On the back of my Smithsonian, there was a great ad (November 2010) edition. It's for Domtar, and their website is Paperbecause.com. I went exploring, and they have a very nice website too.

The reminder is that the Gutenberg Bible was printed in the 1450s, and there are still 21 copies around today.

It was a nice reminder about the longevity of paper books.
