Saw this is Waterstones and thought about it for a week, because it cost £10, but in the end couldn't resist because it looks like such a great way to keep a little catalogue that makes a great deal of difference if you read a lot of books that you get from the library and don't actually have them physically around. It resembles a n A-Z address book but instead of name and address it has space for author, title, date and comments.
