UC librarians Sherri Berger (CDL), Lynn Jones (UCB) and Ellen Meltzer (CDL) have contributed a chapter to Past or Portal? Enhancing Undergraduate Learning through Special Collections and Archives, edited by Eleanor Mitchell, Peggy Seiden, and Suzy Taraba. Their chapter, also deposited in the open access eScholarship Repository, is entitled “’The Links in the Chain’: Connecting Undergraduates with Primary Source Materials at the University of California”. It describes undergraduate usage of archive and special collections mainly at UC Berkeley’s Bancroft Library, often using OAC for discovery. The article also explores instruction in a lower division gateway history class and the UC Berkeley Prize for Undergraduate Research as significant factors in encouraging undergraduate usage of special collections.
