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…

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 online help systems in online public access catalogs (OPACs) focuses on a study that evaluated the online help system for the NOTIS (Northwestern Online Total Integrated System) OPAC. Features of the system reviewed include online functions; training features; general interface features; access points; and message content and display…

Discusses methods of browsing in online public access catalogs (OPACs) and describes one method that uses information pertaining to the physical description of books from MARC records to simulate images of books on a library shelf. Electronic browsing through MARC is discussed, and methods of enhancing OPACs are reviewed. (51 references) (LRW)

Traces the development of online public access catalogs (OPACs) and compares what has occurred with a 1964 article that outlined recommendations for a future card catalog. Subject access is emphasized, including Library of Congress Subject Headings, expansion of OPACs, user-friendly interfaces, new technologies, and current visions of the future…

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…

Discusses how archivists use the MARC AMC (Archival and Manuscripts Control) format for descriptive information about archival materials. Modifications that MARC AMC introduced to the standard MARC bibliographic formats are explained, and examples of a record in AMC formats on different bibliographic utilities are given. (24 references) (LRW)

Reviews methods to improve online catalogs for subject searching and describes the design of an expert system front-end to improve subject access in online public access catalogs that focuses on search strategies. Implementation of a prototype system at the National University of Singapore is described, and reformulation strategies are discussed.…

Presents a conceptual model for an enhanced online public access catalog (OPAC) called SuperPAC, which includes features that allow users to critically evaluate the information they encounter. Two features are described: the integrated availability of electronic evaluative resources and the use of improved MARC records. (Contains 22 references.)…

Discusses the history of American and British experiences with library automation and contrasts them with recent developments in central and eastern Europe.
