I got a book from barns %26amp; noble online but I don't know if I can download it to my sony ereader? Is this possible? If so could you tell me how?|||Nope. It's not possible.
Even though they use the same file type, the licensing is different.
You will have to read that one one you computer and buy any new books from Sony or any independent ebook store on the web.
Supposedly you can buy from Borders as well, but I suggest trying a free book to see if you can get it to work before investing any money (another asker is having problems)|||no... haha based on that ^ love ya haha
