Abstract

Presents a brief report on a study, carried out by the Centre for Interactive Systems Research, City University, to investigate the techniques used for evaluating OPACs: to explore and assess different data gathering methods in studying information seeking behaviour at the on-line catalogue; and to examine how a transaction logging facility could be enhanced to serve as a more effective diagnostic tool.

Abstract

Standards for user interfaces for access to bibliographic data bases cannot be developed without more complete understanding of the current user, user attitude and capabilities. Gives 3 means of achieving this based on observing the user. 45% of access points in subject searches results in no retrievals. Errors in searching on-line catalogues occur with a 40% no hit title search rate and a 51% no hit author search rate when those records were on the data base. Stresses the importance of fundamental user interface components contained in the IBM staff publication systems guide. Concludes that although there is no such thing as a standard user it is still vital to develop user standards

Abstract

Modern online information systems have been criticized as being too complicated for the average information seeker. To overcome this problem interfaces have been developed to assist users at all stages of the information transfer process from searching to analysis and evaluation of retrieval data. However, the effectiveness of an interface will depend on the skills of the user. Further development of interfaces will be aided by the use of Windows and mouse controlled systems

Abstract

User interfaces for CD-ROM products in the academic library environment must accomodate a variety of user and task profiles. Discusses the practical considerations that govern the implementation of interface design principles for such electronic data bases under the following headings: redesign goals; interaction style; menu design and implementation; system structure and the search paradigm; basic system operation and screen layout; simplified features; integrated novice and expert mode; redesign constraints; and hardware and software constraints

Abstract

Presents the selected findings of a research project based on the British Library Network Online Public Access Catalogue (NOPAC) carried out in the department of information and library management at the University of Northumbria in Newcastle, UK over the academic year 1994/95. Data was collected by means of interviews with NOPAC users especially on use made of the NOPAC and on attitudes towards the NOPAC's interface. Discusses the views of users as they relate to: display features; mode of interaction; help/user assistance; extra features available; and usability. Lists important points which emerged from the survey concerning the NOPAC service

Abstract

Information retrieval systems such as library OPACs have been largely designed to give the impression of being single user systems, the existence and activity of other users being hidden from each other. However, informal observations indicate significant collaboration between users despite the fact that existing systems fail to support this. Describes the development of an interface, the Ariadne system, that supports collaboration through the storage and re-use of others' search processes promoting better visualization of the information data structures being browsed and more effective means of communicating the browsing process. Discusses issues relating to privacy and ownership resulting from the storage of users' searches. Argues that introducing support for collaboration into information retrieval systems would help users to learn and use the systems more effectively

Abstract

Current research on user interfaces to online public access catalogs is reviewed in an attempt to identify research methods and findings applicable to the design of effective user interfaces to online public access catalogs. A broad definition of user interface is employed which includes data structures, in addition to searching and indexing software. The following features of online public access catalogs are discussed: the demonstration of relationships between records, the provision of entry vocabularies, the arrangement of multiple entries on the screen, the provision of access points, the display of single records, and the division of the catalog into separate files or indexes. For each feature, user studies and other research on online public access catalogs are reviewed and those findings summarized which provide insight into user needs concerning that particular feature; issues are identified and directions for further research are suggested. Implications for cataloging codes and standards and system design are discussed

Abstract

Decribes the BookHouse, a system for the retrieval and indexing of fiction and non fiction literature developed for public and school libraries though cooperation between library and information science professionals. Discusses 3 aspects of the system: domain characteristic; task analysis; and user characteristics. Outlines the framework underlying the collection of field data with special emphasis on the work involved in transforming the empirical field studies of user behaviour in the library into computer system specifications and subsequent design of a retrieval system providing subject access to fiction. Describes a few of the many indexing policies, rules and practices which evolved for concept identification and book descriptions as well as the functionality and associated displays of the system for supporting the retrieval and indexing of fiction
