    Abstract
    Describes the European Commission's OPAC Network in Europe (ONE) project which attempts to make it simpler to search a number of major European OPACs crossing all frontiers via online interface. Explains how this is done and the British Library's involvement in it, assessment of the project and plans for the future

    Abstract
    Effective resourcesharing presupposes an infrastructure which permits users to locate materials of interest in both print and electronic formats. 2 approaches for providing this are union catalogues and Z39.50 based distributed search systems and computer to computer information retrieval protocols. The advantages and limitations of each approach are considered, paying particular attention to a relaistic assessment of Z39.50 implementations. Argues that the union catalogue is far from obsolete and the 2 approaches should be considered complementary rather than competitive. Technologies to create links between the bibliographic apparatus of catalogues and abstracting and indexing databases and primary content in electronic form, such as the new Serial Item and Contribution Identifier (SICI) standard are also discussed as key elements in the infrastructure to support resource sharing
