The research for this book was conducted in the Harry S. Truman Library, Independence, Missouri. Without a Glen Grant from Washington and Lee University, I would have been unable to manage the research, which is the backbone of this book. I thank Dean John Elrod, who arranged subvention for the preparation of the speech texts in "Part II: Collected Speeches," and Karen Lyle, who expertly typed the texts. Washington and Lee University also accorded me an academic leave to write the book.
The staff at the Truman Library was very helpful. I thank especially Phil Lagerquist and Pauline Testerman, who extended a helping hand with archival sources and audiovisual materials.
