The diaries of Sally Independence Foster span the years 1861 through 1887. They include a period while she was living in the school's Rogers Hall, which was once occupied by soldiers including Confederate Gen. Nathan Bedford Forrest.
Rogers Hall became part of the campus at Florence in 1948.
The woman's great granddaughter, Flora Speed of Marietta, Ga., says Foster wrote about everyday life and the feelings of a teenager living during the war.
The diaries were donated to the university by Speed and other relatives of Foster. They will become part of the university archives.
