Book List

Series is Hardy Boys (Revised)

Hardy Boys (Revised):

A series of middle grade novels written to appeal to young boys starring two brothers, the sons of a famous detective, solving their own mysteries. They were written by several people using the pen name Franklin W Dixon.

This series includes the original 58 books starting with The Tower Treasure and ending with The Sting of the Scorpion (1978) and only includes the revisions of the first 38 books. The copyright dates for these are the revised dates since I consider the originals to be different "books" even though they have the same title. I have decided to duplicate the titles for this series and the original series since the works in this series.

For the books in this series I've added the "true" author to the list (even if this is questionable) along with the psuedonym Franklin W Dixon that is credited on each book.
