Tina, I lifted this from another list:
Just so you know, DLG (Digital Library of Georgia) has Sanborn maps online up to 1923 for most places in Georgia
The Digital Library of Georgia and its partners have recently released several new digital collections as part of the
Georgia HomePLACE initiative that may be of interest to SGA members:
Milledgeville Historic Newspapers Archive, 1808-1920
Milledgeville papers Columbus Enquirer, 1828-1890
Columbus GA paper Macon Telegraph, 1826-1908
Macon Telegraph (These newspaper databases require a one-time free plug-in download to view images.)
Just to get you started. There are photograph collections too.
