This collection documents Dr. Gilb’s work at the University of California-Berkeley from 1954 to 1962, when she developed the Regional Cultural History Project (the forerunner of the Regional Oral History Office) and conducted oral histories for the Institute of Industrial Relations. The collection documents early methodology for conducting oral histories and twenty-four completed interviews of union members, employers, and professionals in the labor relations field. The histories describe the daily work of typographers, teamsters and retail clerks from the early 1900s to the 1950s, and is an excellent history of San Francisco Bay Area labor relations during that period.
