The availability of appropriate software for library applications is a continuing problem, and this directory is designed to reduce the frustration of librarians in their search for library software for a microcomputer by providing profiles of software packages designed specifically for libraries. Each profile describes the purpose of the program, microcomputer operating systems and other software and the hardware required to operate it properly, vendor address, and price. The information was gathered from questionnaires sent to each producer/broker of library software. In response to the questionnaire, many suppliers provided demonstration disks, user manuals, price lists, and other system documentation. The software profile sheets are based on the written information provided and telephone interviews with most of the firms offering library software. The software profiles are arranged alphabetically and indexes provide access to the profiles by software title, subject area, and type of microcomputer. Firms which could not be located and had no forwarding address on file with the post office are listed at the end of the directory. The software listed includes programs for audiovisual catalogs and scheduling; acquisitions control; bibliography creation; catalog card and label production; cataloging; circulation control/overdues; computer-aided instruction; database searching; creation of custom databases; online catalogs; retrospective conversion of bibliographic records; serials control; statistics; and utilities.
