Yeah, I wish I'd discovered it before purchasing a bunch of Honor Harrington books during a Fictionwise sale a couple months ago. The entire series is available for free download, except the most current volume appears to be an advance reader copy, so I went ahead and purchased that one, thinking I'd get it in a final edited form that way. But on the other hand, I've gotten so many free ebooks from Baen that it's nice to give them some money
Anyway, drop by there and check it out. Loads of stuff that isn't in the free library:
