Abstract

Delineates on the changing role of vocabulary control devices such as classification, subject headings, and thesaurus. Identifies the basic issue in the design and development of these devices and their role in the changing information technology. The paper identifies the differentiations needed in the new roles of these devices in data base technology

Abstract

This work systematically examines printed and automated descriptive cataloging and subject access. Background information is presented in the opening chapters, followed by four core chapters on decriptive cataloging and subject access in both printed and automated formats. Many facets of the topic are explored, including card catalogs, bibliographies, subject headings, thesauri, MARC, OPACs, periodical and book indexes, and CD-ROM.

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

Classaurus is a faceted hierarchic scheme of terms with vocabulary control features. It is a system of terms having separate hierarchic schedules of the elementary categories: discipline, entity, property and action, together with their respective species/types, parts and special modifiers. Also there are separate schedules for the common modifiers: form, time, environment, and place. Each of the terms in these hierarchic schedules is enriched with synonyms, quasi synonyms etc. The hierarchic schedules constituting the systematic part is supplemented by ab alphabetical index of chain entries. Classaurus is used in the formulation of subject headings in general, and in particular, subject headings according to the Postulate based Permuted Subject Indexing (POPSI) language. For the construction of classaurus the POPSI language itself provides guidelines. A set or programs have been developed to construct a classaurus using as input, subject headings formulated according to POPSI language which are enriches with certain codes to deniote the different elementary categories, their species, parts, special modifiers and other common modifiers of different kinds. The resulting classaurus has hierarchic schedules but terms in an array are arranged only alphabetically. The hierarchic schedules constitute the systematic part of the classaurus. The system generates an alphabetic index part to the systematic part, in which for each term its broader terms are kept to its right hand side successively along with a code to denote the schedule to which the term belongs. To find out the position of a term in the systematic part, the whole entry for the term in the alphabetic part is taken and the sequence of the terms in it is reversed. Using the code for the schedule in the entry, the appropriate hierarchic schedule is selected. The schedule is then searched using the broader terms successively as keys until the the term in question is reached, wherein all the hierarchically related terms could be found, including synonyms, quasi-synonyms etc. Both the systematic part and the alphabetical index part are printed out for manual reference and also kept as direct access files for on-line access and on-the-spot updating and building up of the classaurus while inputting new subject headings formulated for this purpose

Abstract

Four policy proposals are made for Library of Congress subject headings affecting geographic areas: consistency of form of place names in subjects; consistency and completeness of period subdivisions under place names; automatic Ge of place names as initial elements in map subject cataloging; and abandonment of the (May Subd Geog) concept in favor or clearer and more accurate notations.

Abstract

Presents the results of research carried out to discover whether or not the ability to search an online catalogue using keywords is a reasonably alternative to a built-in cross reference structure for variant forms. MARC records were checked against LoC authorities for references from non-preferred headings. All keywords in these references were then compared, and matched, when possible, with keywords in any MARC fields

Abstract

Reviews the organisation of the work of cataloguing standardisation in France and in standards published or in preparation. French standards follow IFLA reommendations on rules for bibliographic descriptions and headings. Standardisation of formats is less developed; however MARC is gaininig ground as a national exchange format, whilst USMARC is also used by university and public libraries. French policy on cataloguing standards aims both to promote international exchange of biblio-graphic recordswhile respecting national access requirements, and to simplify cataloguing by promoting the use of medium-level bibliographic records.

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.

Abstract

J. Kaiser (1868-1927) developed a system of subject indexing based on what he called "concretes" and "processes" to govern the form of subject headings and subdivisions. Although Kaiser applied his systematic indexing to specialized technical and business collections, his ideas are entirely applicable to all book collections and catalogs. Though largely ignored, Kaiser's system is of permanent interest in the study of the development of subject analysis

Abstract

A new cataloging and information access tool for children's media is proposed, which combines the most useful aspects of library subject-headings lists and thesauri with some unique aspects, and meets for the first time the American Library Association recommen-dations for the subject cataloging of juvenile materials. Computer-based production of such a tool offers considerable economies and opportunities. A project is now under way to produce such a listing

Abstract

The principle of uniform heading underlies the rules for headings in descriptive cataloging in the American tradition. The rationale and the evolution of the principle are examined and its implications discussed in terms of the history of cataloging codes. The ideal embodied in the principle of uniform heading has been undergoing gradual modification in recent codes and considerably compromised in cataloging practice today.

Abstract

Abstract

The development and use of the MARC Archival and Manuscript Control (AMC) format is described. The format's unique characteristics stem largely from the needs of the archivl community for both a uniform means of control of materials at the collection level and a powerful tool for exchanging information about archival holdings. Uniques aspects of AMC cataloguing are described, including differing approaches to access points, form of entry, title, physical description, notes, subject headings, and call numbers.

Abstract

This paper traces the efforts made by IFLA (the International Federation of Library Associations and Institutions over the past three decades to promote the concept of Universal bibliographic Control in relation to authorities and authority control. It covers the work done by various groups within IFLA to develop standards for personal and corporate name headings, for authority and reference entries, and for UNIMARC/Authorities. The paper concludes with a summary of possible models for the future development of a systems infrastructure for international authority control.

Abstract

Results of previous catalog research indicate that users want improvements in subject searching features, noting display of terms related to their topics as especially desirable. This study reports the findings of an examination of subject searchers' use of such a feature provided through online display of authority information from Library of Congress Subject Headings for terms used in the catalog. It was found that, of the terms entered by users, 78 percent were an exact or close match to catalog terms, and another 14 percent matched "see" references. Although additional information was available for nearly half of the searches performed, it was used in only 28 percent of these cases. It is suggested that improvements in subject searching features are needed to encourage use of available syndetic structures

Abstract

An important part of cataloging education in library schools is descriptive cataloging, which is concerned with preparing the descriptions, entries and name headings for library materials. Although debate occurs over the primacy of theory and principles, or practices, and whether descriptive cataloging or subject analysis should receive the most emphasis, there is general agreement that all students need instruction in the processes of cataloging. The descriptive cataloging segment of the curriculum of the Graduate School of Library and Information Science, University of Washington, is described to illustrate one approach to cataloging education.

Abstract

Pro-Cite is a software package for managing personal bibliographic data bases from which printed bibliographies are frequently required. Condisers the kinds of project for which Pro-Cite is intended, and those for which it is not intended. In the latter category is included the management of large permanent data bases to which powerful online access is frequently required. Its strength lies in its specialisation: it provides pre-defined data structures for various kinds of printed and audiovisual output formats corresponding to a range of standard styles. Discusses the package under the following headings: editing, searching, printing and browsing, indexing, and sorting. Examnines the use of Biblio-Links which are reformatting devices used to convert downloaded on-line serch results to Pro-Cite format
