THE BROWN UNIVERSITY LIBRARY STAFF HAS PROVIDED INDIS pensable help in the preparation of this book. John Ettlinger is most thankful to Martha Mitchell of the library's Department of Archives. Jennifer Lee of the John Hay Library at Brown kindly called Michael Burlin- game's attention to the manuscript prepared by Ettlinger. She and her colleagues, including Samuel Streit and Jean Rainwater, have been unfailingly helpful throughout the completion of this project. To them is owed a great deal.
John Y. Simon, the dean of documentary editors in the field of American history, has been an inspiration, a goad, and a friend to Burlingame, encouraging him throughout the years he worked on this book and other Lincoln studies. Burlingame counts himself supremely lucky to have Simon's counsel and friendship.
Wayne C. Temple, the chief deputy director of the Illinois State Archives in Springfield, and Thomas F. Schwartz, the Illinois state historian, have examined the manuscript and generously shared their extensive knowledge of Lincoln and his times. Lois Erickson McDonald (Brown '59), who has a special affinity for John Hay and the John Hay Library, has helped more than she knows to make this book possible.
Other librarians across the country have also provided invaluable assistance, especially at the Library of Congress, the National Archives, the Huntington Library, the New York Public Library, the New-York Historical Society, Allegheny College, the Illinois State Historical Library in Springfield, and particularly at Connecticut College in New London, where Burlingame has taught since 1968. The college's R. Francis Johnson Faculty Development Fund has helped defray some of the expenses involved in the research and writing of this book.
Lloyd Burlingame of Manhattan and Sue Burlingame Coover of Chevy Chase, Maryland, have been emotional rocks of Gibraltar as well as generous hosts who make Burlingame's research visits to New York and Washington, D.C., not only enjoyable but affordable. Cynthia Love McCollom and Kathy Nolan were very helpful in checking the accuracy of the annotations.
