    Abstract
    In 1994 Munich public libraries introduced online cataloguing and chose to test the use of RSWK draft for music cataloguing. All parts of a subject heading chain proved to have equal weight and to be retrievable separately. Some aspects were not covered, so the draft must be discussed further

    Abstract
    Derivative bibliographic relationships are the primary relationships that exist among the members of a bibliographic family--the set of interrelated works where the relationships among entities express shared semantic or linguistic activity. Derivative bibliographic relationships exist between any new conception of a work and its original source (the progenitor), or its successor, or both. Discipline was a poor predictor of derivative relationships in prior studies of derivative bibliographic relationships. For the present study random samples of works were drawn from the catalogs of the Bobst Library, New York University, and the Burke Library, Union Theological Seminary, New York. Two sites were chosen to allow a test of the differences in collection development patterns between a university research library and a theological library. Bibliographic families were compiled for each work. Results indicate: 1) derivative bibliographic relationships exist for somewhere between one-half and two-thirds of theological works in this study; 2) there is little difference in proportions of derivative bibliographic relationships or in the size of bibliographic families between the two collections; 3) there is a positive correlation between the age of the progenitor work and the size of the bibliographic family); 4) there are significant gaps in coverage of theological bibliographic families online; 5) there is some evidence of differing patterns of derivation between Judaic and Islamic literature and Christian literature; 5) forms and genres are useful in a limited way for predicting the incidence of derivative relationships in theological literature

    Includes changes to all examples throughout the publication, as approved by MARBI in January 1993. Makes obsolete the second indicator position (non-filing characters) in all of the heading fields except the 130, which is uniform titles. Also new to this edition: definition of 18X heading fields for general, geographic and chronological subdivision headings, plus related 48X and 58X fields... 7XX fields for heading-linking entries... and the control field 003, named the 'control number identifier.' Also eliminates the national-level requirement codes at the field level

    Abstract
    Recent papers have called attention to discrepancies in the assignment of LCSH. While philosophical arguments can be made that subject analysis, if not a logical impossibility, at least is point-of-view dependent, subject headings continue to be assigned and continue to be useful. The hypothesis advanced in the present project is that to a considerable degree there is a clear-cut right and wrong to LCSH subject heading assignment. To test the hypothesis, it was postulated that the assignment of a subject heading is correct if it is supported by textual warrant (at least 20% of the book being cataloged is on the topic) and is constructed in accordance with the LoC Subject Cataloging Manual: Subject Headings. A sample of 100 books on scientific subjects was used to test the hypothesis

    Abstract
    An analysis of a sample of 9.442 headings assigned by the LoC to bibliographic records disclosed 2 types of invalid headings: those that were erroneous and those that were obsolete. Each type revealed recurring patterns. Errors and obsolete elements occuring in assigned heading involve MARC coding, terminology in main headings and subdivisions, application of subdivisions, and in mechanical elements such as punctuation and capitalization. Different headings (e.g. personal name, corporate name, topical, etc.) display different patterns as well as predominance of errors and obsoleteness. Although the overall error rate is low, an awareness and understanding of patterns of errors and obsolescnce in subject heading strings should contribute to improvement in subject heading assignment and subject authority control

    Abstract
    Discusses the theory and practice of subject headings, the principle and application of subject heading lists in various countries, and the present situation of the Chinese subject heading list in Taiwan. Suggests improvements to the chinese Subject Headings as follows: to increase the number of subject headings; to control the vocabulary to be used; to use fixed fields of Chinese MARC, performing the partial function of subdivision in the chinese Subject Headings; to announce the addition, correction and deletion of subject headings regularly and to compile a users' manual; to establish a national subject heading authority file in the MARC format; and to use the Chinese Subject Headings to organize Internet resources

    Abstract
    Recognises the limitations of the existing files of Library of Congress name and subject authority records for indirect geographic subdivision. Makes recommendations for enhancements to existing authority records, which would enable online systems to assist in subject heading formulation and verify, with limited assistance by human intermediaries, whether geographic subdivision is authorized for use with a particular main heading and whether the correct form of indirect geographic subdivision is authorized for use with a particular main heading and whether the correct form of indirect geographic subdivision is given. A study of subdivided subject headings in a large bibliographic data base forms the basis of the recommendations

    Abstract
    The GRIS subject heading scheme is the outcome of a collaborative project of Italian research and academic libraries. Describes the efforts to introduce the scheme to a number of libraries in the Siena Library Service in Italy in the last 3 years. Notes the phases of this project, pricipally a series of trainign seminars and a year of experimentation, before agreement by most of the libraries to implement the scheme. Describes the main features of the electronic subject heading files as they now exist, as they cope with pre existing schemes and the new scheme. Provides statistical sata on these files and outlines the problems which remain to be solved in thre implementation of the scheme

    Abstract
    This paper recognizes the limitations of the existing file of Library of Congress authority records for subject heading assignment and validation. It makes recommendations for a new machine-readable file of authority records for topical subdivisions and for enhancements to the existing subject authority file. The recommended changes qould enable online systems to assist in subject heading formulation and verify, with limited assistance by human intermediaries, the individual components of subdivided headings. A study of subdivided subject headings in a large bibliographic database forms the basis of the recommendations

    Abstract
    In the past, there has seemed to be a stubbornness on the part of the Library of Congress to update ethnic and racial, as well as sexual and medical subject headings. Delaying change can frustrate users of today's online and card catalogues. Reviews changes that have occured over the last 20 years and shows how library catalogues can be updated, or at least rendered more useful. Shows how automation can enhance, as well as prevent, subject heading updating
