This new expanded and updated edition contains more than 500 notes keyed to the 2006 Harper Perennial Modern Classics, the 1986 Harper Perennial Library, and the 1967 Bantam editions. The majority of notes are interpretive, although some are designed to provide a historical context or to recover the meaning of a reference that, over time, has proved to be ephemeral. This new edition adds quotations and paraphrases drawn from criticism published since 1994. The result is more than seventy new entries in the list of works cited. More than fifty annotations have been added and approximately eighty annotations have been expanded.
