In 1999, law professor Larry Lessig wrote a fascinating book titled Code and Other Laws of Cyberspace. But law and technology have the ugly habit of changing, so the book now needs some revisions. Rather than do it entirely himself, however, the monumentally creative Lessig has established a wiki that will allow anybody to edit, improve, and revise the text. The goal, he writes, is “to open the editing process to all, to draw upon the creativity and knowledge of the community. This is an online, collaborative book update; a first of its kind.” Code v.2, as the revised book will be called, comes out later this year. Here’s the FAQ if you want to learn more. And here’s a Business Week interview in which the estimable professor explains the method behind his editorial madness.
