There's been a note posted Here...

"When we do go live on third party platforms (and it is a when now, not an if), we'll have to make some changes to the Baen Free Library. I suggest everyone backup whatever they've got now and spread the word, as there will be titles we have to take down. We'll be keeping as many as possible and will continue adding new titles as practical."

System conversions always have risk, even when you try to minimize it, back up your files, folks.

So not only back your books, (including purchases), but get the freebies while they're still free.

Scifi and Fantasy. Some Oldies but Goodies I hear.
