    Abstract
    State of the art review of the criteria used to judge and evaluate the quality of databases, including: content, ease of use, accessibility, customer support, documentation, and value to cost ratio. Concludes that the principle factor governing quality is content, defined by the scope and the coverage of the database and its currency, accuracy, consistency and completeness. Scope is determined by its composition and coverage, including time period, number of periodicals and other primary sources, number of articles and geographic and language distribution. Currency is measured by the time lag between publication of the primary source and availability of the corresponding records in the database. Accuracy is governed by the extent to which the records are free from errors of all types. Consistency depends on the extent to which records within the database follow the same rules. Completeness is measured by the consistency with which applicable data elements are assigned to all the records in the database. Reviews the major contributions to the literature in the field and summarizes the background of milestone studies

    Abstract
    Recognition, by libraries, of the need for improved efficiency and reliability in subject authority control in catalogues led to a study of the feasibility of automatically creating a subject heading validation file by scanning the OLUC. The premises were: that although the file would not be axhaustive, it would contain the majority of frequently used headings; and that the predicted level of accurary in the file would be high. A sample file of Library of Congress assigned subject headings, from the OCLC Subject Headings Corrections database was analyzed. Results showed that: the frequency of use varies inversely with the number of headings at a given rrate of use; a small number of headings with high frequencies of use accounts for the majority of total use, while a large proportion shows very low frequency of use; topical headings account for 2/3 of assigned headings; and error and obsolescence rates are both low and are in inverse relationship to the frequency of heading use. Concludes that an automatically generated subject heading validation file is feasible and could serve various purposes, including: verification of subject heading strings constructed by cataloguers; updating of subject headings in catalogue maintenance; and validation of subject headings during retrospective catalogue conversion

    Abstract
    Subject headings do not always adequately express the subject content of books and other library materials. Whether due to cataloguer error or inadequacy in the authority list, this deficiency makes it difficult for users to access information. In an attempt to solve this problem, the study evaluated the adequacy of the LoC Subject Headings assigned to the 23 books of Pierre Bourdieu, whose philosophical ideas were judged likely to form a good test of the ability of the subject headings to reflect the ideas proposed by the author. The study examined the subject headings given to 22 books, and their translations into English, Spanish, Portuguese, and German, comprising 88 records in OCLC as of Dec 91. It was found that most of the books received headings not corresponding to their content, as the headings were assigned from the functionalist paradigm. In general, LCSHs ignore the conceptual categories of other paradigms, do not match the current vocabulary used by social scientists, and are ideologically biased

    Abstract
    Authority records were compared for established headings that are identical in LCSH (18th ed.) and Moving Image Materials (MIM). The Use For, Broader Term, Narrower Term, and Related Term references in the LCSH authority file were compared with their counterparts in MIM, to determine the proportion of duplication existing between them. Fewer that 10% of these reference headings are identical. A qualitative comparison was made of the 'semantic spaces' inhibited by identical headings in different contexts: a general purpose subject access list is compared with a medium specific form and genre access list. It was found that, in many cases, headings that are identical as character strings have markedly differnt meanings in different contexts. The conclusion offered is that, both quantitatively and qualitatively, pairs of identical headings differ sufficiently from each other that the creation of authority records for each usage represents no duplication in any meaningful sense. The striking divergence, in many instances, between semantic spaces poses intellectual questions regarding the differences between the meaning of subjects and of forms and genres

    Abstract
    A thourough understanding of current subject cataloging practice, especially Library of Congress practice, will assist librarians in making the best use of new and emerging technology to ease the task of constructing subject headings. To gain insight into the most current subject cataloging practices at the Library of Congress, a random sample of one thousand bibliographic records with one or more 6XX fields and Library of Congress card numbers assigned from 1988 to the present was drawn from the BOOKSM database. Library of Congress catalogers rely heavily on the system of free-floating subdivisions in the process of constructing subject headings. Attempts to improve the subject cataloging process must take into account this fundamental characteristic of the Library of Congress subject headings system

    Abstract
    In this article the evolution of LCSH concerning women from LCSH 8(1975) through LCSH 14(1991) is traced. Dramatic changes have taken place, including an explosion of occupational headings for women, the disappearance of sexist headings and cross-references, and a shift from a somewhat narrow and condescending view of women to a more balanced view that takes into account the variety of roles they play. However, subtler forms of gender bias remain in the headings and in the ways they are applied. The author enumerates these problem areas and suggests possible solutions, concluding with a discussion of the larger issues involved in attempts to root out bias in the catalog

    Abstract
    Gives a general description of USMARC records for authority files with more detailed information on the fields used in subject headings authority files. The most important record types are explained with the use of appropriate examples. The maintenance of a subject headings vocabulary in authority file and the development of a headings language. In Poland there is no authority file maintained by the national bibliographic centre. Libraries using VTLS software have cooperated in the development of KABA, a common subject heading authority file located on the Warsaw University Library computer system
