    Abstract
    The 'facet-space' approach for accessing document records organized by faceted classifications is described. The interface gives users detailed control over the facet display and it makes use of color to reduce the number of windows which need to be presented. The interface supports searching. A cluster analysis is described for organizing search return lists based on facets distances. The implementation is applied to 1381 summaries of computer science dissertations as organised by the ACM Computing Reviews classification system

    Abstract
    The patent documentation at the European Patent Office (EPO) is organized according to the 120.000 subdivisions of the EPO's internal classification scheme (ECLA). In some fields, indexing schemes such as In Computer Only codes (ICO) provide additional ways of accessing the documentation. To meet the needs of patent examiners it was decided to develop a new DOCumentation TOOL (DOCTOOL). This tool would make it possible for examiners to enter their indexing codes directly online at their workplace and would, in addition to the existing ECLA and ICO schemes, also provide the possibility to assign keywords and free text to documents

    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
    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.
