 I think another important way in which a fair use code matters is because it gives us the courage to take the kinds of risks that we should take. At Berkeley, we recently discovered that we had a marvelous collection of 19th century and 20th century photographs of the landscape of California. Frankly, there's a lot of trees and a lot of brush. And these were photographs that were taken by Berkeley faculty over that period of time. The professors in most cases were dead. Their family was hard to track down. No one knew if we had missed someone who might have wanted to hang on to the rights to those photographs. Of course, there was no paper trail of permissions or anything else. So we used the fair use code to kind of go through the steps of thinking out how much effort we should make and then should we go live. And today, you can see all the trees and brush from California that you'd ever want to see taken by members of our community. And I'm making light of it, but it's extremely important to people studying the environment of California. And from the point of view of just being a tourist, places you've camped or places you've been, if you'd like to see what the landscape looked like 50, 60 and more years ago, come online and see it.
