Alan,
I believe that you could order them on-line, possibly from books a million, but I doubt you could find either book in Florida and it would be hit or miss to an individual store in Georgia. If you can't find one, I certainly could sell you one directly (my book) if you were interested. My book sells for $20 + shipping. One of the wholesalers like Amazon.com, walmart.com, may have them cheaper at discounted prices to save you some money. As far as Roddy's book, I picked my copy up at a convention and am sure where to order it, but would certainly look at the same wholesalers. Best wishes to you as you research Georgia's Confederate past.
