- Abstract
- It will not be an easy task to automate the Library of Congress Classification schedules because it is a very large system and also because it developed long before automation. The designers were creating a system for shelving books effiently and had not even imagined the constraints imposed by automation. A number of problems and possible solutions are discussed. The MARC format proposed for classification has some serious problems which are identified

- Abstract
- The first studies of online catalog use demonstrated that the problems of too many and too few retrievals plagued the earliest online catalog users. Despite 15 years of system development, implementation, and evaluation, these problems still adversely affect the subject searches of today's online catalog users. In fact, the large-retrievals problem has grown more acute due to the growth of online catalog databases. This paper explores the use of library classifications for consolidating and summarizing high-posted subject searches and for handling subject searches that result in no or too few retrievals. Findings are presented in the form of generalization about retrievals and library classifications, needed improvements to classification terminology, and suggestions for improved functionality to facilitate the display of retrieved titles in online catalogs

- 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
- 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
- The interfaculty centre of Bologna University began 2 years ago a project to 'translate' UDC codes into a user friendly thesaurus, with the object of creating an accurate, easy to use tool for online researches, especially those relating to periodical titles. The UDC numerical codes have been linked by a method based on synonyms to a series of corresponding verbal indices which express in natural language the concepts expressed by the codes. Thus researchers can retrieve information not only through UDC codes but also through their analogous verbal descriptors. Describes the progress of the UDC project so far, and some problems encountered

- 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
- The application of classification schemes and thesauri to improve online information retrieval can be traced back to the beginnings of online searching itself, but the true potential for using knowledge structures in the user interface has yet to be realized. View-based searching seeks to exploit the classified arrangements in thesauri and existing classification schemes to improve the performance of such systems. HIBROWSE for EMBASE is a system which demonstrates the power of applying an approach to information retrieval which is strongly related to faceted classification. It does this by employing a point a click user interface with mutually constraining views utilising knowledge structure hierarchies for both query specification and the presentation of results. The relevance of this approach to library OPACs is discussed in the context of the digital library, concluding that out legacy of research in classification and indexing is more relevant than ever in the design of systems to cope with the problems of information access

- Abstract
- This response to the paper by Dr. Chan, while accepting the merits of call number searching in the theoretical sense, raises questions about its usefulness in typical library situations. Compares searching on-line with call numbers and the use of classified catalogues and shelflists. Asks who is expected to do call number searching. Considers the availability of indexes to the classification scheme, problems created by the provision of only 1 class number per document, and the use of multiple cutter numbers to express the subject of a document.

- Abstract
- There is every indication that classification systems which are international in their use, and free from the impact of national languages, will be given strong consideration as the choice for an information retrieval language in an automated environment. The aims of the Symposium were: to provide a forum for discussion of the problems and opportunities emerging from MARC records; to reconsider intellectual level as a significant determinant of information retrieval; and to explore the potential of the Dewey Decimal Classification and the Library of Congress Classification systems as information retrieval languages in an on-line environment.
