The Illustrated Section
The Illustrated Section is the brain child of illustrator, Dani Jones. It's a place for creators of digital picture books, graphic novels, and illustration advice books to gather and sell their wares - and some pretty impressive wares they are!
Dani's series "My Sister the Freak" is so well done, and Thomas James' (of Escape from Illustration Island) "15 Steps to Freelance Illustration" is a great resource for those trying to break into the business.
All the files are in .pdf format, so if you can access the internet on your reading device, you can download one of these great books. Check it out!
