    Abstract
    Online displays of bibliographic records in call number order can serve various functions. A literature search showed no papers or books discussing this topic directly. Various displays from online catalogues available via the Internet were examined, as were displays sent to the author by colleagues. A number of the displays were uninformative to the extent that the identification of works associated with call numbers was difficult or impossible without follow-up searching of the individual bibliographic records. Other displays provided information where further searching of the database would not be required for most purposes. Displays noted ranged from displays with call numbers alone, with no bibliographic information, to records including main entry, title, statement of responsibility, place, publisher, and date. Suggestions of useful data elements to be included in displays of bibliographic records in call number order are made for the following functions: shelflisting, cataloguing, catalogue maintenance, reference, public searches, acquisition and collection development, and inventory control. Recommendations are made that the following data elements should be present in call number displays: entire call number as a sequencing element; main entry; entire title proper, and the date. Concern is expressed that the call number filing arrangement be that followed in traditional shelflists, and a suggestion is made that possible consensus on the placement of the data elements within a display be considered in the future

    Abstract
    This paper discusses the newly developed USMARC Format for Classification Data. It reviews its potential uses within an online system and its development as one of the USMARC standards for representing bibliographic and related information in machine-readable form. It provides a summary of the fields in the format, and considers the prospects for its implementation.

    Abstract
    The automation of Bucharest University Central Library involved the compilation of a dictionary of terms to facilitate postcoordinated searching in accordance with the UDC notation attached to every bibliographic record. Describes the project and demonstrates why a multilingual UDC based thesaurus is considered as ideal indexing and searching tool. The experiment, which applied to Class 8 of UDC (Linguisitcs and Literature), illustrates how all UDC tables can be successfully used to build a thesaurus and the ways in which their limitations can be overcome by a thesaurus

    Abstract
    Thesauri-structured controlled vocabularies, designed for information retrieval-are compared with classification schemes developed for the arrangement of library materials and/or bibliographic records. The syndetic structure (BTs and NTs) within the alphabetic sequence of thesauri constitutes a hidden classification, but many thesauri include an explicit hierarchical display; some feature notation. The various structures and applications of thesauri are surveyed, with an emphasis on their increasing role in electronic information retrieval. The skills required for thesaurus construction are similar to those for the development of classification schemes. The distinction between these activities is expected to blur in the future.

    Abstract
    Potential uses for classification data in machine readable form and reasons for the development of a standard, the USMARC Format for Classification Data, which allows for classification data to interact with other USMARC bibliographic and authority data are discussed. The development, structure, content, and use of the standard is reviewed with implementation decisions for the Library of Congress Classification scheme noted. The author examines the implementation of USMARC classification at LC, the conversion of the schedules, and the functionality of the software being used. Problems in the effort are explored, and enhancements desired for the online classification system are considered.

    Abstract
    Librarians are often so eager to adopt new technologies and systems that they can lose sight of the realities that must be dealt with. Among factors that may delay use of Dewey Decimal Classification (DDC) for on-line catalogues retrieval are: limited use of DDC in libraries with operational on-line catalogues; limitations to the MARC bibliographic formats: lack of an authority structure for classification number for items catalogued. Factors that may delay development of effective classification retrieval mechanisms include unclear terminology and unreasonably high (or low) expectations.

    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
    Once the library has been through a process of transition from traditional library procedures to automated ones, natural language searching became a necessity for both indexers and searchers. Therefore, aside from the precoordinated classified catalogue we started to build a dictionary of terms in order to make postcoordinate search possible in keeping with the UDC notations assigned to each bibliographic record. After a while we came to the conclusion that the dictionary needed a control of its terms so that synonymous concepts and semantic ambuguities be avoided. The project presented in this paper shows how reality imposed the improvement of the quality of indexing and hence of the searching possibilities. Is also shows the reasons why we consider a multilingual thesaurus based on UDC an ideal indexing and searching device. The experiment applied on class 8 of UDC illustrates the way the UDC tables can be quite successfully used in building a thesaurus due to their qulities and how their limitations can be overcome by a thesaurus. An appendix to the paper contains a sample of the multilingual thesaurus given in both alphabetical and systematic layouts

    Abstract
    This paper examines issues relating to the use of the Dewey Decimal Classification (DDC) in a future development of view-based searching to Online Public Access Catalogues (OPAC). View-based searching systems, exercising the principles of fully faceted classification techniques for both bibliographic and corporate database retrieval applications, are now being applied to utilise Dewey concept hierarchies in a University OPAC. Issues of efficiency and effectiveness in the evolving organisation and classification of information within libraries are examined to explain why fully faceted classification schemes have yet to realise their full potential in libraries. The key to their application in OPACs lies in the use of faceted classification as pre-coordinated indexing and abandoning the single dimension relative ordering of books on shelves. The need to maintain a single relative physical position on a bookshelf is the major source of complexity in classification. Extensive latent benefits will be realised when systematic subject arrangements, providing alternative views onto OPACs, are coupled to view-based browser and search techniques. Time and effort will be saved, and effectiveness increased, as rapid access is provided to the most appropriate information to satisfy the needs of the user. A future for Dewey Classification divorced from its decimal notation is anticipated
