The Oral History of Zhang Xueliang is part of Columbia University’s Chinese oral history project. It is based on the transcripts of a series of 60 interviews with Zhang and his wife (Edith Chao 趙一荻) conducted by two Columbian scholars during 1991-1993. The transcripts and 145 audio cassettes of these interviews are now housed at the Peter H. L. and Edith C. Chang Reading Room in the Columbia University Library. The current edition consists of seven volumes, including six volumes of transcripts carefully checked, edited, and annotated by Chinese scholars and one index and annotation volume. The Oral History not only recounts Zhang’s personal life but also contains his comments on many historical events he personally experienced and influential figures he met.
