This collection contains dairies, stereoscopic photographs, correspondence, clippings, bulletins, pamphlets, and publications relating to the work and ministry of Newton Tennis Gottschall. One of the diaries, written while in Indonesia, is from Charlotte Agnes Swank Gottschall.

This collection contains seven folders of stereoscopic photographs that were used primarily for Sunday School lessons in the early 20th century. A portion of the photographs are stamped with the corresponding age level lesson and date. With one exception, all of the photographs illustrate Bible lands with appropriate notations. There is one slide that documents a meeting of the Methodist Episcopal Church's bishops at an unknown location. Underwood and Underwood published most of the slides though there are a few from H. C. White Company.
