ACKNOWLEDGMENTS

SO MANY PEOPLE CONTRIBUTED in so many ways to this book that I am doomed to fail in acknowledging them all. It is difficult to thank a loose-edged network.

Two institutions have been especially helpful. Harvard’s Berkman Center for Internet & Society where I am a senior researcher, and the Harvard Library Innovation Lab, where I am co-director, alongside Kim Dulin, together provide the intellectual milieu that forms and challenges ideas, the companionship and collegiality that turns tasks into pleasure, and the resources to pursue ideas.

I am especially grateful to the members of the Berkman Book Club (which is for writing books, not reading them) for their critiques as this book developed, and for the emotional support all writers need even when we pretend we’re pretending otherwise.

A long list of people have helped me with ideas, by reading sections, by engaging in discussions with me, and in general by being generous with their time and expertise. This list is terribly incomplete, but it is at least alphabetical: AKM Adam, Jacob Albert, Patti Anklam, Solon Barocas, Isabel Walcott Draves, Mark Federman, Dan Gillmor, Timo Hannay, Terry Heaton, Harry Lewis, Maura Marx, Bob Morris, Beth Noveck, Andy Orem, Howard Rheingold, Peter Suber, Barbara Tillett, Catherine White, and John Wilbanks.

I owe a special debt to a few other people. I am lucky beyond words to have access to Ethan Zuckerman’s outsized brain and heart, and to his friendship. John Palfrey has supported me as a colleague and friend and, despite my having a few decades on him, has been an important mentor. The team of developers and designers at the Library Innovation Lab every day expands the horizons of what I thought possible. Eszter Hargittai’s rigorous research standards and good humor have affected me, albeit never enough. Christian Sandvig has been generous with his ideas and sources over the course of always stimulating discussions. Clay Shirky as a friend and thinker has more influence on me than he thinks or wants. Tim Sullivan gave me permission to let the topic assume the form that it wanted. Tim Bartlett, my editor, gave this book the systematic and insightful critique authors dream of. Christine Arden gave it a superb copy-editing pass that improved it on multiple levels. David Miller, my agent and friend, was essential to getting me from an idea to a book; it has been my tremendous good fortune to have worked with him and Lisa Adams on four books over the past ten years. My wife, Ann Geller, is my first reader and love. Our three children—Nechama, Leah, and Nathan—have lost none of their capacity to delight as they have grown into two women and one man.
