Bringing together philosophers of law and philosophers of technology, this book addresses the issues that arise in the tension between freedom of and property in information. Addresses business models, government strategies and legal frameworks concerning the collection, organisation and control of data, the book asks whether it is in the very nature of information to be free. Analysing the various political and ethical implications raised by this question - including, for example, open access, the hacker ethos, the market in information, and so on - this book will be of considerable interest to those working on the contemporary dimensions of freedom of information, data protection, and intellectual property rights.
