That bright blue ball rising over the moon's surface, containing everything we hold dear - the laughter of children, a quiet sunset, all the hopes and dreams of posterity - that's what's at stake. That's what we're fighting for. And if we remember that, I'm absolutely sure we'll succeed.

More than a building that houses books and data, the library represents a window to a larger world, the place where we've always come to discover big ideas and profound concepts that help move the American story forward and the human story forward.

I think the American people recognize is after a decade of war it's time to do some nation building here at home.
