    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.

    Abstract
    Suggests that recent developments in the way information is generated, packaged amd accessed have broadened and changed the nature and application of classification in library and information networks. Examines the role of classification by posing the following questions: what, how and why do we classify? Within this context the expanding role of classification is examined with regard to how classification affects accessing, browsing, identifying, navigating, mapping and evaluating information and how it is and may be used in collection and database management, controlled vocabulary construction and development, and research

    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
    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
