This edition contains not only the titular "84 Charing Cross Road" but also "The Duchess of Bloomsbury Street", a diary of Helene Hanff's visit to London a few years after the events of the previous book. Both are wonderful, although the original series of letters maybe has the edge over the other, diary-format, book. Helene Hanff's enthusiasm for books, her kindness and her humour shine through both.  A real delight.
