In the twelve years I have been working on this book, I have accumulated debts so many and so great that it is impossible to acknowledge them all here. Nevertheless, in a book about the relationship between individual authorship and collaborative work, I would be remiss if I did not try. First, I thank Dan Ernst for believing this was a book, for reading the manuscript several times and offering penetrating editorial suggestions, and for seeing it through to publication. I am grateful for financial and material support from the deans, librarians, and staff of the law schools of Loyola Marymount University, the University of Southern California, Duke University, and the University of California, Irvine, and from the Hagley Museum and Library. An embarrassingly large number of law students at Loyola, USC, UCLA, and Duke did research: Amin Aminfar, Geoffrey Moore, and Katherine Scott made extraordinary research and editorial contributions; Kim Kisabeth got the manuscript in shape at the end; and Richard Allen, Kristin Beattie, Michael Blacher, Eric Compere, Robin Diem, Laura Durity, Kelly Firment, Ian Fried, Jennifer La Macchia, An Le, Michael LeBoff, Lin Lee, Max Rieger, Mary Roccapriore, and Kathrin Weston all helped with the research.
Some parts of the book were published in article form, as “Removing the ‘Fuel of Interest’ from the ‘Fire of Genius’: Law and the Employee-Inventor, 1830–1930,” 65 University of Chicago Law Review 1127 (1998); “Working Knowledge: Trade Secrets, Restrictive Covenants in Employment, and the Rise of Corporate Intellectual Property, 1800–1920,” 52 Hastings Law Journal 441 (2001); “Authors at Work: The Origins of the Work-for-Hire Doctrine,” 15 Yale Journal of Law and the Humanities 1 (2003); and “Credit Where It’s Due: The Law and Norms of Attribution,” 95 Georgetown Law Journal 49 (2006). I am grateful to the staff and editors of these law reviews for their assistance at the time the articles were published and for permission to include portions of them here.
