Baen has been doing this for quite a while, but the population of eBook reading devices is now larger, so a reminder is in order.
Introducing the Baen Free Library
by Eric Flint
Baen Books is now making available — for free — a number of its titles in electronic format. We're calling it the Baen Free Library. Anyone who wishes can read these titles online — no conditions, no strings attached. (Later we may ask for an extremely simple, name & email only, registration.) Or, if you prefer, you can download the books in one of several formats. Again, with no conditions or strings attached. (URLs to sites which offer the readers for these format are also listed.)
These are the file formats available:
* Ebookwise/Rocket Format
* Mobipocket/Palm/Kindle Format
* Microsoft Reader Format
* Sony Digital Reader Format
* RTF Format
