Also until I read the book I did not realize that Charing Cross Road was a real place. The whole book is based on a collection of correspondence between Helene Hanff, an avid book reader, and Frank Doel an agent for British bookseller.
My wife has taken this one step further and is collecting all the books that were mentioned in the correspondence. Some of these books appear to have been reprinted due to this publication.
If you can find it there is a book called “The Library of Helen Hanff.”
I wonder what became of all the other people described in the correspondents after the book.
