“Two Bits is only partly about geeks, code, technology, or software. It’s also about the cultural significance of those elements and how they’ve influenced, and will continue to impact, the ways people work, organize, collaborate, and even think. . . . Kelty’s fine book provides an anthropological basis to investigate our own practices and community.” — Kevin M. Ford, College and Research Libraries

“[A] dense and rich book. . . . I can heartily recommend it to anyone who finds some of the ideas on this blog vaguely amusing: it's the work of a kindred spirit.” — Glyn Moody, Open . . . blog

“[A] superb ethnography. . . . [S]imultaneously the best anthropology monograph and the most important book on information technology of the year, if not the decade.” — C. S. Peebles, Choice

“[A] very good discussion and well worth pursuing.” — Ehud Lamm, Lambda the Ultimate blog

“[W]ill fascinate and surprise even those geeks with a relatively deep historical sense of this world. . . .” — Gabriella Coleman, Interprete blog

“Christopher Kelty's Two Bits is excellent -- it brings detailed ethnographic material combined with complex conceptual innovations all in relation to a phenomenon of major and increasing significance in the world that has so far been little studied in academia. . . . Two Bits is a key intervention into and contribution to analysis of the socially and culturally important field of Free Software and more generally to Internet Studies and social theory.” — Tim Jordan, Resource Center for Cyberculture Studies

“The significance of this book is wider than its subtitle might at first suggest. Its ethnographic focus, so-called ‘free software’, will likely be exotic to many readers. But what the book offers is a remarkable perspective on the wider computing infrastructure that has found its way nearly everywhere over the past decades. . . . This is a rare, richly detailed social science account of an important technology’s history. . . . Overall the book will likely appeal to a broad audience, and it will be difficult to ignore in fields of study focused on media, science, and technology, and globalization and change, in any way involving the Internet.” — Jens Kjaerulff, Journal of the Royal Anthropological Institute

“[A] closely argued, well-defended, painstakingly referenced treatise covering one of the most complex, and possibly least understood, cultural movements of recent decades. . . . [D]eeply engaging.” — John Gilbey, Times Higher Education

“[R]ich with empirical insight and exceptionally well written, Two Bits is delightful to read. I recommend the book to readers interested in open source, technology, and social change. . . .” — Zack Kertcher, American Journal of Sociology

“Considering the scope of the subject matter, the book is not especially steeped in technical jargon, and is therefore highly readable for a wide and varied audience. Contrary to first impression this book is not specifically directed towards geeks, software code authors, or other computer nerds, although these individuals will find the book informative and inspiring. It also should be read by all those who have positions of influence such as teachers, cultural studies academics, government decision/policy makers and of course members of the legal profession.” — Rob Harle, Leonardo

“I think Kelty’s book deserves a wide readership — especially among nerds trying to make sense of the past decade, let alone to prepare for the next one.” — Scott McLemee, Inside Higher Ed

“In this study of the Free Software/Open Source movement, Christopher Kelty provides a fascinating look into a world that may initially seem arcane to those outside the field, but which illuminates many connections between ‘geek’ culture and the wider world as well. . . . In a moment marked by Wikipedia and Facebook, new connections and forms are emerging every day. Two Bits reaches beyond the technicalities of the Free Software movement to help provide productive ways to think about these non-traditional communities as they are only beginning to imagine themselves.” — Erica A. Farmer, Anthropological Quarterly

“It would be a great pity indeed if anthropologists, assuming they have no interest in software development, were to ignore the subtitle of this book. Because ‘the cultural significance of free software’ takes to heart matters of concern to all anthropologists. . . . They would miss a book that has as much to contribute to the anthropology of law as to the anthropology of religion, both much enhanced by the unusual perspective that emerges from software development. They would also miss a good read.” — Daniel Miller, American Anthropologist
