This paper traces the development of classification at the Library of Congress in terms of its broader context and by accounting for changes in the present system since its initial period of creation between 1898 and 1910 and the present. Topics covered include: (1) Early Growth of the Collections; (2) Subject Access During the Early Years; (3) A.…

Describes the substantial changes in existing catalog formats, products, and the National Bibliography entailed in the British Library's commitment to AACR2 and Dewey 19. The conversion involved not only headings but an algorithmic conversion of the descriptive cataloging. Included are the impact on services, retrospective conversion, and common…

Recommends an expansion of MARC codes for decimal class numbers to enhance automated subject retrieval. Five values for a second indicator and two new subfields are suggested for encoding hierarchical relationships among decimal class numbers. Additional subfields are suggested to enhance retrieval through analysis of synthesized numbers in…

Presents overview of library classification and automation (1940-84), including use of Dewey Decimal and Library of Congress classification in online cataloging systems. Highlights include classification number access in existing online catalogs, functions of classification records, specifications for authority file records, and the nature of…

Discusses cataloging policy at the University of Alabama libraries that allows the acceptance of LC (Library of Congress) classification call numbers from OCLC cataloging into the local database without shelflisting, and describes a study that measured error rates for locally unshelflisted samples to determine the disarrangement of the local…

An automated project for converting a library collection from Dewey Decimal to Library of Congress classification was compared with a manual reclassification project. The Joint University Libraries (JUL) of Vanderbilt University, George Peabody College for Teachers, and Scarrit College served as an example of manual reclassification. The JUL…

This paper describes an experiment in the use of Dewey Decimal Classification in online catalogs to introduce classed approach to subject searching of library collections, enhance subject terminology indexed in online catalog, and provide possibilities for search strategies not possible through alphabetical approach of subject headings and/or…

Discusses the need for accurate documentation of museum holdings and the feasibility of using online library catalogs as models for automated cataloging in museums. The description of museum computer projects covers problems that have impeded automation in the past and the current status of several projects. (34 references) (CLB)

Discussion of precision in information retrieval highlights a prototype online catalog, ILSA (Improving Library Subject Access), developed at Indiana University of Pennsylvania that uses subject clusters and classification. Topics addressed include problems with keyword searching, controlled vocabulary, and thesauri; natural language mapping…

Discusses problems with subject searches in online library catalogs and examines theoretical principles for the design of effective information retrieval systems. Probabilistic ranking methods are discussed, and an experimental online catalog called CHESHIRE is described. It is noted that CHESHIRE uses classification clustering, provides natural…

This paper describes the development of an automated authority control system for the Genealogical Society of Utah, which has large holdings of microfilmed records from many nations, including civil registration, parish registers, local records, and census records. The key function of the library is the identification of people. From the…

Proposes several methods to catalog monographs that are part of collections to provide users with access to the collection as well as to the individual titles. Highlights include MARC records; online catalogs; bibliographic listings; numeric links through classification schemes; tracing links; and host-item entries. (Contains nine references.)…

Describes the Text Encoding Initiative (TEI) project and the TEI header, which documents electronic text in a standard interchange format understandable to both librarian catalogers and nonlibrarian text encoders. The form and function of the TEI header is introduced, and its relationship to the MARC record is explained. (10 references) (KRN)

This document presents guidelines for the subject cataloging and classification of hospital library materials with emphasis placed on using the National Library of Medicine's Medical Subject Headings (MeSH) and the National Library of Medicine Classification. Following an introduction, the guidelines are divided into 10 major sections: (1)…
