- Abstract
- The ENQUIRE project forms part of a series of investigations on query expansion in the Okapi experimental text retrieval system. A configurable user interface was implemented as an evaluative tool and tested in two locations on two different databases: the library catalogue of The London Business SChool and the computing section of INSPEC. The system offered a range of possible strategies based on thesaural terms for reformulating queries. These could be initiated automatically by the system or interactively with the user. The formative phase of the evaluation established the appropriateness and usability of the interface as well as users' perceptions of the underlying functionality. The aim of the large scale field trial was to determine to what extent user would select thesaural terms suggested by the system to reformulate queries, and to evaluate the effectiveness of a new dynamic form of query expansion implemented for this project

- 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
- Describes the RUBIKON on-line catalogue (OPAC) at Roskilde University Library, Denmark, and the auxiliary search tool, proposed by the library, designed to give better search facilities and handle 'no hit' situations. The tool consists of a search command which expands a search by consulting various types of lexical reference records and performs a series of Boolean OR searches on items from the list. Proposes 3 types of lexical reference records: name records; terminological help records; and classification schedule records

- Abstract
- The use of library resources will no longer be restricted to the physical location of libraries thanks to networking technologies and standard protocols for information retrieval. These technical achievements allow users to access geographically scattered libraries but they do not ease their intellectual access. Indeed, users need a certain command of different languages to find publications whose records are written in a unique language. Multilingual facilities, including multilingual presentation and retrieval, can intellectually open the library catalogue to a wider range of international users. Describes an attempt at using multilingual resources with a view to improving user OPAC interaction through the TRANSLIB project, which provides library users with advanced tools that support multilingual access

- Abstract
- Describes a feasibility study funded by BLRDD to test a new concept in bibliographic control in OPACs based on the manifestation of the work. The research was conducted at Bradford University, leading directly from the QUALCAT project, and used bibliographic records supplied by OCLC. A new type of hierarchical bibliographic record structure was used to import sets of bibliographic records into a hierarchical relational database. This was used for an experimental Windows based OPAC. Much of the early part of the project was spent clarifying the practical and theoretical implications of the manifestations concept

- Abstract
- Describes the OKAPI projects and OKAPI's development as an experimental online catalogue system over 10 years, first at the University of Westminster (formerly the Polytechnique of Central London) and subsequently at City University, London. The 1st OKAPI project in 1984 introduced 'best match' retrieval and focused on the user interface design. The 2nd investigated word stemming, spelling correction and cross reference tables as retrieval aids. A comparative study of 2 library catalogues was undertaken in 1987, while in 1988 query expansion and relevance feedback were introduced and evaluated by laboratory tests. In 1990 live evaluation of automatic query expansion was carried out and in 1993 subject enhancement of bibliographic records was investigated. The latest project has examined the design of a graphical user interface to support interactive query expansion. Discusses the research and evaluation of each project

- Abstract
- Reports the results of a research project, conducted by the School of Computing and Mathematics and the Library of Huddersfield Polytechnic, into the problem of matching the user interface of OPACs to the needs of users. The project brought together issues involving: Human Computer Instruction (HCI); system methods in the determinination of user requirements; and user centred design, and prototyping in a sequence of design and evaluation cycles. These cycles applied appropriate HCI styles, techniques and equipment (such as Graphical User Interface (GUI) and a mouse pointing device) and incorporated the lessons of each evaluation, to produce an OPAC user interface, ICARUS, which differs considerably in style, behaviour and characteristcs from those commonly encountered in academic and public libraries. The project concluded by evaluating ICARUS, against the BLCMP OPAC with 38 subjects in the Library of Huddersfield Polytechnic, and demonstrating a significant improvement in performance for different tasks for the ICARUS interface

- Abstract
- Provides a brief summary of an OCLC funded project 'Identifying barriers to effective subject access in library catalogues'. The study investigated the probability that a skilled catalogue user would retrieve 'the best' materials on some subject, and if they were unable to do so, to determine how this could be improved. The transformation of the card catalogue onto an online database has not improved subject access. Offers a view of research in the context of the education and research roles of the library and information science educator. Discusses the university research environment, teaching students research skills and OCLC

- Abstract
- One of the most common errors in cataloguing library materials involves miscoding of the nonfiling indicator of title fields. Notes the extent of the problem and its negative effect on searching in the library's online catalogue and surveys how librarians have approached solutions to the problems. Describes how the major library automation system address this problem

- Abstract
- The primary objective of the present study was to exmine whether readers conducting bibliographic searches in ALEPH - Israel's research library network - tend to search only within the OPAC of the library within which they are working or whether they access the remote OPACs of other libraries. The ALEPH network has a dezentralized database. Therefore, it was possible to examine this question because each library has its own access code and each database can be searched separately. The data were collected by means of a one-page questionnaire lefr beside each terminal in the library of the Graduate School of Library and Archive Studies of the Hebrew University of Jerusalem during an entire academic years. results of analysis of the data collected in this survey are presented in 6 tables

- Abstract
- Reviews the development of the British Library OPAC services leading up to the launch of OPAC 97, offering access to 9 mio bibliographic records and attempts to show the value of a user centred approach in the project management involved in developing such a service as recommended by Human Computer Interaction (HCI) studies. Reviews the evaluation studies of the Online Catalogue, the Network OPAC, a web prototype interface and of OPAC 97 and discusses the results in relation to the OPAC 97 project. Although the OPAC 97 interface made use of various HCI recommendations, user feedback sometimes contradicted these in specific instances, revealing the value of detailed user evaluation in developing services

- Abstract
- Reports results of an evaluation study of 3 WWW based prototypes for bibliographic displays developed as part of an ongoing research project at the Faculty of Information Studies, Toronto University. The development of these prototypes builds upon results obtained in earlier phases of the project that addressed issues of both the content and form of bibliographic displays in OPACs. Anticipation of continued growth in the number of catalogues available through the WWW, combined with research evidence that existing Web based displays have not shown improvement over their text based counterparts, motivated the development of these prototypes for use on the Web. Reports findings from a focus group evaluation of the 3 prototypes and makes suggestions for future research

- Abstract
- Presents some results from research into the uses and usefulness of electronic bibliographic databases in academic contexts, carried out as part of a British Library funded research project. Ethnographic and focus group data was gathered initially in 3 departments (natural science, social science and humanities) at the University of Kent at Canterbury covering all academic staff, researchers and postgraduates. This was then expanded to postgraduates and staff in the same 3 disciplines at other universities. 5 themes from this research are outlined: who uses the system, who does not, and where are these activities and inactivities happening; where does formal training occur; and where does learning occur. The problems of interface between computer systems and users often mirrored that between library enquiry staff and users where users did not know to frame questions and the advice given was not in a form understood by the users
