The Chicora Foundation from South Carolina has published a number of readable research reports that should appeal to those interested in the intersection of archaeology and Civil War history. On a whim, I checked out:
Research Series 59. A Survey of Civil War Fortifications in Charleston, Beaufort, Berkeley, Hampton, and Jasper Counties, South Carolina. 2000. Michael Trinkley and Sarah Fick. ISBN 1-58317-054-5.
This particular volume contains a number of maps, both overlays and large pull outs that trace and mark the sites under study. Photographs, tables, and drawings are also included. It appears to be quite useful for Civil War research, but does read like a government report so don't expect a pleasurable narrative or much background information.
I wonder how many other states have similar offerings.
