I belong to a group of mass market writers who have posted their own backlist as e-books. I've posted my award winning Dushau trilogy to Kindle, but Wildside's Borgo imprint is doing my Sime~Gen novels, and already has Molt Brother and City of a Million legends on Kindle and other e-book formats.
Over 70 authors belong to this Group - called Backlist Ebooks. Here are a few who have blogs you can learn from.
