Grey Literature for Physical Sciences

Grey Literature is essentially any document that hasn't gone through peer review for a publication. Regulations, conference proceedings or doctoral thesis and more...

Check points:

All sources of information should be viewed through a critical lens.  With grey literature, there are a few additional things to look for when evaluating your sources:

  • Consider the tone of the document.
  • If statistics are included, are they cited?
  • Is there a bibliography at the end of the report?
  • Finally, is the document well written?

If you are uncertain about one of your sources, contact a librarian.
