Grey Literature

What is Grey Literature?

Grey literature is literature produced by any organisation whose main purpose is other than publishing, such as governments, businesses, not-for-profits, health organisations and associations, and more. Since these organizations are outside the publishing model their publications are not usually indexed with traditional databases making searching for grey literature difficult.

Finding Grey Literature

Grey literature does not go through academic editorial processes, such as peer-review. You must critically evaluate any grey lit source you use.
