Notes from Nancy Drew is a series of books intended for young readers. Here, 8-year-old Nancy and her friends are in third grade. The books are illustrated with rare black and white drawings. The "Notebooks" in the series title is a reference to the "blue notebook in which Nancy takes notes on mysteries and writes down what she learns." The stories end with a conclusion where readers are told what Nancy has learned. Series ended with book 69 in December 2005 and was revived as Nancy Drew and the Clue Crew.
