Feedbooks: Free eBooks for Mobile Devices (including the Kindle)

Feedbooks.com takes public domain books and provides them for free for a variety of electronic book readers (including Windows Mobile mobile phones and the Kindle). Windows Mobile smartphones can use either the Mobipocket or ePub formats provided by Feedbooks. I've installed Mobipocket (also free) on a Windows Mobile Professional Edition (Pocket PC) device and will be looking at it closer on my MobileViews.com blog.
