Cochrane, Pauline A. Kirtland, Monika Annotated Bibliographies Indexes Indexing Information Retrieval Library Catalogs Subject Index Terms A comprehensive guide to the literature published between World War II and 1979 which critically evaluates the Library of Congress list of Subject Headings (LCSH), this bibliography has been prepared for information personnel involved with subject authority files, thesauri, or vocabulary control. A brief bibliometric analysis of the literature precedes the bibliography, which contains sections devoted to general principles for the analysis of subject headings, rationalizations of the LCSH system, and criticism of LCSH with respect to specificity of indexing language, consistency of syndetic structure, the formation of headings, spareness of headings, and ease of use. Each section of the bibliography is accompanied by a descriptive summary of the items contained therein. Also included is an essay on vocabulary control in LCSH in which the introductions to the first eight editions of LCSH are compared. A bibliography, footnotes, two tables (a catalog of LCSH weaknesses and a chronological and topical overview of literature on LCSH), and three appendices (one an author index) are provided. Footnotes, a table comparing the introductions over the years, and reproductions of the introductions to editions 2-3 of the ALA List of Subject Headings and editions 2-7 and 9 of LCSH accompany the essay.
