This is something I would like very much as well. Currently I do it manually, by periodically checking if there are any new books out from my favourite authors. This is of course far from perfect, as I tend to miss one every now and then, and it also takes time. Anyone know of a service that does this already?

> enter a list of authors I like and get notified when a new title is available by any of them.

I must confess you are not the first person to suggest this. I don't plan to implement it right away, but as the service grows, I'd like to add an "alert" component to it.
