    Abstract
    In addition to using title keywords and subject headings for searching in the online catalog, the searcher may also use class numbers as access points. Library of Congress class or call numbers are particular effective in certain kinds of specific-item subject searching and serve as supplements to keywords and descriptors, improving precision and recall. Class number searching in the database can produce unique results because these numbers collect citations in ways that differ from those of keywords and descriptors

    Abstract
    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
    The principle of uniform heading underlies the rules for headings in descriptive cataloging in the American tradition. The rationale and the evolution of the principle are examined and its implications discussed in terms of the history of cataloging codes. The ideal embodied in the principle of uniform heading has been undergoing gradual modification in recent codes and considerably compromised in cataloging practice today.

    Abstract
    The purpose of the current study has been twofold: (1) to develop a valid methodology for studying indexing consistency in MARC records and, (2) to study such consistency in subject cataloging practice between non-LC libraries and the Library of Congress
