Opening DRM-protected Files
DRM stands for Digital Rights Management. DRM software protects books from being illegally copied, sold, or distrib-
uted.
Your NOOK and the Barnes & Noble website automatically make sure that when you buy and download a
NOOKbook, the NOOKbook recognizes you as its legitimate owner and presents its contents for you to read on
your NOOK.
In some rare cases, you might need to unlock a book or periodical that you have bought from Barnes & Noble. In this
case, you'll need to enter the following information to unlock the book or periodical:
• Your name
• Your email address (the address associated with your BN.com account when you purchased the book or periodi-
cal)
• Your credit card number (the number of the card you used to purchase the book or periodical)
