Abstract

Based partly on chapters in a forthcoming book 'Technology and Management in Library and Information Sciences' by F.W. Lancaster and B. Sandore. Some inportant functions of a research library operating largely in a networked digital environment are illustrated. The ability of artificial intelligence and expert system technologies to contribute to these functions is discussed, in the light of a report from the American Association for Artificial Intelligence, as well as experiences with these technologies in the library world and elsewhere
