At any given time it seems like I'm reading 5+ series book by book as they are released, and I have tons of trouble keeping up with what comes out when.

Amazon and Audible wishlists help me keep track of books I want to read, but they don't notify me when something new is published or a publication date has been announced.

Some friends just 'don't read series that aren't finished', but I'm just not that kind of person.

Anyone have any tips on getting email or other notifications when books are published, short of subscribing to all of the individual blogs of all the writers that I'm mid-series on?

EDIT: please excuse the aberrant apostrophe.
