    Abstract
    As the online catalog continues to be developed and refined, the question arises as to how the traditional subject analysis tools, the LCSH, the LCC, and the DDC, can be most effectively adapted to the online environment. This article examines the limitations and potentials of these tools and the challenges of incorporating them online. The traditional and potential functions of these tools, the requirements for their becoming efficient online cataloging and retrieval tools, and recent developments toward these goals are discussed

    Abstract
    The chapter deals with methods of subject cataloguing, subject analysis and representation of library materials and outlines the practice of subject searching in library catalogs after the introduction of online catalogs. The vocabulary control methods in the Library of Congress Classification and LCSH are described and strategies for the use of theses systems in online retrieval situations are outlined

    Abstract
    Zu den großen Herausforderungen einer sinnvollen Suche im WWW gehören die riesige Menge des Verfügbaren und die Sparchbarrieren. Verfahren, die die Web-Ressourcen im Hinblick auf ein effizienteres Retrieval inhaltlich strukturieren, werden daher ebenso dringend benötigt wie Programme, die mit der Sprachvielfalt umgehen können. Im folgenden Vortrag werden wir einige Ansätze diskutieren, die zur Bewältigung der beiden Probleme derzeit unternommen werden

    Abstract
    In respect to the nature and quantity of available information, 1876 was a very different world from the one we know in the 1990s. Yet in spite of over a century of changes, the Dewey Decimal Classification (DDC), the system that helped organize a small college library, has grown to one that is helping the whole world organize its vast store of information resources. In this closing session, I would like to summarize some of the major factors that have contributed so far to the Dewey system's success as an information organization tool. I will also discuss ongoing efforts to ensure its viability in the future

    Abstract
    The Library of Congress Classification (LCC), being a system originally and specifically designed for the Library's own collection, generally eschews alternatives. Within the LCC schedules, alternatives are found occasionally in earlier editions; there are no alternative numbers in recently developed or revised schedules. On the other hand, many alternative numbers representing different treatment of specific types of materials such as bibliographies and monographic series are provided in LC MARC records. Such numbers may be used by other libraries that prefer the alternative treatment. In addition, many LC MARC records also include class or call numbers based on other classification schemes, including the Dewey Decimal Classification (DDC), the National Library of Medicine Classification (NLM), and the Superintendent of Documents Classification. The alternative class numbers assigned from other classification systems are provided as services to libraries not using the Library of Congress Classification.
