Content-enriched metadata in bibliographic records is considered helpful to library users in identifying and selecting library materials for their needs. The paper presents a study, using circulation data from a medium-sized academic library, of the effect of content-enriched records on library materials usage. The study also examines OPAC search…

This paper presents a comparative evaluation of Google Scholar and 11 other bibliographic databases (Academic Search Elite, AgeLine, ArticleFirst, EconLit, GEOBASE, MEDLINE, PAIS International, POPLINE, Social Sciences Abstracts, Social Sciences Citation Index, and SocINDEX), focusing on search performance within the multidisciplinary field of…

In this article, the authors compared the MLA International Bibliography database (MLAIB) across five vendor platforms to determine how and why seemingly comparable searches produced varying results. A number of tests were conducted using a variety of fields, terms, and parameters, and examples of results are provided. The authors' findings are…

Argues that users' needs should play a more prominent role in the design or choice of an online catalog in a specific library, and outlines requirements which enhance ease of use. Areas discussed include operational control, search formulation control, access points, output control, user assistance, and hardware requirements. (nine references)…

The purpose of this study was to examine the inter-indexer consistency in the assignment of selected access points between OCLC and RLIN (Research Libraries Information Network). Both databases are used by many libraries as bibliographic sources for copy cataloging. Access points were compared for differences in wording, MARC coding, and…

Developed at the beginning of the decade to serve as a union catalog for identifying the holdings in all University of California (UC) libraries, the MELVYL online catalog as of October 1989 contained 10 million holdings for over 5 million monographic titles of print and nonprint materials, and more than 1.2 million periodicals holdings which…

Describes a project that examined the effects of incorporating subject terms from the Dewey Decimal Classification (DDC) into a bibliographic database. It is concluded that the incorporation of DDC and possibly other library classifications into online catalogs can enhance subject access and provide additional subject searching strategies. (11…

This guide was developed to support Internet access to library catalogs at the University of Georgia (UGA). Since the UGA Libraries can only connect to the Internet using TELNET 3270 emulation, this guide is restricted to library systems which support that protocol. Section 1 of the guide presents the commands that are needed to gain access to the…

Describes an investigation of tools, techniques, and methods for the evaluation of interactive library catalogs, with emphasis on diagnostic methods and on use of the catalog in the wider context of user information-seeking behavior. A front-end system (Olive) developed to test various enhancements of traditional transaction lodging as a…

Describes the Dewey Online Retrieval System (DORS), which was developed at the University of California, Los Angeles (UCLA), to experiment with classification-based search strategies in online catalogs. Classification structures in automated information retrieval are discussed; and specifications for a classification retrieval interface are…

Describes the State of Iowa Libraries Online project (SILO) which was developed to demonstrate new information technologies available to libraries. Focuses on two interlinked components of the project: Web-based union catalog development and statewide deployment of the ANS/NISO Z39.50 information retrieval standard. Includes recommendations for…

Describes a study conducted at the University of Illinois to test the effectiveness of subject access in the online bibliographic catalog. Relevance is examined and possible methods of improving subject access are described. Results suggest that significant improvements are not possible within the constraints of existing subject cataloging…

This book is designed to assist the beginning searcher of those online systems that primarily provide information in the form of bibliographic citations. These systems also contain files in other formats that are designed to provide answers to reference-type questions. It is intended not only to provide basic "how-to" information on the…

Describes the design of a prototype adaptive online catalog that was implemented as a transparent workstation-based front end system to MELVYL, the online catalog for the University of California libraries. Problems with searching bibliographic retrieval systems are reviewed, including irrelevant retrievals and the inexperience of most users.…

Discusses the Science Library Catalog, an online catalog intended for use by children at the Los Angeles Public Library, and describes the process of reorganizing the MARC-based database by using clustering algorithms to extend the Dewey Decimal Classification. Examples of screen displays are included. (18 references) (LRW)
