- Adaptable Network Cooperate Catalog for Complex Information Objects. From Single Library to a Consortium: Sharing the Management and Distribution of Information Resources. Morag, Azriel Cataloging Computer Mediated Communication Computer Networks Computer System Design Cooperative Programs Foreign Countries Library Catalogs Library Networks Online Catalogs Online Searching Shared Resources and Services Libraries faced with the challenge of cooperative cataloging must maintain a high degree of unification within the library network (consortium) without compromising local libraries' independence. This paper compares a traditional model for cooperative catalogs achieved by means of a Union Catalog that depends entirely on replication of data between the local libraries and the Union catalog, with a more advanced concept, the Virtual Cooperate Catalog (VCC) that includes an engine that enables a unified search and retrieval of records across diverse local library catalogs and systems. The two models are in fact complementary in their achievements. The ALEPH500 library information system contains a special component, the ALEPH-Net proposes a flexible model that can be tuned in order to achieve the best balancing between virtuality and the reality of data: a Network Cooperative Catalog (NCC). The basic conceptual and technological elements that underline the NCC consist of a distributed database design, links to other records, and an "Expand" option. (AEF)
