I would like to thank Donald Yacovone for bringing to bear his considerable expertise on the Civil War and Abraham Lincoln in the preparation of the headnotes that preface the selections of Lincoln's writings. In addition, I would like to thank John Sellers, Sheldon Cheek, Tom Wolejko, Julie Wolf, Aditya Basheer, and Joyce Clifford for their research assistance. Allen Guelzo, John Stauffer, Ira Berlin, Philip Kunhardt, Peter Kunhardt, Ted Widmer, Donald Yacovone, David Herbert Donald, James McPherson, and Tina Bennett read several drafts of my introduction, and provided quite helpful criticisms and suggestions.
This book grew out of my research for my PBS documentary, Looking for Lincoln, which marks the bicentennial of Abraham Lincoln's birth. I would like to thank Doris Kearns Goodwin, and my fellow executive producers, William Grant, Peter Kunhardt, and Dyllan McGee, and my producers, Barak Goodman, John Maggio, and Muriel Soenens, for helping me to understand my own relationship to Lincoln and Lincoln's relationship to our times.
I would also like to thank my agent, Tina Bennett, and my editor at Princeton University Press, Hanne Winarsky, for their support of the publication of this book to coincide with the air ing of our documentary series. Lauren Lepow expertly edited my introduction, helping me to understand what it was I was trying to say.
The texts of Lincoln's writings and speeches are taken from The Collected Works of Abraham Lincoln [CW], edited by Roy P. Basler, published under the auspices of the Abraham Lincoln Association (New Brunswick: Rutgers University Press, 1953– 1990), available online at http://quod.lib.umich.edu/l/lincoln.
