Royalty Books

http://www.royalty.nu/royal/books.html

Royalty books may be a very narrow sub-genre, but I just stumbled across this awesome site for all  things royalty (including books) and thought I'd share. Along with pages on the history of various monarchies and the latest news on the lives of monarchs, the books page lists recently published books on royalty around the world as well as book lists for specific countries. So if you are ever confronted with a customer (like I was today) looking for a mysteriously untitled book about the British monarchy, this might be a good place to look!
