4. Currency- What is the date of publication?
5. Authority- Who is the author and publisher?

How to Evaluate Resources
Scholarly Versus Popular
Grey Literature
Grey Literature is
“…information produced on all levels of government, academia, business and industry in electronic and print formats not controlled by commercial publishing i.e. where publishing is not the primary activity of the producing body.”

- conference papers and proceedings
- government documents
- reports
