George Lyman Kittredge's insightful editions of Shakespeare have endured in part because of his eclecticism, his diversity of interests, and his wide-ranging accomplishments — all of which are reflected in the valuable notes in each volume. The plays in the New Kittredge Shakespeare series retain the original Kittredge notes and introductions, changed or augmented only when modernization is necessary. These new editions also include introductory essays by contemporary editors, notes on the plays as they have been performed on stage and film, and additional student materials.
