Discusses the shortcomings of present online catalogs and some concepts and implementations for hypercatalogs. A prototype for a hypertext-based library catalog, HyperKGB, is described and its design principles and functionality are outlined. (Author/AEF)

Describes the University of California at Berkeley's participation in the TREC (Text Retrieval Conference) interactive track experiments. Highlights include results of searches on two systems, Cheshire II and ZPRISE; system design goals and implementation; precision and recall results; search questions by topic and system; and results of…

Discussion of problems with retrieval of records in library online public access catalogs (OPACs) focuses on an ongoing research project at the Indiana University of Pennsylvania (IUP) that has been trying to improve subject retrieval vocabulary control using natural and thesaural language and on the design of a good graphical user interface.…

Reviews the characteristics of the Cheshire II system that is being used to implement full-text and fielded searching of bibliographic information for the University of California Berkeley Digital Library Initiative. Examines its performance when applied to a collection of large full-text documents in the TREC Interactive Retrieval Track and its…

Describes a project designed to provide bibliographic control and access through use of the Text Encoding Initiative (TEI) Header and MARC record to electronic texts coded with Standard Generalized Markup Language (SGML). Steps in the cataloging process, efforts to refine the process, and the issues the process raises are discussed. (16…

Discusses features of online public access catalogs: (1) demonstration of relationships between records; (2) provision of entry vocabularies; (3) arrangement of multiple entries on the screen; (4) provision of access points; (5) display of single records; and (6) division of catalogs into separate files or indexes. User studies and other research…

This paper describes the techniques for implementing a full-screen, custom SPIRES interface for a public-use library database. The database-independent protocol that controls the system is described in detail. Source code for an entire working application using this interface is included. The protocol, with less than 170 lines of procedural code,…

Discusses the human-computer interface as it relates to information technology and retrieval. Principles of interface design are examined, including visual display features and help messages; information retrieval applications are described, including online searching, CD-ROM, online public access catalogs (OPACs), and full-text databases; and…

Analyzes the change that Internet-based OPACs (Online Public Access Catalogs) have represented to the structure, administration, and maintenance of the catalogs, retrieval systems, and user interfaces. Examines the structure of databases and traditional principles that have governed systems development. Discusses repercussions of the application…

Describes the comparative approach to system evaluation used in a project which administered an online retrieval test to an experimental online catalog to produce data for evaluating effectiveness of a new subject access design. Discusses efforts used to ensure data reliability, and strategies the researchers can use to improve on the data…

Discussion of library information systems focuses on the idea of including user-supplied data (USD) in libraries' automated catalogs. Hypertext is mentioned, the information explosion and the ability to selectively retrieve information is considered, and the value of user input in evaluating the relevance of material is discussed. (12 references)…

This paper describes the IFLA (International Federation of Library Associations and Institutions) guidelines for librarians charged with customizing OPAC (online public access catalog) software and vendors and producers of this software. The guidelines are intended to apply to all types of catalog, including World Wide Web-based catalogs, GUI…

E-Referencer is an expert intermediary system for searching library online public access catalogs (OPACs) on the World Wide Web. It is implemented as a proxy server that mediates the interaction between the user and Boolean OPACs. It transforms a Boolean OPAC into a retrieval system with many of the search capabilities of Web search engines.…

This article studies the performance of online catalog user queries involving personal names and recommends system improvements based on the results. It examines various personal name queries, the construction of bibliographic data, and subject headings. Testing done on an experimental online catalog found search tree designs to reduce system…

Describes the system architecture and user evaluation tools for Cheshire II, an online catalog and full-text information retrieval system being developed at the University of California, Berkeley, that uses advanced information retrieval techniques to overcome the problems of topical searching in online catalogs, search failure, and information…
