Greetings, All. Though I have tossed out a few comments, I have very little experience with the BP (but am finding it is great) so have a question for all the veteran users out there: I have seen reference to Audible.com and Bookshare as sources for downloadable books. Are there any other commercial and noncommercial sources (such as eReader and Baen, for example) that you have found to have lots of material and are fairly easy to use? Thanks in advance for any assistance you can provide. Michael
