As the IEEE digitizes its journals, librarians at two University of California (UC) campuses undertook a project to identify a single best possible copy to preserve in a regional shared storage facility. They describe the process: identifying who owned the most complete runs of each title,the standards they developed to validate completeness and acceptable condition, coordination among all the parties involved, communication with additional campuses as issues arose, cataloging challenges, cost determination, staffing used, space saved, and lessons learned. The methods developed for this pilot project will serve as a model for future endeavors involvingmultiple institutions that want to collaborate efficiently.
