The second major revision of the OPAC module of BLS (the BLCMP stand‐alone library system) allows libraries to offer users different views of the catalogue files. Record selection software allows sub‐set catalogues to be constructed according to library defined criteria, such as subject, physical format, location or language of publication. These views of the catalogue can then be offered to users of OPAC, where the record retrieval and display facilities have been enhanced to allow each view to be optimised according to its contents; for instance individual libraries can now define various algorithms for the generation of suitable acronym keys for particular sub‐set catalogues.
