I havn't checked it recently, so what's there is by memory. (and slowly changes) "On Basilisk Station" is the first of a good military SF series (about 30 books now). "Rats, Bats, and Vats" is more humerous, and the one sequel was in the free library too IIRC. Bujold only had a short story there, definatly worth a grab. (also part of a large series, I recomend her SF, her fantasy is ok but not as good.)
For people who have not yet purchased from Baen ebooks, I'll repeat my offer: PM me your email address and I'll put you on the "give a freind a copy" when I purchase a months collection.
If you ask nice at the RTR, (or when you meet me elsewhere) I can give you some more ebooks legally.
