The collection comprises mostly Charles Warren Brewbaker's published works and other writings. The majority of the publications include articles from church-related periodicals. These articles discuss topics such as children’s Sunday School attendance, elderly participation in the church, preaching, and the church’s involvement in society. The unpublished works consist of book manuscripts, sermons, and Sunday School lessons. Given the ambiguous format of the sermons and Sunday School lessons, these often overlap in the collection. There are several miscellaneous items in the collection as well, including Brewbaker’s passport and several photographs.
