Grey literature is information that is published non-commercially or remains unpublished. It is produced by organisations where publishing is not the primary activity, such as companies, universities, government departments and Non-Governmental Organisations (NGOs). Grey literature appears in many formats including reports, patents, posters, statistics, theses and working papers.
