    Abstract
    The State Library of Iowa, USA, received a Higher Education Act title II grant from the US Dept. of Education in 1994 to create a demonstration project of new library information technologies. Describes 2 interlinked components of the project: Web-based union catalogue development and statewide deployment of the ANSI/NISO Z39.50 standard for database search and retrieval. Z39.50 was chosen because of its ability to searching multiple remote databases in a single session and its common interface across a variety of implementations. Use of a distributed Z39.50 search makes the need for maintaining large union catalogues unnecessary

    Abstract
    This paper proposes the integration of tools to provide unified access to remote and heterogeneous archives, the contents of which can be grouped under the same subject, and which have been integrated to allow the user to navigate and conduct thematic searches. The information sources are locally frequently modified, added to, and removed, therefore attention has been paid to the permanence of their references. Source interoperability is supported at language, protocol and schema levels. The architecture is based on a new common schema of the archives which is defined in new representation and query languages on the basis of an ontology to avoid misunderstanding and ambiguity.
