    Abstract
    The derivation of a thesaurus from a new schedule for UDC class 61 Medical Sciences which has been restructured into a faceted classification system using the framework provided by the Bliss Bibliographic Classification. The resulting thesaurus is intended to serve as a tool for indexing and searching but will also be the index to the 61 class itself. The background for the research is briefly described. The sources and methods used to select the descriptors and define their relationships are discussed. Problems are identified and some solutions proposed

    Abstract
    The latest thesaurus guidelines, ISO 2788 and ANSI/NISO Z39.19-1993, were published before many recent changes in the nature of databases, and before the full impact of the Internet on information storage and retrieval. The major changes are addressed in light of implications for reconsideration and possible revision of the guidelines
