What if EPM doesn't sell an ebook edition specifically for my e-reader?

You have a couple of options. The iPad, Kobo, and Nook editions of the ebook are in the epub format. Although each of these editions are slightly tweaked for the particular e-readers, epub is a generally accepted file type for all e-readers except Kindle. So if we don’t sell an ebook edition for your e-reader, you may purchase one of the epub versions (iPad, Kobo, or Nook) and it will work on your e-reader. Another option is to purchase the PDF edition of the ebook, as all e-readers support PDFs. You can also read PDFs on your computer.
