    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
    Discusses indexing methods for moving graphical images and suggests the use of the new indexing language, the Moving Picture Description Language (MPDL) which has the following 7 frames: subject, time, location, object, characteristics, actions, and sensibility. MPDL allows indexers to assign one or more indexing terms to each frame. The retrieval experiment used 110 video images obtained from television news indexed by MPDL and other indexing methods and revealed that MPDL was the superior method. Suggests that MPDL presents many opportunities for improving the indexing and retrieval of the moving graphical image

    Abstract
    Most of the criteria proposed to date for the evaluation of OPACs focus on evaluation of their retrieval function. Argues that the storage function is more important because the quality of information retrieval systems is dependent on the quality of stored information as well as the description and depth of indexing of stored information. States that OPACs should therefore be evaluated from the perspectives of both storage and retrieval functions. Examines 4 studies on criteria for evaluating OPACs and suggests a new evaluation framework based on the work of C.R. Hildreth

    Abstract
    A survey of Japanese OPACs available on the Internet was conducted relating to use of keywords for subject access. The findings suggest that present OPACs are not capable of storing subject-oriented information. Currently available keyword access derives from a merely title-based retrieval system. Contents data should be added to bibliographic records as an efficient way of providing subject access, and costings for this process should be estimated. Word standardisation issues must also be addressed

    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

    Abstract
    The Nippon Decimal Classification (NDC) system, extensively used in Japanese libraries, was devised in 1929. It is difficult to use NDC to classify world literature, such as fiction in English by non American, non British writers. This is not necessarily straightforward in other classification schemes but a survey of 40 Japanese university libraries, of which 24 responded, showed remarkable inconsistencies in the treatment of 22 world literature authors. NDC clearly needs updating to deal with this problem

    Abstract
    Describes a study conducted to compare the use of a new OPAC with that of the card catalogue looking primarily at the area of subject access. Library science students at a private university were asked to respond to questions concerning: the number of subject searches and searches for specific items that they carried out on the OPAC and on the card catalogue; the success rate of the catalogue searches; how the search was carried out (classification number or keywords); librarian assistance required; and knowledge of the Nippon Decimal Classification. Results revealed that while there was an increase in the number of users as a result of the introduction of OPAC facilities, there were certain aspects which required attention such as the area of subject searches

    Abstract
    Reports a survey conducted in April 1997 of 136 Japanese WWW and Telnet OPACs from the persepctive of their functions and user interfaces. These included: types of searchable files; access points; kinds of displays; login commands; search methods; Boolean operation; help functions; search history; and browsing of indexed terms. Results indicate a sharp rise in the number of WWW OPACs and problems with the provision of functions and user interfaces by Japanese WWW OPACs
