Query: A Great Sourcebook

I am a documentary photographer, specializing in endangered historic buildings. Having explored New England for a number of years, I am in the process of moving to Charlotte, NC.This book will be the starting point for my work in the south. It is well organized, with sites listed by counties and there are clear maps. The book is detailed, with a good basic history of the area at the beginning. A particularly nice feature is the notation as to whether a site is private, open to the public or may just be viewed from the highway. I also own the Guide to the Historic Architecture of Western North Carolina and find it equally valuable.
