Grey literature : Evaluating Grey

Evaluating Grey Sources

It can be difficult to evaluate grey information. However, most of the same principles for black literature also applies to grey literature. Does the author seem credible and is the research referred to in other, relevant research references? Does it appear to be a well known author or expert in the field? Does the content seem accurate and well defined? Does it present good coverage of your specific information need(s)? These are very important questions and any researcher wanting to add grey information in their research, must critically appraise the literature they come across and decide what value and evidence it brings to the specific research question in mind.

Authority - Accuracy- Coverage- Objectivity - Date- Significance - see the AACODS checklist below
