From the NYT:
"The advertisement for the Nook says that consumers will be able to “access over one million e-books, newspapers and magazines.” About 500,000 of the books available at BN.com can be downloaded free, through an agreement with Google to provide electronic versions of public domain books that Google has scanned from university libraries. These editions are currently not available on the Kindle."
