Free online book, by James Boyle, introduces readers to the idea of the public domain and describes how it is being tragically eroded by our current copyright, patent, and trademark laws. In a series of fascinating case studies, Boyle explains why gene sequences, basic business ideas and pairs of musical notes are now owned, why jazz might be illegal if it were invented today, why most of 20th century culture is legally unavailable to us, and why today?s policies would probably have smothered the World Wide Web at its inception. Appropriately given its theme, the book will be sold commercially but also made available online for free under a Creative Commons license......(free).....
