    Abstract
    Description of an attempt to improve OPAC subject access at Kobe University Library using Nippon Decimal Classification, 8th ed. (NDC8). Examines the theoretical aspects of using a classification for subject searching, then explains the Kobe system. Using the NDC8 machine-readable data file, a database was created for the OPAC, incorporating class numbers and subject headings. Difficulties arise from subdivisions and the structure of NDC8 itself, but it is an important area for development

    Abstract
    In 1991 60,4% of Japanese university libraries had introduced computerized systems and 57,5% of these had computerized catalogues. In this context, discusses the following: subject searching in computerized catalogues; standardisation of OPACs, particularly as these are now available to a wide range of external users; and access to journal articles, especially in view of increasing journal purchase relative to books
