CORC?the Cooperative Online Research Cataloging project?is a collaborative research initiative of the OCLC Office of Research and about 150 participating institutions, including Cornell. It provides Web-accessible shared databases and automated tools to help libraries manage and provide intellectual access to the massive amount of material becoming available on the Web. The "CORC at Cornell" project was undertaken by a small, cross-functional research team of seven people. We worked on the project from mid-May to mid-November 1999. In the approximately 400 hours we spent on the project, we: (1) selected and cataloged about 120 new resources for the library catalog and Gateway; (2) experimented with a new workflow in which selectors, reference staff, and catalogers collaborated to create metadata; (3) gained practical experience with Dublin Core; (4) explored the features of CORC for creating subject guides (a.k.a. pathfinders); (5) evaluated the functions and features of the CORC system; (6) enhanced our abilities to select, manage and control electronic resources for the library.
