- 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
- 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
- 2 concepts of facets have been used in studies of classification systems: one for systems which take hierarchical structure and the other for systems which take multidimensional structure. Both correspond to 'principles of division'. The concepts of facets in multidimensional structure systems is used for addressing a subject from many aspects so should equate to the broadest principle of division in order to grasp a multiplicity of aspects. The concept of facets used in hierarchical systems addresses only the significance of a coherent set of items. This concept is not distinguished from the principle of division and there is no purpose in introducing a concept of facets into hierarchical systems in addition to the principle of division

- 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
- 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
- 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
- Considers classification systems from a structural point of view. Distinguishes between 2 kinds of methods of categorization of classification systems: the first categorized by structure, either hierarchical or multidimensional; and the second by style of expression, either enumerative or sythetic. Identifies 4 leading classification systems according to their structures: DDC, LCC, UDC and Colon Classification. Focuses on DDC referring to 2 interpretatives of its structure, one of which is hierarchical and the other is partially multidimensional. Also relates this to the matter of interpretation of the notation '0', interpreted in one instance as 'generalities', and in another as 'coordination sign'
