I make plat books and other maps for the Federal and State Govt. I would say either get a plat book from the courthouse or city hall of the county you want to hunt in or go directly to the County Assessor. The Assessor would be the best b/c sometimes the plat books are not always correct. As soon as a plat book is finished the next day they are wrong due to the buying and selling of land, split parcels, and straight transfers.
