Thanks to Paul Biba of Teleread for alerting me to a service I had not heard about previously.
Any New Books? is a service that sends free, weekly emails to subscribers, alerting them to new books being published in the categories that the subscriber selects.
You can select general categories like "fiction" or "nonfiction" or you can choose specific categories like "horror" or "biographies & memoirs." I picked seven specific categories.
You can change your selections at any time.
Give it a try.
