You probably have heard that at the Historic Courthouse, we are currently showing historic photographs relating to Haralson County which are part of the "Vanishing Georgia" collection, using the "card catalog" PC in the first floor corridor. The collection is described online here.
Today I ran across an interesting Website that hosts what it calls "faces and places of the past". Find it here at familyoldphotos.com. I have not made an effort to look for comparable Web sites and so have no opinion on its comparative merits. It claims to host over 17,000 photos so far.
My encounter with this Web site arose out of interest in a particular county in Pennsylvania. The page associated with Pennsylvania includes a drop-down menu listing many (or all?) of the counties of that state. Sadly, the corresponding Georgia page does not include such a menu, presumably for want of photos. For what it is worth, find the Georgia page here.
