Evaluating grey sources

All information that is retrieved in any form for research must be viewed in a critical manner to ensure that it is credible. This is true with grey literature as it encompasses all forms of work, both physical and electronic.

See our guide:

The following evaluation checklist, proposed by Tyndall, covers points particularly important for evaluating grey literature -

AACODS (Authority, Accuracy, Coverage, Objectivity, Date, Significance) incorporates the following ideas:

  • Authority - Incorporates expertise, propriety, experience, credibility, reliability: it asks the question who is responsible for the intellectual content?
  • Accuracy - Does it seem to be right? Has it used a clearly stated methodology? Has it been peer reviewed?
  • Coverage - Try to be aware of any coverage limitations, stated or otherwise.
  • Objectivity - This incorporates opinion, expert or otherwise. Is it balanced or does it have an unstated bias?
  • Date - Does the resource have a clear date related to content?
  • Significance - Is it meaningful? Does it add context?
