    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

    Abstract
    Considers the current state of online catalogues and future directions in designing the next generation, addressing both the content and presentation of information in the catalogue. Reports on a user survey which identified the varieties of catalogue failure and users' recommendations for improvements. Suggests pragmatic solutions to problems posed by large retrieval sets and the tendencies of searchers of sophisticated systems to use only a few commands and to examine only the first few records in a large retrieval set. The chaotic and contradictory nature of the OPAC in a networked environment is characterized as 'a great disorder in an order'. Discusses paradoxes that confront both users and designers of future online catalogues
