Abstract

The Bradford OPAC is an experimental prototype OPAC, with a graphical user interface, based on the manifestation concept. It was designed to study some of the problems in catalogues where there are many versions of the same work or complex multipart works. In place of the main entry based approach of one complete record for each item, the OPAC groups together into sets items that are manifestations of the same work. Users are presented with shorter lists of different intellectual works. Items in a set can be sorted, searched and displayed according to user supplied criteria

Abstract

Describes the technical aspects of a feasibility study to test a new concept in bibliographic control based on the manifestations of a work. Conventional catalogues are based on the main entry principle which follows from the concept that there should be 1 main entry for each work. The Bradford OPAC project, at Bradford University, UK, aimed to develop a new type of hierarchical bibliographic record structure to cope with the problem of applying the main entry principle to multiple cataloguing records which are manisfestations of the same work. The project involved the storage of MARC data sets of bibliographic records, taken from the Bradford University Library OPAC and the OCLC WorldCat database, in a relational database (MS Access) on a PC. This was then used for an experimental Windows based OPAC, to evaluate the overall success of the idea and any problem areas identified with a view to a more substantial study. The project also aimed to test whether intelligent and responsive software, using a graphic user interface and based on sets of manifestations, could provide a better route to information than a display based on a single work

Abstract

Demonstrates through case studies how authority control simply does not work. Shows how the case studies were carried out using BOPAC2 which provides facility for downloading large files and a greater range of displays than normal OPACs. Stresses that authority control is important not only to library catalogues but also to information on the Internet. Because it is so important and because it is so expensive priority action is needed to rectify the situation. Suggests a number of ways in which this might be done.

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

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

This paper describes a Research Project, funded by the British Library Research and Innovation Centre, from September 1996 to January 1998.1 The Project developed and extensively tested and evaluated a World Wide Web front end called BOPAC2 that allows access to a number of library catalogues via Z39.50 either simultaneously or individually. BOPAC2 is designed to make access to large and complex retrievals simpler. Similar records are clustered together and retrievals may be sorted in a number of ways and by different criteria. The design, development and evaluation of the system are described along with suggestions for future work

Abstract

Reviews the 20 years' evolution and development of the USBC, as a means of overcoming the weaknesses inherent in the ISBN, from its first proposal in 1974. Briefly describes the various phases of USBC's development, including: fisrt extensive testing (1977-1979); first research project (1980-82); work performed on USBC as part of proposals for the setting up of the United Kingdom Library Database System (UKLDS) (1982-84), in which USBC was to be used to create a merged retrospective database of MARC and non MARC cataloguing records; the DOCMATCH Projects, using the USBC with periodical articles (1987-89); refining of USBC by means of expert systems (1986-87); use of USBC to clean up the BLCMP database (1989-91); and the QUALCAT Project, to set up a large bibliographic database integrating records from different databases and using USBC for merging, cleaning and control and to develop an expert system to select the best record from a number of duplicates (1989-91). Reports briefly on the project, undertaken by Bradford University, Dept. of Computing, UK, to explore the application of USBC technology to the British Library Document Supply Centre's computerized interloans system. Concludes that, although the USBC has never achieved the status of an accepted standard, it has more than made for this by demonstrating its adaptibility and power in a range of situation requiring an ability to detect duplicate records and to merge and combine files
