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

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

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

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

Abstract

This article describes cooperation between Bradford University Library and the Department of Computing that has resulted in nine research projects over a twenty five year period on various aspects of bibliographic control. It recounts the origins of the Universal Standard Bibliographic Code (USBC) and its development for the identification of both books and non book material. It then describes various aspects of the projects including simulating the merging necessary to set up a national database, the cleaning of a database, its use in inter library lending, and its application together with expert systems for the quality control of databases. The final project is BOPAC that has used modern technology to create faster and better access to a number of library catalogues worldwide and has demonstrated that authority control in its present form is not effective.

Abstract

Three factors are likely to force dramatic changes in the libraries of the future. They are the increase in electronic publishing, the digitising of conventional library materials, and the Internet which is creating a second information revolution. New concepts are needed for cataloguing functions in the Internet environment. Cataloguing, now a pre-coordinate function should shift to a post-coordinate activity. Authority control should become an activity of the searching stage rather than the cataloguing stage. Uniform titles will be needed as one of the linking mechanisms. The value of ISBD needs to be justified. Issues connected with the Internet and search engines are explored. A scenario for the Catalogue 2000 is given that envisions the cataloguers' aims being the inclusion of library catalogue material that is relevant but not necessarily in the library.

Abstract

At the beginning of the eighties the Library Establishment was engaged in a battle with the heretics over the implementation of AACR2. Those who were in favour of the new code wanted immediate implementation of AACR2. The critics, however, wanted delay, arguing that the disruption of implementation would damage library services and be very expensive. They also argued that delay would mean that progress in automation would make implementation easier in a few years time. No one would claim that the early implementation was a complete disaster. Few, however, could pretend that it made a dramatic impact in improving the quality of our catalogues while some would argue that it had made them worse. Since there are no figures for the cost of the implementation the critics are justified in arguing that the Library of Congress and the British Library paid a heavy price in order to ensure that implementation took place. Today we face a new challenge. Bibliographic control is at a stage of development which could lead to a dramatic improvement in its scope and effectiveness. This will not be done by producing another edition of AACR. Nor will it be done by maintaining that the main entry is essential. Horizons need to be widened. Principles need to be reexamined. New methods need to be considered and the whole exercise must be linked to automation and not the traditional methods of the past. This paper is an attempt to look at some of the possibilities.

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.
