COMPUTERIZED BIBLIOGRAPHIC SERVICES FOR BIOMEDICINE.

By its development of improved media for dissemination of information, the National Library of Medicine is fostering a greater awareness and a better understanding of research and development efforts in behalf of public health and clinical medicine, and a more rapid translation of research into clinical application. The library's transformation from a passive repository of information to an active ally of the researcher, teacher, and clinician has led to increased use of medical library facilities and has stimulated thinking through better communication of published information. The library's success in using automation for bibliographic control of medical literature suggests that other disciplines that have not already developed automated techniques of literature-reference retrieval might profitably do so.

DATA PROCESSING ASPECTS OF MEDLARS.

The speed and volume requirements of MEDLARS necessitate the use of high-speed data processing equipment, including paper-tape typewriters, a digital computer, and a special device for producing photo-composed output. Input to the system is of three types: variable source data, including citations from the literature and search requests; changes to such master files as the medical subject headings list and the journal record file; and operating instructions such as computer programs and procedures for machine operators. MEDLARS builds two major stores of data on magnetic tape. The Processed Citation File includes bibliographic citations in expanded form for high-quality printing at periodic intervals. The Compressed Citation File is a coded, time-sequential citation store which is used for high-speed searching against demand request input. Major design considerations include converting variable-length, alphanumeric data to mechanical form quickly and accurately; serial searching by the computer within a reasonable period of time; high-speed printing that must be of graphic quality; and efficient maintenance of various complex computer files.
