Giftodd--sorry, the first time I posted I had overlooked that you were in Australia. So forget about the "History of US" unless you for some reason care about US history. However, I forgot to mention that I have found some good recommendations on Amazon (sorry--also the US site, but I'm sure you could find them there and then buy elsewhere if necessary) and also on the Hoagie's Gifted site, in case you haven't heard of it (it'll come right up if you Google).
