    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
    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

    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.
