This collection contains interview transcripts, published and unpublished reports, research notes, working papers, maps, clippings, correspondence, memoranda, and statistical data gathered by Joseph M. Carrier primarily while he was employed as a Rand Corporation counterinsurgency specialist with the Chieu Hoi Program in Vietnam. The bulk of the materials pertains to the Chieu Hoi Program, which was operated by the Republic of Vietnam from 1963 to 1973 to encourage civilian and military defections from the communist-controlled South. The collection contains materials documenting the administration of the Chieu Hoi program in addition to transcripts of interviews conducted with defectors (or "ralliers"), prisoners of war, and refugees. English and Vietnamese interview notes, translated Viet Minh (or "Viet Cong") documents, and preliminary interrogation reports are also included. The collection also contains administrative materials produced by the Rand Corporation, the United States government, Republic of Vietnam government, the National Academy of Sciences, and other agencies documenting such topics as Viet Cong and U.S. military activities; counterinsurgency movements; the use of herbicides and their toxicological and environmental effects; and Vietnamese socio-economic conditions, social history, politics, and demographics. A small group of files contain Carrier's research materials for the San Francisco Center for Southeast Asian Refugee Resettlement's 1991 study of AIDS knowledge, attitudes, beliefs and behaviors in San Francisco Southeast Asian communities. The majority of materials are in English. Some materials are in Vietnamese.
