National Library of France, by Dominique Perrault I have been to this library, it's beautiful. As I understand it, sometime after it was built it became "clear" that the windows were letting in too much light, damaging the books. They then had wooden panels built for all the windows.
“And that's why books are never going to die. It's impossible. It's the only time we really go into the mind of a stranger, and we find our common humanity doing this. So the book doesn't only belong to the writer, it belongs to the reader as well, and then together you make it what it is.” ― Paul Auster, photo uncredited
