First things first: Find out what types of sources your instructor will allow you to use for the assignment. Some will only allow references from scholarly journals and books.
On second thought: If you are permitted to use web resources and newspaper and magazine articles in your papers and projects, you will want to evaluate the information to make sure that it is an authoritative and credible source (unless you are illustrating a point about them-- for example, showing depictions of women in the 1920s from a magazine).
Some things to consider in evaluating all types of sources*:
Currency: Is the information current and up-to-date?
Relevance: Does the information have anything to do with your topic?
Authority: Is it authoritative?
Accuracy: Is reliable and true?
Purpose: Why does the information exist?
Check the acronym. Did your website pass the CRAAP Test?!
