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

How to Evaluate Resources
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.”

Grey Tech Approaches to High Tech Issues, Prague, Czech Republic Available from: http://archivesic.ccsd.cnrs.fr/sic_00581570/document.
It can be used to supplement books and journals when conducting research as it provides a different perspective and is commonly more current than different materials.
Examples of Grey Literature include:
- conference papers and proceedings
- government documents
- reports
- policy documents
