Less than one linear foot of 14 reel-to-reel audiotapes, one book, one manuscript, and nine volumes of the Ethnographic Study Series: Selected Groups in the Republic of Vietnam document various ethnic groups in the Republic of Vietnam and Dr. John Campbell's tour of duty as a Psychological Operations Advisor to five different provinces of the Republic of Vietnam. The manuscript, entitled 'Are we Winning? Are They Winning? A Civilian Advisor's Reflections on Wartime Vietnam' was written by Campbell in 2002. The audio tapes are from the Vietnam Conflict-era and contain 'easy listening' music and Psychological Warfare messages.
