The Southwestern Library Association (SWLA) conducted an inventory and study of the SWLA libraries in cooperative, network, and computer activities to collect data for use in planning future activities and in minimizing duplication of efforts. Questionnaires were mailed to 2,060 academic, public, and special libraries in the six SWLA states. Completed questionnaires returned by 938 libraries were encoded into a Hewlett-Packard 2000 minicomputer using a standard questionnaire analysis program to tabulate and cross-tabulate the answers. Tabulated information includes network participation, type of computer activities participation, circulation system employed, and survey summaries by state and by type of institution. The 98 library networks within the SWLA, including the member libraries and cooperative activities in which they participate, are listed. (Author/JAB)
