This third in a series of research reports on the topic of bibliographic relationships highlights linking devices used in library catalogs that connect bibliographic records for related items. Devices examined include catalog entries, i.e., main entry headings, analytical entries, cross-references, and added entries; uniform titles; and other…

Describes minimal-level, or provisional, authority records that are constructed from headings in bibliographic records as part of a computer validation process. Two types of references that can be generated automatically for authority records are explained: (1) those based on other data in the bibliographic record, and (2) those derived from the…

Analyzes four descriptive cataloging orthodoxies of the past (corporate authorship, uniform personal headings, the main entry, and the dominance of the card catalog) and contends that each has been overthrown. The influence of the MARC format on descriptive cataloging is examined and the need for the application of utilitarian principles is…

Describes a study that examined the feasibility of using machine links in an online catalog based on the presence of an OCLC control number, International Standard Serial Number (ISSN), or Library of Congress control number (LCCN) to link successive-entry serial bibliographic records that result from serial title changes. (Contains nine…

Discusses MARC records and describes a HyperCard script that translates MARC records from a communications format into an easy-to-read tagged format. An appendix lists a script from a HyperCard program called "The MARC Reader," and it is suggested that it could represent the beginning of an automated catalog. (two references) (LRW)

Describes an experimental project at Carnegie Mellon University to enhance catalog records in order to improve the quality of the records and access to resources. Criteria for selecting books for enhanced cataloging and implementation of enhancement procedures are discussed. Several sample screen displays are included. (Three references) (MES)

Discusses cataloging methods for online catalogs concerning the retrieval of works contained in collections and anthologies. Contents notes, separate added entries for each item, and the use of analytics are considered, and it is suggested that the use of analytics may be the best solution. (Author/LRW)

Discusses the composition of bibliographic record displays and their impact on library catalog use, and describes a study of 38 MARC fields and subfields in 122 Web-based catalogs to determine whether they are included in default single-record displays. Suggests directions for future research. (Author/LRW)

Describes the development and implementation of software that provides a global change capability by allowing correction of a single heading in a large file of bibliographic records through programatic identification and replacement. Specific change processes are described, including name headings, geographic headings, and topical subject…

Discusses the concept of main entry in MARC bibliographic records based on the definition in the revised second edition of the "Anglo-American Cataloguing Rules." Access points versus entries are considered; differences between card catalog and online catalog environments are examined; and primary access is suggested as an appropriate…

Describes an analysis of duplicate records in OCLC's Online Union Catalog. General and bibliographic characteristics of duplicate records are described; and reasons for duplicate records are discussed, including input errors, omission of relevant information, and differences in the interpretation of existing information. (five references) (LRW)

Describes Microlif (Microcomputer Library Interchange Format), a standard data interchange format for bibliographic information on microcomputers. Discussion includes reasons for Microlif development, differences from full MARC format, and development of the new USMARC (Microlif protocol). Members of the Microlif community are listed, and the…

This paper discusses the first major implementation of two significant new cataloging models: IFLA's FRBR (International Federation of Library Associations' Functional Requirements for Bibliographic Records) and event modeling (INDECS and Harmony). The paper refers briefly to the decision making processes leading to the adoption of these models,…

Discusses the graphical user interface (GUI) online public access catalog (OPAC), a user interface that uses images to represent options. Topics include user interface design for information retrieval; designing effective bibliographic displays, including subject headings; two design principles; and what GUIs can bring to OPACs. (LRW)

Discusses cataloging audiovisual materials and the concept of chief source of information and describes a study that compared citations from fully cataloged audiovisual records with their corresponding citations from bibliographic sourcebooks, based on records in AVLINE (National Library of Medicine's Audiovisual On-Line Catalog). Examples of…
