AACR2 Rules Used in Assigning Access Points for Books in Two Subjects: Implications for Automatic Cataloging Expert Systems

Roy Meador III and Glenn R. Wittig

The cataloging rules used to establish access points for two groups of books were explored. Samples of cataloging records for books in chemistry and economics were examined to identify the clusters of rules that had been employed and that might be used in expert systems. The results were compared, and implications were drawn for automatic cataloging via knowledge-based systems.

Improving Access to New Interdisciplinary Materials

Howard Pikoff

The purpose of this study was to develop and evaluate a method for reducing the disciplinary constraints of traditional acquisitions lists. University faculty were provided an opportunity to review local Research Libraries Group acquisitions lists in subject areas of choice-across the entire Library of Congress classification schedule and to have titles of interest held for pick-up. Response to the system was highly favorable. Participants requested an average of 7 different subject lists and in 95 % of cases rated the system moderately to extremely useful.

A Taxonomy of Bibliographic Relationships

Barbara B. Tillett

A bibliographic relationship is an association between two or more bibliographic items or works. In an effort to provide the theoretical base for a conceptual model of the library catalog, past and future, the bibliographic relationship is examined here in detail. In this first of a series of reports, a taxonomy of bibliographic relationships is derived from an analysis of cataloging rules and types of bibliographic items.

The Catalog of the Deutsche Staatsbibliothek as a Bibliographical Resource

John Rutledge, Will Owen, and Frank Newton

The microfiche edition of the card catalog of the Deutsche Staatsbibliothek (German State Library) in Berlin is examined, and its use and usefulness for research libraries are evaluated. The historical development of this library of record and its collections is sketched. As a quantitative supplement to the historical facts, the study reports the results of a survey of the catalog. Comparisons with sceeral other bibliographic tools such as the OCLC database, the National Union Catalog, and the Austrian National Library catalog are made. The card catalog of the Deutsche Staatsbibliothek provides a wide range of bibliographic information not available from the other tools.

Automated Systems and Subcollection Designations

Margie Epple and Bernice Ginder

Physical subcollections within academic libraries are defined, and subcollection designations in bibliographic utilities (such as RUN and OCLC), local integrated systems, and paper catalogs, are examined. Variations in subcollection designations imposed by the automated systems are compared. Issues related to subcollection designations in an automated environment and in the transfer of subcollection designations from manual records to utilities and from utilities to local systems are identified.

A Study of Indexing Consistency between Library of Congress and British Library Catalogers

Yasar Tonta

Indexing consistency between Library of Congress (LC) and British Library (BL) catalogers using the Library of Congress Subject Headings (LCSH) is compared. Eighty-two titles published in 1987 in the field of library and information science were identified for comparison, and for each title its LC subject headings, assigned by both LC and BL catalogers, were compared. By applying Hooper's "consistency of a pair" equation, the average indexing consistency value was calculated for the 82 titles. The average indexing consistency value between LC and BL catalogers is 16 % for exact matches, and 36 % for partial matches.

Preservation Microfiche: A Matter of Standards

Myron B. Chace

Standards for converting library materials to a microfiche format are described, and the question of whether microfiche standards take preservation concerns into account is raised.

User Acceptance of Library Catalog Results: An Exploratory Study

Tschera Harkness Connell

This study explores whether a student user is more likely to believe the results obtained from an online system than from a manual system. Findings indicate that, overall, they are equally likely to believe either system. However, students' familiarity with the title searched made a difference. Students who had heard of a book but found no record for it were more likely to distrust the computer. When the book was unfamiliar and no record was found, they were more likely to distrust the card catalog.

Analysis of Selection Activities to Supplement Approval Plans

Jean L. Loup and Helen Lloyd Snoke

In 1986, 28 Association of Research Libraries (ARL) member libraries were surveyed for information about their use of approval plans for materials in philosophy and political science. Additional information was obtained concerning activities used to supplement their approval plan acquisitions. A second survey to follow up on the supplemental activity was conducted in early 1988. This paper describes the results of the two surveys, results that indicate the importance of supplemental activity in building research library collections. Implications for participation in resource sharing are explored.

Personal Name Variations: Implications for Authority Control in Computerized Catalogs

Tamara S. Weintraub

The effects of personal name variations on authority control and data retrieval in computerized catalogs are explored by studying the names of 395 persons receiving entries in the catalog of the University of California at San Diego libraries. Although 63% of the people receive entries for more than one title, nearly 82% of all persons have only one name form in all bibliographic transcriptions and the authority records of approximately 67% contain no references. Of those with only one transcribed form of name, 45 % receive entries for 2 or more titles and the authority records of nearly 62% contain no references. Fullness of forename is the most common variation among multiple names for the same person. Enhanced search and retrieval programs will collocate bibliographic records associated with most individuals without the assistance of a full MARC authority file, even if a person's name varies in bibliographic transcription or controlled headings and references. Few local control problems are expected with abbreviated authority files.
