Peter in his bookmarks points to a description of by Swiss blogger Lukas Mathis. lets you make a list of authors you are interested in, and then provides you with a RSS feed that will alert you to new books published by those authors. It uses the Google Books API. It’s a clever small personal tool that Lukas Mathis built. I like it. I’ve added a handful of authors from the top of my head, and subscribed to the resulting RSS feed. I also added a monthly reminder to my task list to add or remove authors from the list.
