The promotion of library services in European countries requires co-ordinated use of new technologies and co-operation. To implement this the European Commission has devised a plan of action for libraries. This plan and questions relating to the use of new technologies in libraries were presented at this European conference. In all, some 42 papers covered such topics as new technologies and data collecting for preservation, networking between publishers, distributors and libraries, data and access, co-operative library systems and more. To give a world perspective, a video-conference enabled ten European, American and Japanese librarians to exchange their views and experience on the impact of new technologies on libraries in their countries - these discussions are also included.
