What is DRM?

DRM stands for Digital Rights Management, which is technology that is intended to prevent unauthorised access to, distribution of, or copying of your NOOK Book. If you choose to have DRM applied to your NOOK Book, we will use this technology. This choice can only be made once per Project and cannot be changed once selected. Please read our Terms & Conditions for more information on our obligations regarding DRM. To learn more about DRM, visit the Wikipedia entry.
