The authors would like to thank the following persons and institutions, without whom this work would never have been possible: Cal Morgan, who believed in us; Michelle Brower, our rockstar agent; Stephanie Hitchcock, our precise and long-suffering editor; Bauman Rare Books and Honey & Wax Booksellers, where Rebecca learned her trade; the specialists and advance readers who gave us notes: Nick Wilding, Russel Maret, Adam Hooks, Rachel D’Agostino, John Windle, Elizabeth Denlinger, Vic Zoschak, Robert Green, Ina Saltz, Loren Glass, Mitch Fraas, Jonathan Kearns, Ben Skerker (to whom credit is due for the Feng Shui joke), and Mike Smith; institutions that were kind to us, especially University of Virginia’s Rare Book School and University of Pennsylvania; our children, who are too young to have been anything other than obstructions, but screw it, thanks, Elliott and Anson; and lastly, a special danke to Johann Gensfleisch zur Laden zum Gutenberg: you weren't the first to invent movable type, and virtually no one credited you properly for two hundred fifty years, but you gave the world a European single-pull printing press and without you the subjects of this book (and the physical book itself) would not exist. Rest in peace, bro.
