The second floor is the research floor, filled with non-circulating materials. There is a good amount of seating, with electrical plugs for computer chargers. There are two copy machines (15¢ a copy). There are two microfilm machines, though I did not try them today. There are about five rows of books that would be of interest to genealogy researchers. The collection includes a few Atlanta & Atlanta Suburb City Directories for the 1960s, GA County Histories, books of Vital Records for some counties, Census Indices, DAR books and more.
Some records that I found useful were "The Hart of Georgia: A History of Hart County" and the Atlanta Suburban Directories. I was really hoping to find Cobb County, Georgia marriage records, but the ones I found were from too early of a time period. I'm hoping to go back soon to look at the Hart County book again - it was thick and I hardly got started looking at it.
