A lot of counties do not offer plat map books, but if you go to your county Property Appraiser's office you should be able to get the contiguous landowners names and addresses with a map. If the books are available in your county I've seen a lot of different venues to buy them, from banks, NRCS OFfice to the Chamber of Commerce. Your Property Appraiser's office should know if they are vailable in your county.
