- Abstract
- System design options and user searching options are discussed. The problems of electronic union catalogs, including a 'virtual union catalog' in particular are considered and enhancements made possible through classification are explored. The combined system of subject headings and classification is presented as the model of the integrated subject searching tool which will meet individualized learning styles and user responsive vocabulary

- 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
- The universal classification schemes developed in the 19th century are a direct response to the social changes of that era. However, the increasing use of automation in libraries has highlighted the need fir greater precision in hierarchical structures. A thesaurus of used and related headings can be employed to show the spatial relationship of semantic terms. The resulting search profile can be further enhanced by the addition of citation weighting. To assist users to define searches more accurately libraries using large general classification schemes should consider adding supplementary classification data to records

- Abstract
- The last several years have seen the evolution of prototype systems exploiting the use of the Dewey Decimal Classification (DDC) as an interface to online catalogs. One such system, calles DORS (Dewy Online Retrieval System) was developed at the University of California, Los Angeles by the authors. The feature distinguishing this system is an automatically generated chain index, in particular the algorithms that were created for its automatic generation and the problems that were encountered. The problems were of three kinds: those that were overcome, but were not for lack of time and resources and those that we believe cannot be overcome. The paper concludes with suggestions for future resaerch and possible formatting changes to the DDC feature headings that would facilitate chain-index generation

- Abstract
- With the development during the last few years of the USMARC Format for Classification Data, the potential for improving call number browsing in online catalogs has increased dramatically. For example, it is now possible to create various types of indexes to classification numbers in the online catalog. Two types of possible indexes, a chain index and an index using Library of Congress subject headings as an index to the Library of Congress classification are discussed and examples given in appendices. It is also noted that these two indexes are only two of various forms an online index to classification numbers could take.

- Abstract
- A new design for the DDC allows for display of the schedules and indexes in a hypertextual browser which was originally designed for the more conventional thesaurus with BT-NT, RT and USE-UF relations. Features of the DDC which approxumate those relations and the presentation of the rich vocabulary found in the hierarchical structure, captions, index entries and notes are represented for the library user's perusal and choice before searching a library's holdings. By dragging and dropping parts from such a display into a search window, the search for bibliographic items can begin and revised painlessly. Information such as class numbers of subject headings for retrieved items can be dragged and dropped into the searchw indow of the Visual Dewey display window as it suits the user to review vocabulary or revise the search results. This seamless to-ing and fro-ing allows for a truly interactive and spontaneous search environment, with maximum assistance at point of need. 'File folders' exist for saving any Visual Dewey information, any retrieved items, etc.

- Abstract
- Editors of long-standing classifications have to adopt their schemes to totally different circumstances from those they were originally designed to suit. The need to retrieve information accurately in an online environment and a world dominated by the Internet is vital and contrasts with the basic linear approach for which these classifications were intended. The latter need still has to be satisfied, so ways of achieving both goals must be explored. The need for greater synthesis, clearly defined factes, with distinctive notation and a closely adhered to citation order is essential. An expressive notation is attractive in an online environmen. Modern educational approaches make traditional structures meaningless and the current economic climate and expense of developing new publication formats is reducing revision budgets. Co-operation between editors and the use of one scheme, e.g. DDC, as a switching language between other schemes, e.g., UDC, thesauri and subject headings lists are one way forward. Existing co-operative projects and future plans between the editors of DDC, UDC and BC2 are discussed and the complementing of classification by a thesaurus is recommended
