 What they know about copyright and using other people's property to advance knowledge is what they learn in a seminar or learn, you know, from a friend. It's not what somebody tells them in a book or even lectures at them about. So fair use and copyright in general come in as one of these informal ways we regulate ourselves. We stay out of trouble and we're basically fair to other people who've been creative. Having a code of fair use is edging the academy about as far as you should towards an outline of operating procedures. And one of the reasons that we need to do that is because the way we behave at the university can be so local and so driven by these local traditions. So in a library, what people think of as fair use will differ from the folks who handle contemporary videos to the folks who are handling photographs from the early 20th century to the professionals who make decisions about what you can put on an e-reserve from recent writings in the social sciences. And having a code of fair use gives people a common language without trying to, you know, wrap them on the knuckles and tell them exactly what to do. So it's part of the whole culture of persuasion and conversation that makes universities and great libraries run. Some people who are curators or who take care of important collections come to identify very closely with the creative people who are making documentary films or taking photographs or living cartoonists. And they see that these people are really getting the short end of the stick when it comes to compensation for their work. And that sometimes gives the people who are the curators a sense of protecting them of not allowing their work to be used as widely as the law says it should be. So that's one way with a code of fairness, basically. We can have a conversation and say, well, understand the way you think about this, but let's take a look at another area where we're sharing resources and maybe you need to be more liberal or more permissive. So that's the kind of conversations I mean. 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.
