    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
    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 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
