Series 1: Correspondence, 1947 -- 1974
This series is open for research.
6 folders
This series contains correspondence about the studies as well as information about the donation of the collection to the Missionary Research Library. Thayer was a firm believer that the Missionary Research Library was important, and had used the resources for his own PhD thesis published in 1951. Thayer offered copies and details on the studied missionaries and their results to the Boards of Missionary Organizations and this series also contains that correspondence.
This series is arranged roughly chronologically.
