    Abstract
    The Library of Congress Classification (LCC), originally designed for classifying the Library's own collection, is now used in a wide range of libraries, both in the United States and abroad. This entry recounts its history and development from its genesis to the present time, leading up to an explanation of LCC structure, tables, and notation. It then considers the system's potential for wider application in the online age, through speculation on using LCC as a tool for (a) partitioning large files; (b) generating domain-specific taxonomies; and (c) integrating classification and controlled subject terms for improved retrieval in the online public access catalog (OPAC) and the Internet. Finally, analyzing both its strong and relatively weak features, it addresses the question of whether in its current state LCC is in all respects ready for playing such roles

    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
    Recent trends, driven to a large extent by the rapid proliferation of digital resources, are forcing changes in bibliographic control to make it easier to use, understand, and apply subject data. Subject headings are no exception. The enormous volume and rapid growth of digital libraries and repositories and the emergence of numerous metadata schemes have spurred a reexamination of the way subject data are to be provided for such resources efficiently and effectively. To address this need, OCLC in cooperation with the Library of Congress, has taken a new approach, called FAST (Faceted Application of Subject Terminology). FAST headings are based on the existing vocabulary in Library of Congress Subject Headings (LCSH), but are applied with a simpler syntax than required by Library of Congress application policies. Adapting the LCSH vocabulary in a simplified faceted syntax retains the rich vocabulary of LCSH while making it easier to understand, control, apply, and use.

    Contribution to a thematic issue devoted to a subject control in on-line catalogues. Examines whether a subject cataloguing code is, at this point in time, necessary or economically feasible, as well as questioning who will develop such a code and if experiences with AACR2 should make librarians fearful or hopeful about similar work with subject headings.

    Abstract
    An informal survey was conducted for the purpose of identifying instructional materials used in teaching cataloging and classification in library and information science programs in the United States and Canada. Based on responses from instructors in these areas, three groups of instructional materials were identified: cataloging and classification tools, textbooks, and background and supplementary reading materials.

    Abstract
    This entry discusses the importance of semantic interoperability in the networked environment, introduces various approaches contributing to semantic interoperability, and summarizes different methodologies used in current projects that are focused on achieving semantic interoperability. It is intended to inform readers about the fundamentals and mechanisms that have been experimented with, or implemented, that strive to ensure and achieve semantic interoperability in the current networked environment.

    Abstract
    Introduction to the methods of classifying and arranging library collections according to the DDC. It begins with a brief history of the DDC, followed by discussions, the methods of analyzing the subject content of documents to be classed, and the proper procedures of assigning class number. Its essential aims is to explain the proper methods of applying the DDC schedules, of locating and assigning the appropriate class number, and of synthesizing a class number if need be. Examples and exercises are based on ed. 20

    Abstract
    This article describes FAST, the Faceted Application of Subject Terminology, a project at OCLC to make Library of Congress Subject Headings easier to use in Dublin Core metadata by breaking out facets of space, time, and form. Work on FAST can be watched at its web site, http://www.miskatonic.org/library/, which has recent presentations and reports. It is interesting to see facets and Dublin Core combined, though both LCSH and FAST subject headings are beyond what most people making a small faceted classification would want or need.

    Abstract
    After an introduction that addresses the means people use to search for information, this entry articulates the principles underlying various subject access options, including both controlled vocabulary systems and classification. It begins with a brief history of subject access provisions, including an account of the impact of automation, and goes on to discuss in some detail the principles underlying American library practice in respect to subject access. It then, briefly, describes selected subject-access schemes (including both subject heading lists and classification systems) in terms of how they reflect the principles presented, and how well they fulfill their stated functions.
