The Lincoln Reader weaves a biography of Abraham Lincoln written by sixty-five authors, meshing history, anecdotes and research to provide a fascinating view of the Emancipating President. Paul Angle, the noted Lincoln scholar, has selected passages from the works of Lincoln’s contemporaries, later biographers, and even Lincoln himself, to form a composite portrait of one of the wisest and most beloved American presidents. These passages, interwoven by Angle’s running commentary, blend into a single vivid narrative of Lincoln’s life, from his boyhood in Indiana to his assassination and funeral. First published in 1947, The Lincoln Reader has long been considered the most definitive, complete, and authentic retelling of the life of Abraham Lincoln.
