Thanks for the suggestions! I wanted to pass one that I heard about over at goodreads. it is called http://www.crapimissedit.com/
and it lets you set an email address to be notified at when a particular author has new book info on amazon.com. It can also be configured to notify you about concerts, tv shows, ect. I am not sure how well it works yet or if it can tell the difference between a pre-order and an actual release...but it is a cool concept.
