This collection contains many of Drury's publications: his biography of Otterbein, as well as a number of pamphlets; photographs; Drury's letters that he authored, and letters he received; letters or collections of old works that Drury kept for himself.

Among his letters, most of them are demonstrative of the kind of inquiry he was making into Otterbein and the history of the United Brethren Church in Christ. For the kind of histories that Drury was writing, he was meticulous about dates and the need to keep them straight in order to construct a coherent history. Much of his personal notes contain lists of dates, where it is clear he was hovering over the page attempting to connect disperate material or events. The largest collection of letters comes between 1883-1884, where Drury was ostensibly doing the bulk of his historical writing and attempting to contact any living witnesses available.

The photographs of this collection are largely unmarked, though there is at least one picture of A.W. Drury that is identified.

Drury's interest in Christian apologetics eventually led to an interest in things secular, as he later developed an interest in behavioral patters and their relation to religion; this led to his interest in William James, and the pamphlet he wrote on Psychology of Religion.

This collection includes personal papers, photographs, and personal items from the life and work of the Draper family. There are four photograph albums that have pictures of the Draper children, places the family lived in Asia, other missionary staff workers, and their students. There are photographs of students in China and Malaysia that show the schools and classes Charles Draper taught science and Mary Ethel Draper taught English. Also included are Charles E. Draper's higher education papers from when he attended Purdue University.

The Mellony Turner papers primarily documents her life as a missionary in Bulgaria. There is a number of records on the American School for Girls in Lovetch, consisting of photographs, textbooks, yearbooks, and financial records. Turner's notebooks and lecture notes are included in the collection. It should be noted that there is a single folder containing information on closing the school. Turner kept diaries during her tenure in Bulgaria as well extensive correspondence. There are general images in both photograph and slide format ranging from the royal family of Bulgaria to her own family in the United States. Turner has a copy of a sermon by Bishop Burt; the bishop who had established the Bulgarian mission at the beginning of the twentieth century. Clippings and other types of publications reflect Bulgarian life and politics. There are eight lectures and a sermon written by Turner. Artifacts are personal in nature, reflecting the clothing and accessories of mid-twentieth century Bulgarian dress. There is a pot in the artifact series as well.

The other series within the collection reflects Turner's immediate family. The few records relating to her parents deal with their will and a folder of letters. Mellony's brother, Ewart Turner's three folders are related to his spying for the United States War Department during the World War II. Though he was ministering to a church in the United States during the war, Ewart was familiar with German communities in Europe and South America. The War Department had Turner collect information on Germans, in the U.S., who were thought to be a threat to national security during the war. This information is elucidated in a correspondence folder.
