Grey Literature - Definition

Approved at the Third International Conference on Grey Literature in 1997, 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". At the Sixth Conference in 2004, a postscript was added: grey literature is "...not controlled by commercial publishers, i.e., where publishing is not the primary activity of the producing body". -- Schopfel, J., and Farace, D.J., 2010. "Grey Literature" in Bates, M.J. and Maack, M.N. Encyclopedia of Library and Information Sciences (3rd ed.)
