Notes:

• EPUB or PDF books with an ACSM file extension are protected by Digital Rights Management (DRM). DRM protects books from unauthorized copying, and is often used by libraries, publishers, and booksellers.
• Your eReader supports Adobe DRM and Social DRM.
• If you download a book that is protected with Adobe DRM, you will need to use Adobe Digital Editions to put it on your eReader. You can read social DRM files without using ADE.
• ADE is only compatible with Kobo eReaders and will not work with your Kobo App.
