/Tour

Here is a description of the author’s background.

What do you think of him as a resource?

The information appears to be factual, in statements of actuality or occurrence.

There are no statements of belief or feeling, no opinions.

The URL is a “.com” which indicates a promotional site or just an inexpensive one.

Click on drop down menu to access Reference material including dictionaries, encyclopedias, calculators, almanacs.

Authority:

• Who is responsible? (“about us” again)

• Where did the information come from?– Consider citations and sources again.

Currency:• Is the page current?

• When was it created and/or updated?

• The front page, the copyright date at the bottom, and “About Refdesk” provide information that the site is updated daily, weekly, and yearly.

Audience:

• For whom was this created? (e.g., consumers, professionals)

• Can you understand it?

• Is it too easy?

Bias:

• What is the purpose of the page?

• Is there a definite point of view?

• Is there an agenda?

• Consider the source.

Under “About Refdesk,” there is a vision statement and a link to a mission statement, which is much like the vision.

Another statement of purpose is in the description of the author where he states his goals.

Here, the Webmaster explains how the page is expensive. Then he appeals for donations which can be made through Amazon.com or PayPal.

With such commercial ties, users need to continue evaluating the site each time it is used.

Remember to Evaluate:

• Relevance

• Credibility

• Authority

• Currency

• Audience

• Bias
