Sauer's correspondence, and the manuscript and supporting documents for his unpublished "Methodists in Korea," make up the bulk of the collection. These materials document Methodist Episcopal mission work during Sauer's tenure in Korea, including the evacuation of missionary personnel in 1940, and their return in 1945. This was a critical transition phase for the Korean Methodist Church (KMC) as they struggled for power and control during the heightened Japanese control over churches in Korea, and then rebuilt after the war. There is also considerable material covering state of missions and the KMC during the invasion of South Korea in 1950. Photographs and publications nicely supplement this part of the collection.

This collection includes personal papers, photographs, and personal items from the life and work of the Draper family. There are four photograph albums that have pictures of the Draper children, places the family lived in Asia, other missionary staff workers, and their students. There are photographs of students in China and Malaysia that show the schools and classes Charles Draper taught science and Mary Ethel Draper taught English. Also included are Charles E. Draper's higher education papers from when he attended Purdue University.

This collection contains photographs, portraits, photograph albums, correspondence, higher education documents and artifacts from the missionary work of the Stahl family members. The numerous photographs and photograph albums contain images of former students including wedding photographs, other missionary workers and various landscapes in China.
