The Age of Innocence first appeared in four large installments in The
Pictorial Review, from July to October 1920. It was published that same
year in book form by D. Appleton and Company in New York and in London.
Wharton made extensive stylistic, punctuation, and spelling changes and
revisions between the serial and book publication, and more than thirty
subsequent changes were made after the second impression of the book
edition had been run off. This authoritative text is reprinted from the
Library of America edition of Novels by Edith Wharton, and is based on
the sixth impression of the first edition, which incorporates the last
set of extensive revisions that are obviously authorial.
