Data processing was introduced to public libraries in Hawaii in 1973 with a feasibility study which outlined the candidate areas for automation. Since then, the Office of Library Services has automated the order procedures for one of the largest book processing centers for public libraries in the country; created one of the first COM (computer-output-microfilm) catalogs to be produced; converted the manual catalog to machine readable form including records which go back to the beginning of the public library system; and undertaken the installation of an online circulation system. This paper reviews the major accomplishments and presents plans for the future in each of the following areas: acquisitions, catalog, serials, circulation, Hawaiiana, nonbook materials, management information systems, reference, computer literacy, library for the blind and physically handicapped, and office management. Related flowcharts, implementation schedules, and circulation statistics are included. (THC)
