Based on evidence (empirical data, inquiries, case studies), this workshop will provide deep insight into the evolution of document supply from traditional print copy delivery to a modern service of resource discovery and secure electronic supply. Four topics will be presented: the changing needs of customers from the public and corporate sector, the use of new technologies in the front- and back-office by major document suppliers (The British Library, Infotrieve, FIZ Karlsruhe, INIST), resource sharing and networking on the national and international level, and the negotiation of copyright agreements with publishers (‘level playing field’). The aim of the workshop is to confront empirical findingswith the experiences, needs and opinions of the participants from the library and publisher sectors.
