If you love science fiction like I do, and you are a dedicated ebook fan, as I am, you should stop by the Baen Free Library. Baen is a great publisher of sci-fi, especially the 1622 series and Honor Harrington, and they have gone out of their way to present ebook versions of some of their greatest hits absolutely free. Stop by and check them out with your new nook, Kindle, or iPad, and if you haven’t tried the two titles I mentioned above–do.

Keep in mind, Wes, that the Baen Free Library may be changing soon: http://www.mobileread.com/forums/showthread.php?t=198220&highlight=baen
I hadn’t realized that Moe, until you pointed it out. And thanks for the link. I’m surprised that it lasted this long in many ways. I think the old philosophy of giving away ebooks as a way to increase your paper book sales is well past.
