The Kindle books that you buy from Amazon are DRM-protected meaning you can only read them on a Kindle Reader or an official Kindle App. It is not possible to read your purchased Kindle books in other ebook readers like the Nook.

Amazon has these DRM based copy-protection measures in place to protect Kindle ebooks against online piracy but, as a consumer, the DRM scheme does limit your options.

For instance, you cannot create backups of Kindle ebooks that you already own and second, you cannot convert DRM protected books into other ebook formats like EPUB or PDF that can be read in other non-Amazon apps.
