Abstract

Library of Congress Subject Headings (LSCH), which celebrated its 100th birthday in 1998, is the largest cataloging and indexing language in the world for the indication of the topics and formats of books and similar publications. It consists of a controlled list of main headings, many with subdivisions, with a rich system of cross references. It is supported by the U.S. government, and undergoes systematic revision. In recent decades its managers have begun to confront challenges such as biased terminology, complicated syntax (how terms are put together to form headings), and effective displays in electronic media. Many suggestions have been made for its improvement, including moving to a fully faceted system.

Abstract

Moving to a fully faceted syntax would resolve three problems facing Library of Congress Subject Headings (LCSH): 1. Inconsistent syntax rules; 2. Inability to create headings that are coextensive with the topic of a work; and 3. Lack of effective displays for long lists of subdivisions under a single subject heading in OPACs and similar electronic displays. The authors advocate a fully faceted syntax using the facets of a modern faceted library classification (The Bliss Bibliographic Classification, 2d ed.). They demonstrate how this might be accomplished so as to integrate the new syntax with existing headings.

Abstract

File display-the way in which catalog records are arranged for display-is a principal determinant of access to printed library catalogs, whether they be on cards, on microform, or in book form. In 1980, both the American Library Association and the Library of Congress published new sets of filing rules which represent significant departures from traditional library catalog arrangement in North America. These new rules are analyzed and compared with each other and with their predecessors, the 1956 LC and the 1968 ALA filing rules, on the basis of fundamental attributes of files and filing: (1) the symbols considered in arranging records together with the filing values assigned to them, and (2) the underlying basis of filing-symbols or concepts. Numerous examples of the very different sequences which result in the application of these codes are provided and discussed. The purpose of this paper is to help clarify filing options and thereby to help librarians make more informed choices for the display of their own catalog files.
