Thanks to Jennifer at Jean Little Library for telling me about Author Alerts. You can sign up to get either e mails or RSS feed on what ten authors are doing. I signed up for Erin Hunter, Tim Green, Mike Lupica and some more because it seems like I am always missing a book from them. Here's the fun part, though, from the Author Alerts site:
"We are trying to get the word out about our site. Simply blog, tweet, post something on facebook or tell your real life friends about us, then let us know by e-mailing us at email@example.com and we will increase your alert limit to 100!"
Can I use updates on 100 authors? Unfortunately, yes!
