Like any source, once information from grey literature is obtained it needs to be critically evaluated and appraised to determine the quality of the information. This is particularly important as grey literature has not usually received the same quality checking as peer reviewed published material.
Grey literature should ideally be appraised to the same standards as those used to evaluate any other literature.
AACODS Checklist
The ACCODS checklist provides five criteria for judging the quality of grey information (Authority, Accuracy, Coverage, Objectivity, Date, Significance) It has been designed as an evaluation and critical appraisal tool specifically for use with grey literature sources, by Jessica Tyndall from the Flinders University Medical Library. It is a useful tool to assist with assessing the quality of grey literature for your research.
