Over the years, donor Wade Hall has collected hundreds of photographs, many of unknown provenance, reflecting everyday life and activities in the 20th century.

Before the Internet, people had to work at lot harder to find out about their family history!
Pauline Jones Gandrud was known all over the South as a woman with a lot of experience doing genealogical research. People would write to her with what they knew of their family tree, and she would go to local archives and copy out information for them -- birth, marriage, and death records; deeds, wills, and other legal papers; and anything else of note.
Meticulously organized, Pauline maintained massive records on hundreds of families, and after she died, her family donated them all to the W. S. Hoole Special Collections Library.
The process for digitizing these records is long and ongoing, but you can see what has been completed at any given point by looking at the Gandrud papers online finding aid.
