Straight from my unsorted notes and google searches, hope I get the correct. Like I said it is sometimes hard to get information on DRM at some web sites. No idea if these are any good, I haven't tried them. Unrelated note: I suspect that epub format is better able to represent technical documents, such as bullet points, tables, pictures, etc, then AZW (Kindle's version of Mobipocket with DRM). Or it could just be that Amazon does a really lousy job at translating these documents into Mobipocket format. As in the formatting can be completely stuffed up, images too small and low resolution, etc. The quality of the technical epub books I have seen from Google books - epub with drm - seems to be better then what I have seen from Amazon market, plus (at least with Google), you have access to the original scanned document page. Amazon do have a new file format, KF8, based on HTML5 and CSS3, that maybe might resolve these issues. http://en.wikipedia.org/wiki/Comparison_of_e-book_formats $0 cost or Public domain: http://ebooks.adelaide.edu.au/ http://www.gutenberg.org/wiki/Main_Page http://www.freekindlebooks.org/ http://www.fictionwise.com/ http://gutenberg.net.au/ http://www.baen.com/library/

Not convinced this is the case. There might be issues trying to translate from ePub to Mobipocket format, however I didn't read those comments in detail. Apparently Harry Potter ebooks are somehow water marked, is this a problem for us? http://www.mobileread.com/forums/showthread.php?t=173976 anti-DRM propaganda: http://boingboing.net/2010/01/11/david-pogue-tries-dr.html Last time I search I saw an author that was selling DRM-free ebooks under a name-your-price system. Can't find it right now unfortunately. -- Brian May
