The Open Library Network (OBN) is intended to connect national and local university library systems in the Netherlands. OBN integrates existing automated library systems and procedures and brings services like catalog searching and document delivery to the desk of the library user. Project results can be grouped into four categories: (1) the new system; (2) the new online catalog; (3) the national network of online public access catalogs; and (4) the central gateway functions. The project is being carried out by the Pica Center for Library Automation. In the last few years the SURFnet network has provided advanced network infrastructure in the Netherlands. The OBN combines the efforts of the Pica Center with those of SURFnet. With technically advanced network services, the OBN will set the library user in the center of services with seamless access to catalogs and databases. Improvement and introduction of new services are planned, based on user evaluation. The new activities and services should, within the next few years, establish a system for fast mutual document delivery. Eight figures and four tables illustrate network operation and features. (SLD)
