Hierarchical Relationships in the Bibliographic Universe
ABSTRACT: The hierarchical relationships among bibliographic entities include whole-part structures and the Functional Requirements for Bibliographic Records (FRBR) hierarchical relationships among works, expression, manifestations, and items. The traditional MARC (Machine Readable Cataloging) format falls short in representing these hierarchical relationships. Based on detailed analyses of these hierarchical relationships and an examination of Metadata Encoding and Transmission Standard (METS) and Encoded Archival Description (EAD), which are well suited for hierarchical description, the author proposes some features of a new data structure standard named Resource Description Metadata Schema (RDMS). New cataloging practices based on RDMS will bring bibliographic description closer to archival description, and take one step further toward merged descriptive practices for bibliographic and archival materials.

Subject Indexing Trends in Libraries of the National Autonomous University of Mexico (UNAM)
ABSTRACT: The purpose of this work is to highlight policies promoted by the practice of subject indexing within an information system pioneered in Mexico and to propose the inclusion of prevailing cultural trends regarding linguistic context. The method used is analysis of historical evolution in a descriptive longitudinal study of policies and practices in the field. The result shows that the historical practice in Mexico of following international subject indexing trends based on the English language is no longer viable. New processes must take into account sociocultural usage and linguistic context and encourage the development of documentary languages and sources.

The Relationship of Metadata to Item Circulation
Laura N. Kirkland
ABSTRACT: This study analyzes the relationship between online public access catalog (OPAC) searches entered in a small academic library's catalog and the circulation of items during the same time period. Rather than identifying all searches resulting in a reasonable number of retrievals as successful, searches in this study were determined most useful if items on the results list were subsequently borrowed from the library. This comparison of search results with subsequent material checkouts indicates which metadata elements seem most useful to searchers, and suggests ways libraries might use this knowledge to enhance their users’ search experiences

The Development and Application of U.S. Descriptive Standards for Archives, Historical Manuscripts, and Rare Books
Cory L. Nimer & J. Gordon Daines III
This article gives an overview of the descriptive and technical standards used in the archives, historical manuscripts, and rare books communities in the United States. It briefly examines the conceptual models underlying these standards and then describes how they have been implemented in the L. Tom Perry Special Collections at Brigham Young University.

PCC Practice for Assigning Uniform Titles for Television Programs: Principle versus Practice
Peter H. Lisius
Library of Congress Rule Interpretation (LCRI) 25.5B, Appendix I contains Program for Cooperative Cataloging (PCC) principles for constructing uniform titles for motion pictures, television, and radio programs. Originally designed for PCC libraries in providing uniform title access for these materials, it has also been adopted by non-PCC institutions. Focusing on uniform title access for television programs, this article will show that these PCC principles have largely been unapplied; and, when they are applied, it is principally by non-PCC institutions. The article concludes with a discussion on the future application of these principles for preferred access points in Resource Description and Access (RDA).

Aggregate and Component Entities in RDA: Model and Description
Based on the distinction between model and description in Resource Description and Access (RDA), the modeling and description of aggregate and component entities in RDA was examined. Guidelines and instructions related to such modeling were extracted from RDA and reconciled. After introducing additional assumptions, five possible model patterns of aggregate and component entities were developed. Then, the mapping between these model patterns and the manifestation types was clarified, revealing which model patterns are applicable to a given type of manifestation. Finally, RDA instructions on descriptions for aggregates/components were examined, and it was clarified that they do not have any conflict with the modeling.
