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.
