How do I get permission to copy to my Nook?

[dennisk40194363]

I can successfully download a book from the library to my Windows based computer.  However, when I try to transfer the book to my Nook I get the message "CE_COPY_NOT_ALLOWED_ No permission to copy the book".  How do I get permission to copy the book?
