"Anyone interested in the future of culture in the Internet age will want to read this carefully reasoned, pragmatic yet passionate book. Dr Aigrain enlightens our understanding of the present while opening our minds to new, better ways of reaping the cultural and social benefits of the digital revolution." -- Prof. Juan Carlos De Martin - Faculty Director, NEXA Center for Internet & Society, Politecnico di Torino|"More than an impassioned defense of the Creative Contribution, this essay is a must read for anyone interested in a viable economic structure adapted to the realities of the digital environment. Precise, well argued and lucid, it offers a clear and pragmatic alternative to the failed models grounded in a simple extension of Copyright and Intellectual property conventions. Aigrain's work is essential for developing and implementing a just and appropriate economic model for the circulation of cultural production on the net." -- Milad Doueihi, Chaire de recherche sur les cultures numériques, Université Laval (Québec)|"Philip Aigrain has written am ambitious and important book that seeks to open minds and shape debates over the legal regimes that govern the sharing of information in an Internet age. Aigrain is unusually well informed about the nuances of fresh thinking about the legal, social and economic aspects of sharing, and he presents incredibly useful and shrewd insights into the twin challenges of facilitating lawful sharing of information and providing sustainable rewards for creative communities involved in the production of cultural works." -- James Love, Director, Knowledge Ecology International|"Philippe Aigrain writes a brave book, venturing out into difficult territory. He articulates the value of sharing and collaboration in the Internet age; he explains why - contrary to what is generally stated - non-commercial sharing of cultural works by individuals is a widely beneficial practice. Most importantly, he explores what can be done in practice to sustain creativity in the new digital landscape." -- Charles Nesson is the Weld Professor of Law and Founder of the Berkman Center for Internet & Society at Harvard University
