Columbia Center for Oral History was founded in 1948 as a center for conducting biographical interviews on political history. CCOH is renowned both for the breadth of its holdings and its vision for developing oral history as a field of study and practice. Scholars consistently turn to CCOH not only for its collections, but for guidance in how to teach and practice oral history. Increasingly, through the development of educational programs and innovative research projects, CCOH serves as a laboratory for the continual development of oral history methodologies across the disciplines. In turn, students and scholars trained by CCOH produce new scholarship and create new interviews, enriching the archive and expanding the breadth of oral history as a field of study and practice. CCOH is home for over 20,000 hours of recorded conversations, and over 8,000 interviews conducted on almost every subject in American history, in addition to the history of science, medicine, philanthropy, public health, and the arts.
