- Abstract
- A project to design a graphical user interface for the OKAPI online catalogue search system which uses the basic term weighting probabilistic search engine. Presents a research context of the project with a discussion of interface and functionality issues relating to the design of OPACs. Describes the design methodology and evaluation methodology. Presents the preliminary results of the field trial evaluation. Considers problems encountered in the field trial and discusses contributory factors to the effectiveness of interactive query expansion. Highlights the tension between usability and functionality in highly interactive retrieval and suggests further areas of research

- 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
- The destabilizing influences of the Web, widespread ownership of personal computers, and rising computer literacy have created an era of discontinuous change in research libraries a time when the cumulated assets of the past do not guarantee future success. The library catalog is such an asset. Today, a large and growing number of students and scholars routinely bypass library catalogs in favor of other discovery tools, and the catalog represents a shrinking proportion of the universe of scholarly information. The catalog is in decline, its processes and structures are unsustainable, and change needs to be swift. At the same time, books and serials are not dead, and they are not yet digital. Notwithstanding widespread expansion of digitization projects, ubiquitous e-journals, and a market that seems poised to move to e-books, the role of catalog records in discovery and retrieval of the world's library collections seems likely to continue for at least a couple of decades and probably longer. This report, commissioned by the Library of Congress (LC), offers an analysis of the current situation, options for revitalizing research library catalogs, a feasibility assessment, a vision for change, and a blueprint for action. Library decision makers are the primary audience for this report, whose aim is to elicit support, dialogue, collaboration, and movement toward solutions. Readers from the business community, particularly those that directly serve libraries, may find the report helpful for defining research and development efforts. The same is true for readers from membership organizations such as OCLC Online Computer Library Center, the Research Libraries Group, the Association for Research Libraries, the Council on Library and Information Resources, the Coalition for Networked Information, and the Digital Library Federation. Library managers and practitioners from all functional groups are likely to take an interest in the interview findings and in specific actions laid out in the blueprint.

- Abstract
- The aims of the QUALCAT project were to: set up a large bibliographic database integrating records covering a range of material from a number of different databases by using USBC technology for cleaning, merging and control, develop an expert system to select the best records from a number of duplicate records; develop an expert system to link databases and centralized authority control; develop a fully automated quality control package for day to day running; and investigate interface problems for cataloguers using the system

- Abstract
- The OPAC has developed into an information providing tool capable of many varied tasks. Maps this development. Discusses the interface between the OPAC and the casual or inexperienced user and the expending use of networks. Surveays the growth of OPACs and shows that OPACs have developed a number of features from information retrieval. Assesses areas of further research

- 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 work of the BOPAC2 project, funded by the British Library Research and Inoovation Centre, from Sep 1996 to Jan 1997, to investigate the issues involved in managing large and complex retrievals involving Z39.50 searches, including searches of multiple databases. The system is a WWW front end that allows simultaneously access to a number of library OPACs via Z39.50. The system is designed to make access to large and complex retrieval simpler, similar records are clustered together and retrievals may be sorted in a number of ways and by different criteria. Describes the design, development and evaluation of the system with suggestions for future work
