This article presents a case study in user-centered design that explores the needs and preferences of undergraduate users. An analysis of LibQual+ and other user surveys, interviews with public service staff, and a formal American with Disabilities Act accessibility review served as the basis for planning a redesign of the Brown University…

Discusses the need for online help for end-users based on experiences with an online public access catalog (OPAC) at the University of Cape Town libraries. The concept of end users is examined, the role of search intermediaries in information systems is explained, and online help and systems design is discussed. (LRW)

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…

Describes ANLI (Adaptive Network Library Interface), an interface to an academic library's online catalog that links documents through interactions with users. Topics addressed include relation to neural networks; system design issues, including network management; the architecture of the ANLI; and the ANLI as a research tool. (Contains five…

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)

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…

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 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.…

Presents an Intelligent Negotiating Neural Network Design Model for solving the problem of poor information retrieval in subject searches of online catalogs. The purpose of the network, its architecture, and three different sessions of the user interface are described. Nineteen figures showing screens of the three sessions are appended. (Contains…

Three user interfaces to LIBIS, a library catalog accessible through the Internet, were evaluated for use by people who are motor impaired to identify how interface design influences the motor actions necessary to operate the system. Problems and recommendations related to simplicity, consistency, instinctiveness, interaction/feedback, and…

The papers in this proceedings consider ways in which user friendly interface design may be used to make online systems in public and academic libraries easier to use, and thus more attractive to potential users. A short introduction by F. W. Lancaster is followed by nine papers: (1) "Linking the Unlinkable" (Michael Gorman); (2)…

Results are reported from a study that investigated the extent to which academic library end users conducted multiple search sessions with online public access catalogs or CD-ROM databases at different stages of their information seeking related to a research project. Implications for training, retrieval systems design, and further research are…

Examines the current state of user interface design for information seeking. Topics include technology push and interdisciplinarity; research and development; literature trends; user-centered interface design; information seeking in electronic environments; online information retrieval system interfaces; online public access catalog interfaces;…

This report on options for developing the University of California (UC) MELVYL online library system discusses the system in relationship to the current environment, including national and network information resources, electronic publishing, campus libraries, and changing user expectations; and places the growth of the MELVYL system in the…
