Three papers set the framework for a 1982 program session on document delivery organized by the Library of Congress Network Advisory Committee. Following a list of committee members, the first paper, by James L. Wood describes: (1) dimensions of document delivery activity in the United States including statistics on borrowing and lending organizations, document delivery transactions, fill rates, turnaround times, types of documents requested, and costs; (2) component parts of the current document delivery process, incorporating awareness of document existence; identification of sources for borrowing; request verification, generation, transmittal, and processing; loan or copy transmittal; fee payment; and return of originals; and (3) changes expected in the document delivery process up to 1986. A glossary and explanation of acronyms are provided. The second paper, by M. E. L. Jacob, briefly reviews the technologies affecting document delivery in terms of input, storage, communication, and output. A bibliography is supplied. The third paper, by Susan H. Crooks, sets the stage for the future of libraries in the year 2000 by creating five scenarios encompassing a printed text service without books, a national reference service provided by a public corporation, a community culture center, a college/university information service, and an institute of research libraries. The impact of technology and market developments on library services is also discussed. (ESR)
