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.
