The downloadable bundle is provided to you in three DRM*-free file formats: .PDF .ePub .prc
You can view them on the devices of your choice.
.PDF — The PDF format is a widely supported standard, and is a faithful representation of the printed book. Whenever possible, our PDFs also include navigation bookmarks and live hyperlinks.
.ePub — One way to describe ePub is “mp3 for books.” Instead of each Ebook software and device maker using their own format, the ePub standard is meant to give readers, publishers, and device makers a single format for Ebooks — one that includes many of the same features we’re all familiar with on the web, like reflowable text and hyperlinking.
.prc — A format compatible with all Kindle devices and with Kindle readers/apps on many other devices.
* DRM – Digital Rights Management (restrictions to limit sharing of ebooks).
