The author wishes to extend a note of sincere appreciation to the entire staff of the Herbert Hoover Presidential Library in West Branch, Iowa, and to director Richard Norton Smith. A special recognition is also proffered to archivists Dwight M. Miller and Dale C. Mayer, whose suggestions concerning appropriate manuscripts were invaluable. A thank you is extended to the Herbert Hoover Presidential Library Association for grants awarded in support of research for this book. Without the association's financial commitment, this book would not have been possible. A word of thanks is offered to my wife, Shirley, who worked tirelessly to help gather articles and documents that bolstered my search for evidence.
A thank you also is extended to Robert Reid, associate professor of journalism at the University of Illinois at Urbana-Champaign, and Thomas B. Littlewood, professor of journalism at the University of Illinois, for their suggestions and help. A note of appreciation is offered to the University of Illinois vice chancellor's office, which funded a mini-grant for travel. Donald Lisio, professor of history at Coe College in Cedar Rapids, Iowa, also played an instrumental part in the compilation of information for the chapter on the Bonus March.
Finally, a note of gratitude is extended to my family, including especially my wife, but also by children, Cynthia, Andrew, and Rebecca, for their patience while this work was completed.
