The Appalachian Preaching Mission Records, held by the Archives of Appalachia at East Tennessee State University, includes brochures, correspondence, financial statements, memoranda, and minutes for city and area committee meetings, miscellaneous items connected with each year's mission (e.g. programs, photographs, ribbons, schedules), and recordings of Mission speakers. There also is a brief history of Johnson City's participation in the Mission and a brochure file which covers the years 1954 to 1979. Few recordings exist for the years 1971 to 1974. Many of the tapes dated after 1974 are untitled.

The current digital collection includes audio recordings of ca. 365 sermons and worship services along with one undated three-minute, silent moving image recording.
