I'm looking for a service that will notify me via email when an author I like has a new book out. Ideally this would be hooked into Amazon since I get all my books through there but I don't think they have this. Right now I accomplish this by continually polling Amazon's author pages or by signing up to the individual author's email newsletters.
If this doesn't already exist, any idea where I might get the data to build something simple? Some sort of publisher/bookseller data dump, or, even better, API service... I doubt Amazon would appreciate me scraping their site for the info.
