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…

The dictionary catalog is described as a logical answer to the inadequacies of the divided catalogs ofthe nineteenth century. The claims in behalf of a return to the divided catalog are challenged. (Author/NH)

The question of whether a library's catalog should consist of cards arranged in a single alphabetical order (the "dictionary catalog) or be segregated as a separate file is discussed. Development is extended to encompass related problems involved in the creation of a book catalog. A model to study the effects of congestion at the catalog is…

A study was made of the effectiveness of the Midwest Medical Union Catalog (MMUC). The literature on union catalogs characterizes the objectives and procedures of such catalogs, but gives little reliable data about costs and rarely focuses on traffic. The objective of this study is to determine whether the cost of the MMUC is justified by its…

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…

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,…

Experiments were designed and carried out in an attempt to identify some parameters relating to ease of manual searching in library catalogs. A comparison of the difficulty of searching the same file in card form and book form indicated that searching the book catalog generally requires more time. (4 references) (Author/NH)

Describes a project at the Princeton University libraries that converted the pre-1981 public card catalog, using digital imaging and optical character recognition technology, to fully tagged and indexed records of text in MARC format that are available on an online database and will be added to the online catalog.

A semi-humorous article suggesting that libraries should have both a dictionary catalog and a divided catalog. The author also suggests additional card catalogs, such as a people catalog and a place catalog. (Author)

This paper attempts to analyze the problem of congestion, using a mathematical model shown to be of value in other similar applications. Three criteria of congestion are considered, and it is found that the conclusion one can draw is sensitive to which of these criteria is paramount. (8 references) (Author/NH)

Reviews problems for users created by the complexities of past practices for filing catalog cards, and describes some features of the new, more user-oriented ALA filing rules. (LLS)

Provides current descriptions of some of the major directories that link to library catalogs on the World Wide Web. Highlights include LibWeb; Hytelnet; WebCats; WWW Library Directory; and techniques for finding new library OPAC (online public access catalog) directories. (LRW)

A truly global supply of bibliographic records and the emergence of online publishing put new challenges on the organization of bibliographic control. Three important cataloging codes are presently under revision, the AACR, the Italian RICA and the German RAK. The basis for a record, the carrier=content dichotomy, is one fundamental issue which…

Describes the debate over the discarding of card catalogs once automated, online library catalogs are implemented. The discussion focuses on the classified catalog of the Science and Technology Department at the Carnegie Library of Pittsburgh. The neglected state of library archives and historical developments in library catalogs are considered.…

Twenty-nine questions to be asked before deciding on a book catalog are presented with comments based on the experience of the Baltimore County Public Library. The assumption made throughout this paper is that the work will be done by computer. (Author/NH)
