The Walter Russell Lambuth collection reflects the Bishop's activities outside the United States in a series of manuscripts, articles and letters. There is one typed manuscript of his book, Medical Missions: The Twofold Task. There is a good chance that most, if not all, of the other typed manuscript articles of Lambuth's trips around the world were published by the Southern Methodist Church in their various periodicals. The correspondence is addressed to family, friends, colleagues and associated groups. Clippings are either death notices and/or tributes for both Lambuth and his wife.

This collection contains mostly administrative records from Williams' work in missions administration. Included are Williams' reports on his trips overseas; personnel application procedures and personnel development procedures; papers and reports by other authors on missiology and missions theory; a history of the Joint Committee on Missionary Personnel: clippings, books, pamphlets, and reports on several geographic regions, especially China.
