Introduction to Grey Literature

Grey literature is any material published outside of book and journal publishing. This includes most webpages, government documents, theses, corporate documents, reports, conference proceedings, online handbooks and manuals, and much more. Systematic and scoping reviews often include information from clinical trial registers, theses, and conference abstracts. Health technology assessments often include information from other HTA's or systematic reviews, economic reports, government regulatory information, clinical practice guidelines, etc.
