I collect the "Images of America" series and I just picked up "Remembering Mississippi's Confederates" 2012. I was really impressed with this one because it complements "Portraits of Conflict...Mississippi in the Civil War"

And for those looking for documentation on Black Confederates, it has a section on the Black Confederate pensioners living at the Confederate Home Beauvoir in Biloxi.
