I've mentioned Feedbooks http://www.feedbooks.com/ before. It is a great source for free ebooks. As I click over today, I see the four featured books are Moonfleet by J. Meade Faulkner, Uncle Tom's Cabin by Harriet Beecher Stowe, War of the Worlds by H. G. Wells, and On the Origin of the Species by Charles Darwin. Pretty cool, huh? You can of course find tens of thousands of other books on the site as well. But if you click on one of these titles, you will be given the choice of downloading them in one of six different formats-- epub, Mobipocket/Kindle, PDF, SonyReader, iLiad, Custom PDF. Now the Sony Reader will read the epub, and both types of pdfs, but if you have one, you would naturally click on the SonyReader choice. This in fact does not give you a native Sony file. It gives you a pdf formatted for the Sony Reader. This is fine, and it works great, but by using Calibre (see yesterday's post) you can convert the file into a native Sony lrf.
