Abstract

Reports on a continuing project to study children's use of a graphically-based direct manipulation interface for science materials. The Science Library Catalogue (SLC), a component of project SEED, has been implemented in the libraries of 21 elementary schools in Los Angeles and will soon be implemented in a public library. The interface employs a hierarchical structure drawn from the DDC and implemented in HyperCard on the Macintosh. The study on the 2nd version of the interface indicates that children are able to use the Science Library Catalogue unaided, with reasonable success in finding items. Search success on the same topics on a Boolean command driven system was equivalent, but Boolean searches were faster. However, the Boolean system was more sensitive to differences in age, with 12-year-olds having significantly better success rates than 10-year-olds; and to search topic, with one set of questions being much easier to search than the other. On average, children liked the 2 systems about the same; the Boolean system was more attractive to certain age and gender combinations, while the Science Library Catalogue was more consistently liked across groups. results are compared to prior studies on the Science Library Catalogue and other online catalogues

Abstract

Outlines the progress of HyperLib, research which began in 1993 to develop a hypertext interface to the online catalogue and other databases at the University of Antwerp. A human factors oriented design methodology was adopted. A user survey was carried out. The project has focused on development of electronic guides and manual and interfaces to access an academic bibliography database and the UDC subject classification scheme. Evaluation is being carried out in 1995

Abstract

The Hyperlib project, which is a joint, EC-funded project, between the libraries of Antwerp and Loughborough universities, aims to investigate the opportunities for a hypertext-structured catalogue at Antwerp University. Essential to the project was a survey of user requirements. Because of time constraints, however, it proved impossible to develop a full hypertext-structured database. As a result of the project a redesigned OPAC will be implemented in Spring 95, which will include individual journal article sand the opportunity to create personalised menu-structures

Abstract

Presents a prototype for a hypertext-based library catalogue using the experience of the Department of Information Science at the University of Graz and the Department of Library and Information Sience at the Eötvös-Lorand University, Budapest. Following an historical overview of the development of the hypertext concept and the benefits resulting from a hypercatalogue, the hypertext structure of the catalogue and its functionality are described. Prospects for the future are also outlined

Abstract

Describes a hypertext-based system that integrates the bibliographic information of the library catalogue with user-defined knowledge structures, imports information at the user's command, and offers a dynamic personal information tool for active users. Describes the structure and the content of the data base, and shows how the system can be accommodated to different user groups or individual users.

Abstract

The paradigm shift from the old system centered view to a user centered approach involves new tools needed for accessing library resources under the condition that the user's needs are taken into account. An end-user, who has only a little knowledge of classification systems or thesauri, understands little of the mode of the representation of contents and the use of authority lists. In addition, he will have difficulty in formulating his question in a precise manner. He needs to know better what the library proposes in order to define of what use it would be for him. Many studies have been carried out on the use of controlled vocabularies (classification, authority lists, thesauri) as searching devices. It is surprising to find that relatively little attention has been given to the role of these tools in filtering and browsing processes. We have developed a prototype named CATHIE (CATalog Hypertextuel Interactif et Enrichi) that supports such filtering and interactive reformulation features
