When: How old is the information?

Historical sources do not need to be updated unless new data is discovered.

What kind of research questions could you answer using these sources?
Are these resources reliable?

Why: Why was the information published?

Question the reliability of information if the author or sponsor attempts to convince readers to:
  • support a political agenda
  • adopt a point-of-view
  • purchase a product or spend money
  • financially support a cause
Scholarly resources should acknowledge multiple perspectives or points of view.

While the author may support one position, the existence of other viewpoints should be mentioned.

Do these resources present multiple points of view?
Would you use them in a research project? Why or why not?
