Do students prefer to use Google instead of the library catalog? Ever wondered why? Google is easier to use and delivers plenty of "good enough" resources to meet their needs. The current generation of online catalogs has two main problems. First, the look and feel of the interface doesn't reflect the conventions adhered to elsewhere on the web,…

Purpose: The purpose of the paper is to examine the various features and components of web-based online public access catalogues (OPACs) of IIT libraries in India with the help of a specially designed evaluation checklist. Design/methodology/approach: The various features of the web-based OPACs in six IIT libraries (IIT Delhi, IIT Bombay, IIT…

Describes a study that examined the effectiveness of implied boolean searches using personal author surnames plus first and/or last title words to retrieve an entry from a simulated online public access catalog (OPAC). Implications for the design of OPACs are discussed, and further research is suggested. (LRW)

A microcomputer-based user interface was developed and programmed for the library computer systems at the University of Illinois. Designed to provide user-friendly access to the two components of the online catalog on the library's IBM 3081 mainframe computer, the interface program resides on the IBM PC and queries the user in natural written…

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)

A study was conducted that used transaction logs to identify the characteristics of the most complex or problematic user queries. Enhancements are recommended in the design of online catalogs that use search trees to control system responses and to determine appropriate subject-searching terminology and technique. Contains 21 references and 12…

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 study that examined subject searchers' use of a display of terms related to their topics as provided through online display of authority information from Library of Congress subject headings. The need to encourage searcher use of available syndetic structures is discussed. (17 references) (Author/CLB)

Describes a study that electronically monitored 11 public access terminals at the University of Colorado libraries to produce transaction logs that were used to gather statistics and analyze users' behavior when searching online catalogs. Implications for search instruction and systems design are suggested. (Contains 13 references.) (LRW)

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,…

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…

Libraries faced with the challenge of cooperative cataloging must maintain a high degree of unification within the library network (consortium) without compromising local libraries' independence. This paper compares a traditional model for cooperative catalogs achieved by means of a Union Catalog that depends entirely on replication of data…

What would it take for libraries to provide their patrons with the same kind of success in finding information using their resources as they achieve with Google, and as quickly? This author asserts that the answer is not that complicated: be more like Google, and then move beyond Google. With the technology available right now, this is not an…

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 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.…
