If you go to the familiar Google search page and click the intimidating link marked "advanced search," you come to a page that gives you more fine-grained control over the framing of your query. Nestled among the choices that allow you to pick your desired language, or exclude raunchy content, is an option that says "usage rights." Click "free to use or share" and then search for "physics textbook" and you can download a 1,200-page physics textbook, copy it, or even print it out and hand it to your students. Search for "Down and Out in the Magic Kingdom" and you will find Cory Doctorow's fabulous science fiction novel, online, in full, for free. His other novels are there too—with the willing connivance of his commercial publisher. Search for "David Byrne, My Fair Lady" and you will be able to download Byrne's song and make copies for your friends. You'll find songs from Gilberto Gil and the Beastie Boys on the same page. No need to pay iTunes or worry about breaking the law. 2

Go to the "advanced" page on Flickr, the popular photo sharing site, and you will find a similar choice marked "Creative Commons License." Check that box and then search for "Duke Chapel" and you will get a selection of beautiful photos of the lovely piece of faux Gothic architecture that sits about three hundred yards from the office where I am writing these words. You can copy those photos, and 66 million others on different subjects, share them with your friends, print them for your wall, and, in some cases, even use them commercially. The same basic tools can be found on a range of specialized search engines with names like OWL Music Search, BlipTV, SpinExpress, and OERCommons. Searching those sites, or just sticking with the advanced options on Google or Yahoo, will get you courses in music theory, moral philosophy, and C++ programming from famous universities; a full-length movie called Teach by Oscar-winning director Davis Guggenheim; and free architectural drawings that can be used to build low-cost housing. At the Wellcome Library, you will find two thousand years of medical images that can be shared freely. Searching for "skeleton" is particularly fun. You can even go to your favorite search engine, type in the title of this book, find a site that will allow you to download it, and send the PDF to a hundred friends, warmly anticipating their rapturous enjoyment. (Better ask them first.) 3

All this copying and sharing and printing sounds illegal, but it is not (at least if you went through the steps I described). And the things you can do with this content do not stop with simply reproducing it, printing it on paper, or sending it by e-mail. Much of it can be changed, customized, remixed—you could rewrite the module of the class and insert your own illustrations, animate the graphs showing calculus in action, morph the photo into something new. If you search for a musician with the unpromising name "Brad Sucks," you will find a Web site bearing the modest subtitle "A one man band with no fans." Brad, it turns out, does not suck and has many fans. What makes him particularly interesting is that he allows those fans, or anyone else for that matter, to remix his music and post their creations online. I am particularly fond of the Matterovermind remix of "Making Me Nervous," but it may not be to your taste. Go to a site called ccMixter and you will find that musicians, famous and obscure, are inviting you to sample and remix their music. Or search Google for Colin Mutchler and listen to a haunting song called "My Life Changed." Mr. Mutchler and a violinist called Cora Beth Bridges whom he had never met created that song together. He posted a song called "My Life" online, giving anyone the freedom to add to it, and she did—"My Life." Changed. 4

On December 15, 2002, in San Francisco, a charitable organization called Creative Commons was launched. (Full disclosure: I have been a proud board member of Creative Commons since its creation.) Creative Commons was the brainchild of Larry Lessig, Hal Abelson, and Eric Eldred. All the works I have just described—and this book itself—are under Creative Commons licenses. The authors and creators of those works have chosen to share it with the world, with you, under generous terms, while reserving certain rights for themselves. They may have allowed you to copy it, but not to alter it—to make derivative works. Or they may have allowed you to use it as you wish, so long as you do so noncommercially. Or they may have given you complete freedom, provided only that you attribute them as the owner of the work. There are a few simple choices and a limited menu of permutations. 5

What makes these licenses unusual is that they can be read by two groups that normal licenses exclude—human beings (rather than just lawyers) and computers. The textbooks, photos, films, and songs have a tasteful little emblem on them marked with a "cc" which, if you click on it, links to a "Commons Deed," a simple one-page explanation of the freedoms you have. There are even icons—a dollar with a slash through it, for example—that make things even clearer. Better still, the reason the search engines could find this material is that the licenses also "tell" search engines exactly what freedoms have been given. Simple "metadata" (a fancy word for tags that computers can read) mark the material with its particular level of freedoms. This is not digital rights management. The license will not try to control your computer, install itself on your hard drive, or break your TV. It is just an expression of the terms under which the author has chosen to release the work. That means that if you search Google or Flickr for "works I am free to share, even commercially," you know you can go into business selling those textbooks, or printing those photos on mugs and T-shirts, so long as you give the author attribution. If you search for "show me works I can build on," you know you are allowed to make what copyright lawyers call "derivative works." 6

The idea behind Creative Commons was simple. As I pointed out in the first chapter, copyright adheres automatically on "fixation." As soon as you lift the pen from the paper, click the shutter, or save the file, the work is copyrighted. No formalities. No need even to use the little symbol (C). Once copyrighted, the work is protected by the full might of the legal system. And the legal system's default setting is that "all rights are reserved" to the author, which means effectively that anyone but the author is forbidden to copy, adapt, or publicly perform the work. This might have been a fine rule for a world in which there were high barriers to publication. The material that was not published was theoretically under an "all rights reserved" regime, but who cared? It was practically inaccessible anyway. After the development of the World Wide Web, all that had changed. Suddenly people and institutions, millions upon millions of them, were putting content online—blogs, photo sites, videologs, podcasts, course materials. It was all just up there. 7

But what could you do with it? You could read it, or look at it, or play it presumably—otherwise why had the author put it up? But could you copy it? Put it on your own site? Include it in a manual used by the whole school district? E-mail it to someone? Translate it into your own language? Quote beyond the boundaries of fair use? Adapt for your own purposes? Take the song and use it for your video? Of course, if you really wanted the work a lot, you could try to contact the author—not always easy. And one by one, we could all contact each other and ask for particular types of permissions for use. If the use was large enough or widespread enough, perhaps we would even think that an individual contract was necessary. Lawyers could be hired and terms hashed out. 8

All this would be fine if the author wished to retain all the rights that copyright gives and grant them only individually, for pay, with lawyers in the room. But what about the authors, the millions upon millions of writers, and photographers and musicians, and filmmakers and bloggers and scholars, who very much want to share their work? The Cora Beth Bridges of the world are never going to write individual letters to the Colin Mutchlers of the world asking for permission to make a derivative work out of "My Life." The person who translated my articles into Spanish or Mandarin, or the people who repost them on their Web sites, or include them in their anthologies might have asked permission if I had not granted it in advance. I doubt though that I would have been contacted by the very talented person who took images from a comic book about fair use that I co-wrote and mashed them up with words from a book by Larry Lessig, and some really nice music from someone none of us had ever met. Without some easy way to give permission in advance, and to do so in a way that human beings and computers, as well as lawyers, can understand, those collaborations will never happen, though all the parties would be delighted if they did. These are losses from "failed sharing"—every bit as real as losses from unauthorized copying, but much less in the public eye. 9

Creative Commons was conceived as a private "hack" to produce a more fine-tuned copyright structure, to replace "all rights reserved" with "some rights reserved" for those who wished to do so. It tried to do for culture what the General Public License had done for software. It made use of the same technologies that had created the issue: the technologies that made fixation of expressive content and its distribution to the world something that people, as well as large concentrations of capital, could do. As a result, it was able to attract a surprising range of support—Jack Valenti of the Motion Picture Association of America and Hillary Rosen of the Recording Industry Association of America, as well as John Perry Barlow of the Grateful Dead, whose attitude toward intellectual property was distinctly less favorable. Why could they all agree? These licenses were not a choice forced on anyone. The author was choosing what to share and under what terms. But that sharing created something different, something new. It was more than a series of isolated actions. The result was the creation of a global "commons" of material that was open to all, provided they adhered to the terms of the licenses. Suddenly it was possible to think of creating a work entirely out of Creative Commons-licensed content—text, photos, movies, music. Your coursebook on music theory, or your documentary on the New York skyline, could combine your own original material with high-quality text, illustrations, photos, video, and music created by strangers. One could imagine entire fields—of open educational content or of open music—in which creators could work without keeping one eye nervously on legal threats or permissions. 10

From one perspective, Creative Commons looks like a simple device for enabling exercise of authorial control, remarkable only for the extremely large number of authors making that choice and the simplicity with which they can do so. From another, it can be seen as re-creating, by private choice and automated licenses, the world of creativity before law had permeated to the finest, most atomic level of science and culture—the world of folk music or 1950s jazz, of jokes and slang and recipes, of Ray Charles's "rewording" of gospel songs, or of Isaac Newton describing himself as "standing on the shoulders of giants" (and not having to pay them royalties). Remember, that is not a world without intellectual property. The cookbook might be copyrighted even if the recipe was not. Folk music makes it to the popular scene and is sold as a copyrighted product. The jazz musician "freezes" a particular version of the improvisation on a communally shared set of musical motifs, records it, and sometimes even claims ownership of it. Newton himself was famously touchy about precedence and attribution, even if not about legal ownership of his ideas. But it is a world in which creativity and innovation proceed on the basis of an extremely large "commons" of material into which it was never imagined that property rights could permeate. 11
