Nancy Drew (Revised) 

A series of middle grade novels written to appeal to young girls starring Nancy Drew who solves mysteries.  They were written by several people using the pen name Carolyn Keene.  The first thirty-four books in the series were later revised to be more up-to-date and to remove some unfavorable stereotypes beginning in  1959 until 1977.

This series includes the original 64 books starting with The Secret of the Old Clock and ending with Captive Witness (1981) and only includes the revisions of the first 34 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 not decided whether not to document the titles for the original series as of now.

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