A major challenge in a time of Info-Glut and Info-Garbage is evaluation of information sources.Before basing a decision on the information available, wise researchers (and students) will give thought to the following criteria:

• reliability - definition | accuracy - definition | authority - definition
• currency - definition
• fairness - definition
• adequacy - definition
• efficiency - definition | organization - definition

Staff and students need to learn to apply these concepts critically to the sites they are visiting so they become thoughtful and discerning information consumers. A healthy amount of scepticism is warranted.

Using a table as a "visual organizer" often helps focus the evaluation of sources. List the site or source on the top and then rate each source from four asterisks to one asterisk.

**** Excellent *** Good ** Satisfactory * Weak

	Source One	Source Two	Source Three
reliability - accuracy - authority
currency
fairness
adequacy
efficiency - organization
