Key Topics
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). http://www.nyam.org/library/greylit/whatis.shtml
By virtue of the definition above, it is obvious that grey literature encompasses a lot of different types of materials and publications and is generally not going to be found through standard indexing sources. Other definitions are listed below but they all pretty much concur that grey literature is difficult to confirm and locate.
When searching for grey literature it is often best to try the originating
source first and then look for organizations that might have started to build
indexes or databases of such information. A number of technical report and periodical
literature databases covering a variety of topics are listed.

Grey Literature is "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 moves the field of grey literature beyond established borders into new frontiers, where lines of demarcation between conventional/non-conventional and published/unpublished literature cease to obstruct further development and expansion. At the same time, this new definition challenges commercial publishers to rethink their position on grey literature."
Gray Information Functional Plan. The Interagency Gray Literature Working Group. Foreign Broadcast Information Service, Executive Agent. APPENDIX A: GLOSSARY
Gray information/literature - foreign or domestic open source material that usually is available though specialized channels and may not enter normal channels or systems of publication, distribution, bibliographic control, or acquisition by booksellers or subscription agents. Gray literature, regardless of media, can include, but is not limited to, research, technical, and economic trip reports, working papers, discussion papers, unofficial government documents, proceedings, preprints, research reports, studies, dissertations and theses, trade literature, market surveys, and newsletters. This material cuts across scientific, political, socioeconomic, and military disciplines. Organizations that typically generate the largest quantities of gray literature include: research establishments (laboratories and institutes), national governments, private publishers (pressure groups/political parties), corporations, trade associations/unions, think tanks, and academia. A document with an ISBN number may still be classified as gray literature.
