"Grey literature may also be defined as the type of documents written and published for a very limited niche audience, certainly outside of all major distribution channels and often difficult to find in the most commonly-consulted bibliographic databases. This literature is expanding exponentially and may include presentations at conferences, health technology assessments done by hospitals, and certain government documents. In 2013, there is a lack of unanimity on the definition of grey literature, as its boundaries continually shift and evolve as new technical means are developed." HLWiki Canada
