Each is presented in the original language, with normalized spelling and substantial annotations for modern readers. Among the new added to the Second Edition are the much-requested "Merchant s Tale" and the "Tale of Sir Thopas." "Sources and Backgrounds" are included for the General Prologue and for most of the tales, enabling students to understand The Canterbury Tales in light of relevant medieval ideas and attitudes and inviting comparison between Chaucer s work and his sources. "Criticism" includes nine essays, four of them new to this edition, by leading Chaucerians, among them F. R. H. DuBoulay, E. Talbot Donaldson, Barbara Nolani, and Lee Patterson. A Chronology and Selected Bibliography are also included.
