I have looked for a way to get alerted about new releases from my favorite authors for a long time. I think Amazon used to support this in the past but they no longer do. Barnes and Noble has writer alerts for only a small list of authors. This is such an obvious feature for a bibliophile that I do not understand why nobody supports it. I was about to write my own code but luckily ran into www.authoralerts.com first. Highly recommended.
