GreySource provides examples of grey literature to the average net-user and in so doing profiles organizations responsible for its production and/or processing. Only web-based resources that explicitly refer to the term grey literature (or its equivalent in any language) are listed. 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. 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. info@greynet.org
