Whitney's work reveals the legal and political spheres where Lincoln moved while providing eyewitness accounts and intimate stories shared by Lincoln himself. Whitney's unique vantage point informs analyses of everything from Lincoln's melancholic temperament to his colorful early career to views on his marriage and family life. Burlingame places Whitney's singular contributions within Lincoln studies but also weighs criticisms of the book and disputes over what information the author may or may not have invented.

A restored edition of an invaluable memoir, Lincoln the Citizen presents a wealth of overlooked biographical detail by one of the people who knew Lincoln best.
