What's inside a county plat book
Private publishers compile plat books from county records, so a county edition is a snapshot of who owned land near Leighton the year it was printed. Don't confuse it with a subdivision plat on file for lots in Eddyville; that recorded plat is a legal document, while the atlas is a reference.
