The Future of Ideas: the fate of the commons in a connected world (2001) is a book by Lawrence Lessig, a professor of law at Stanford Law School, who is well known as a critic of the extension of the copyright term in US. It is a continuation of his previous book Code and Other laws of Cyberspace, which is about how computer programs can restrict freedom of ideas in cyberspace. In the end, he stresses the importance of existing works entering the public domain in a reasonably short period of time, as the founding fathers intended.
