Think carefully about the sources you are finding and using. Here are some tools that can help:
Currency - How recent is the information?
Reliability - What kind of information is included in the resource? Is it balanced? Does the creator provide references or sources for data or quotations?
Authority - Who is the creator or author? Who is the publisher or sponsor? What is the author's or publisher's interest (if any) in this information?
Accuracy - Is the content readable? Is the content truthful? Is the content correct?
