What is Grey Literature?
Grey literature is defined as ‘that which is produced on all levels of government, academics, business and industry in print and electronic formats, but which is not controlled by commercial publishers.’ Examples include technical reports from governmental, inter-governmental and non-governmental agencies or research groups, working papers from research groups or preprints, thesis/dissertations and conference papers.
