The Letters of Theodore Roosevelt constitute a major contribution to the field of American history and literature. At the same time, they present an autobiography of matchless candor and vitality. They are at once a mine of information for the historian, a case study in astute and vigorous political leadership, and a delight to the general reader. All the letters needed to reveal Roosevelt's thought and action in his public and private life are included, with appropriate editorial comment; and each is printed in its entirety.

In the letters of 1901-1905, Roosevelt consolidates his position as President and party leader, settles the coal strike, deals with the politics of the Panama Canal, expands the Navy, extends the sphere of American interests abroad, achieves the Presidency in his own right, and works with the Russians and the Japanese to make the Peace in Portsmouth.
