This inventory provides profiles, tables, and listings describing automated library activities at 103 Association of Research Libraries (ARL) institutions. The inventory includes analyses of aggregate information from individual library profiles which are then divided into three categories that reflect primarily bibliographic functions: (1) technical services (acquisitions, fund accounting, authority control, cataloging/local, cataloging/utility, serials receipt control, data conversion); (2) public services (interlibrary loan, online searching, CD-ROM, online catalogs, circulation, reserve, materials booking, document delivery, public computing); and (3) office automation (electronic mail, report generation, financial reporting). The individual library profiles present information on the operating status of automated functions, number of stations, scope, and access, and vendors for the selected functions. A copy of the survey instrument, which includes a descriptive factors list and a listing of functions, is appended. (MAB)
