PICA and developments in library networking in the Netherlands

Abstract
PICA, founded in 1969, provides services directly to about 500 libraries and indirectly to over 1.600 libraries. These services comprise central services (a shared cataloguing service, a union catalogie with interloans facilities, access to centrally stored reference databases) and services concerned with the development and exploitation of local library systems. The future strategy of PICA assuems the need to expand into other countries and a start has been made with the German speaking parts of Europe
