Leedy was an avid collector of church related information so that the topical landscape of this collection is broad enough to cover information ranging from local church ministries and histories to denominational theological beliefs and social concerns. Most of the paper records center on church work in the Ohio region though not to the exclusion of other geographic areas within the continental United States and Germany. All in all this collection provides a nice overview of the diversified life within the Evangelical tradition and is an excellent resource for those who wish to understand more fully the Evangelical Church's historical influence within the ongoing traditions of United Methodism.

Sauer's correspondence, and the manuscript and supporting documents for his unpublished "Methodists in Korea," make up the bulk of the collection.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.
