The (original) Hardy Boys Mystery Stories (1927–1979)
The first 58 stories and the 38 revisions, along with the Detective Handbook and its revision, are considered by many collectors to form the Hardy Boys canon.
The Hardy Boys Mystery Stories ("Digests") (1979–2005)
This now-discontinued series of paperbacks started in 1979 as a continuation of the hardcover books, hence the volume numbers start as #59 and ended in 2005 with volume 190.
Volumes 59 through 85 were also released in hardcover with a dustjacket.
In 2005, Grossett & Dunlap released hardcover versions of volumes 59 through 66. These volumes were in the blue glossy flashlight cover format, similar to the original 58 covers. The artwork on these books was from the original Wanderer paperback covers, although severely cropped to fit the covers. To date, there is no news about plans for further Grossett & Dunlap hardcover versions.
