Clumping in the UK: towards virtual union catalogues

Following the initial success of the eLib Programme for Higher Education libraries in the UK, the most recent phase of funding has been directed at hybrid library and clump projects. A clump is an aggregation of catalogues which may be physical ‐ a traditional union catalogue ‐ or virtual, being created at the time of searching. The most common protocol in use in clumps is Z39.50 which offers opportunities for creating gateways to a range of catalogues, thus allowing simultaneous parallel searching. Four clump projects have been approved by eLib and started work in January 1998: CAIRNS ‐ Co‐operative Academic Information Retrieval Network for Scotland; M25 Link: Access to London Libraries; Music Libraries Online (a geographically split subject clump); RIDING: Z39.50 Gateway to Yorkshire Libraries.
