Grey Literature in Health

Critical Appraisal

Once information from grey literature sources is obtained, an additional challenge for the researcher is to determine the quality of that information.

Ideally, grey literature (especially unpublished Randomised Controlled Trials) should be appraised to the same standard, and using the same Critical Appraisal Tools as those used to evaluate black literature.

AACODS Checklist

Jess Tyndall, Medical Librarian and Head of the Gus Fraenkel Medical Library at Flinders University, developed the AACODS checklist (Authority, Accuracy, Coverage, Objectivity, Date, Significance) as an evaluation and Critical Appraisal Tool specifically for use with grey literature sources. 1
