Evaluate Information A.S.A.P.
Is a source worth your time and energy? Is it appropriate for your needs? Here is a way to evaluate all types of sources.
Author: Look for the author’s name(s), credentials, expertise, other work, reputation, recommendations
Sources: Look for a bibliography, works cited, or other list of sources the author used
Age: Look for the publication or copyright date. Is it current enough for your topic?
Publisher: Look for the name of the publisher (or parent website). What other kinds of sources does this publisher provide? What does a Google or Wikipedia search for this publisher say?
