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.

Collector's editions and foreign publications

From 1998 to 1999, Simon & Schuster published three Hardy Boys Casefiles Collector's Editions that contained three previously published Casefiles stories (Vol. 1 #'s 38, 39 and 40; Vol. 2 #'s 48, 51 and 52; Vol. 3 #'s 55, 58 and 59). In 2005, Simon & Schuster reprinted Vol. 3 in hardcover with a different cover that used the current Hardy Boys Mystery Stories (Digest) cover of a file folder with modified art from Hardy Boys #152, exclusively for Borders Bookstores.

The Canadian rights to the Casefiles and its spin-offs have been held by Paperjacks (April 1987-December 1989) and Distican, Inc./Simon & Schuster Canada (January 1990-present; Simon & Schuster US bought out Distican in 2002 and just changed the company name). Aside from inserting an ad for their 'Books By Mail' program, their address on the copyright page, and a small Maple Leaf with "Printed In Canada" being put on the front covers, and distributing the books, Paperjacks was allowed no other editorial/layout changes to the books. Once Distican took over the rights in January 1990, the books were all published in the US and just distributed by Distican in Canada with no publishing occurring in Canada.

Simon & Schuster UK have published many 2-in-1 and 3-in-1 books of the Casefiles since the early 1990s in the UK and other British Commonwealth Nations (except Canada). In 2005/06 Simon & Schuster UK reissued four Casefiles under the Undercover Brothers label, with two other books being planned but cancelled before publication.

Armada/Collins held the UK/British Commonwealth (except Canada) rights to the Casefiles from about 1988 till 1991, with reprint rights continuing on throughout the 1990s, allowing Armada to publish different 2-in-1 and 3-in-1 books of the first 10 Casefiles.

The Hardy Boys are: The Clues Brothers (1997–2000)

The Clues Brothers books were aimed at younger readers, particularly in third and fourth grades. The series was introduced in 1997 and was cancelled in 2000 for lack of popularity.

This series had some big differences from the other Hardy Boys books, such as:
  • The Hardy Boys don't solve major crimes as they do in the others.
  • In these books, Frank and Joe are only 9 and 8, unlike the other books where they are 18 and 17.
  • They go to Bayport Elementary School
