These two papers on the subjects of videodisc technology and medical library networking were presented at the 1982 International Federation of Library Associations (IFLA) conference. The first, "Videodisc Technology and Applications" by Earl Henderson (United States), examines the videodisc player and the premastering (five-function process: image capture, processing, signal encoding, assembly, and simulation) of audiovisual material to produce an interactive audiovisual videodisc with entertainment, educational, and electronic publishing applications. Also included is an overview of different videodisc systems and their mutual interchangeability. Both software development and the audiovisual production process are covered. The second, "The Medical Library Center of New York [MLCNY]: An Independent, Privately-Funded Network" by William D. Walker, describes the establishment of the center as a pioneer in biomedical information networking, and its membership structure and financing. Also described are MLCNY programs and services involving interlibrary lending; serials exchange; cooperative acquisitions and cataloging; automated serials control; and the production of union lists of medical serials, monographs, and nonprint items. The paper concludes with a discussion of the reason for MLCNY's success. (ESR)
