Papers delivered at the 1989 program session of the Library of Congress Network Advisory Committee (NAC) focused on ways in which newer technologies and document delivery networks are changing current practices in document delivery and information services. Charles P. Bourne, chair of the program committee, presented an overview of document delivery services and the impact of technology on the growth of these services in his paper, "A Review of Technology and Trends in Document Delivery Services." This was followed by seven papers focusing on various aspects of document delivery service: (1) "Interlibrary Loan: Current Use and Patterns" (Kate Nevins, OCLC); (2) "DOCLINE (an automated document requesting and routine system): The National Library of Medicine Experience" (Lois Ann Colaianni); (3) "Document Delivery Systems at the University of California: An Overview" (Dennis E. Smith and Clifford A. Lynch); (4) "Application of Technology in Document Delivery: The CISTI (Canada Institute for Scientific and Technical Information) Experience" (Margaret Y. Walshe); (5) "Information on Demand: Information Broker Services--The IOD (Information on Demand) Experience" (Christine Maxwell); (6) "UMI/IEEE Products" (Pauline Angione Zoellick); and (7) "Image Transmission over Internet: The NAL (National Agricultural Library) Experience" (Gary K. McCone). This report includes the text of the eight papers, a summary of the business session, and five appendices: the meeting agenda; a statement by James H. Billington, the Librarian of Congress; Network Advisory Committee (NAC) criteria for membership; letters to Daniel H. Carter by Henriette D. Avram and George F. J. Mesmer; and the 1989 report of the U.S. National Commission on Libraries and Information and Information Science. (DB)
