For the past 5 years my wife and I have been travelling the western states. We avoid cities but do stop into smaller towns to provision and explore. It has been heartening to see so many small to mid sized towns still have good used book stores. They are not hip or ironic or kitschy just a decent store stocked with old books at good prices. Often they will have a section devoted to local history. Las Cruces NW for instance has an enormous used book store that looks prosperous. We always go in and stock up on inexpensive reading material.
