Accuracy:	factually irrefutable and complete information. Tip: Is there a second reliable source that gives the same information? Is it a peer-reviewed source. Does the publisher use editors and fact checkers?
Scope of Coverage:	the extent to which the source explores a topic. Scope of coverage may include a period of time, a geographic region, various aspects of a topic, etc. Tip: Does the source offer information about its scope?
Objectivity:	minimum bias with respect to interpretation or analysis of facts. Tip: Is the source trying to persuade you? Who sponsors or publishes the information? What can you discover about their intentions?
Timeliness:	information that is current at the time of publication. Tip: Does the source provide a date for this specific Web page or entry, as opposed to a general site revision date?
Authority:	a reliable source of information. Tip: Can you determine the name of the author and publisher? Is the author a recognized expert on the topic? What is the publisher's reputation?
Verifiability:	confirmation of the facts or information with a second reliable source. Tip: Does the material cite to its sources of information?
