    Abstract
    Updated version of an earlier edition which underlines, on the one hand, the growing importance of grey literature as an information source and the need for guidelines for its further exploitation and, on the other hand the many changes which are taking place, not least with respect to electronic publishing and the rise of the Internet and WWW. Individual chapters deal with specific issues, including: the nature and development of grey literature; grey literatur collections and methods of acquisition; bibliographic control; cataloguing and indexing; specialist means of distribution, microforms and the Internet; theses, translations and meetings papers; aerospace; life sciences; the European Community; education; energy; science and technology; keys to reports series codes; trade literature; and a list of useful addresses of organizations and contacts
