Nancy Drew Mystery Stories 1-56
Still in print today are the classic Nancy Drew Mystery Stories--volumes 1-56. You might
be surprised in purchasing the yellow spine picture covers at your local bookstores to find that
the first 34 stories are a rather baffling mystery! They may be shorter than you remember them, the language
has been updated, and Nancy's snappy roadster is now your run of the mill convertible. In short,
they have been revised.
Beginning in 1959 until 1978, the first 34 stories were revised by the
Stratemeyer Syndicate. These revisions removed stereotypes, outdated language, and overall updated
the stories and shortened them for modern readers.
Never fear, if you are missing an original text or want to read one and you cannot find one
in grandma's attic, you can sleuth them out at used bookstores, antique malls, or online at
Books reprinted 1-21 of the originals--just as you remember them.
The key to deciphering whether you have an original or not, is that your
book will have 25 chapters( not 20. )
These books are considered the "classic" series due to their being the original mysteries and
in print for over 75 years and counting while paperback series and spin-offs have come and gone.
These are the
stories that have been passed down from generation to generation and have become
favorites of Nancy
Over the years, the cover illustrations and internal illustrations underwent changes as well.

various styles of dust jackets, cover board styles, endpapers, and yellow spine picture cover types.

original and one for the revision where the revision varies significantly in plot or story from
