Everyone (should) know about the Baen Free Library http://www.baen.com/library/ a GREAT place for books from a selection of damn good Sci fi/fantasy authors.
But there's also http://baencd.thefifthimperium.com/ the Baen Free Cd's. Apparantly sold with certain Baen books, and given free licence to be copied over the internet, they contain a fair number of pretty good books not found in the library. I've never seen it mentioned before.
I recommend John Ringo's Ghost, from my preliminary reading.
Here's http://www.allensmith.net/SciFi/BaenFree.htm a list of the books contained in both the CD's and the Library... it's color coded even :D
Neat stuff. Thanks for sharing that link.
