    Abstract
    The meeting comprised a free-ranging discussion of topics relating to the development and use of OPACs. The following issues which challenge OPAC systems designers were identified: increasing precision in processing large retrieval sets, the addition of tables of contents data to enhance catalogue records for periodicals; privacy matters related to the needs for user identification or authentication; and the potential of the Z39.50 standard for networked computer to computer information retrieval. The future OPAC is likely to be one building block in a larger nexus of information structures, interacting with myriad other servers on the user's behalf and providing the needed intellectual filtering to deliver meaningful results
