From OCLC:
The University of Washington Libraries is the first to pilot WorldCat Local, a new service that builds on WorldCat.org to allow Web access to the world’s richest database for discovery of materials held in libraries. The goal of the pilot is to provide users with a single search and request service that covers the University of Washington Libraries, Summit libraries (most academic libraries in Washington and Oregon), WorldCat and a selection of article citations–all through one catalog.
