What is Grey Literature?
The Fourth International Conference on Grey Literature (GL '99) in Washington, DC, in October 1999 defined grey literature as follows: "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."
In general, grey literature publications are non-conventional, fugitive, and sometimes ephemeral publications. They may include, but are not limited to the following types of materials: reports (pre-prints, preliminary progress and advanced reports, technical reports, statistical reports, memoranda, state-of-the art reports, market research reports, etc.), theses, conference proceedings, technical specifications and standards, non-commercial translations, bibliographies, technical and commercial documentation, and official documents not published commercially (primarily government reports and documents) (Alberani, 1990).

A Selection of Web-based Resources in Grey Literature. GreySource provides examples of grey literature to the average net-user and in so doing profiles organizations responsible for its production and/or processing. GreySource identifies the hyperlink directly embedded in a resource, thus allowing immediate and virtual exposure to grey literature.
The web-based resources appear within categories derived from the COSATI (American) and SIGLE (European) Classification Systems, which were recently adapted by the OpenGrey Repository. The few changes that have been introduced into the classification scheme are intended to facilitate the search and retrieval of net-users. New examples are welcome and will be indexed in GreySource. firstname.lastname@example.org
