Simon & Schuster

In 1979, the Hardy Boys books began to be published by Wanderer Books Simon & Schuster in paperback format. Though formatted differently from the original 58-volume series which continued under Grosset & Dunlap's control, these new books were published under the Hardy Boys Mystery Stories banner. These books feature increasingly contemporary cover illustrations and some books have multiple versions of the cover art.

To collectors of Hardy Boys and Nancy Drew books, books in the original series published at Simon & Schuster are called "Digests". This is due to the books resembling Digest-size paperbacks, differing from Grosset & Dunlap's hardcover books (one of the reasons Adams switched to Simon & Schuster was that Grosset & Dunlap did not like this move, while Simon & Schuster agreed to it).

In 2005, the first eight volumes from Wanderer (#59-66) were republished by Grosset & Dunlap, alongside the first eight Nancy Drew volumes from Wanderer. These republications went out of print in 2013.

Wanderer editions

The main plot, formula, and continuity of the books remained similar to the original Grosset & Dunlap books still being published at the time. After Harriet Adams died in 1982, the Syndicate continued with five of its partners (Adams' remaining three children, plus authors Nancy Axelrod and Lilo Wuenn), until its sale to Simon & Schuster in 1987.

Night of the Werewolf was originally listed as the next book at the end of Sting of the Scorpion. Grosset & Dunlap continued to list this until they lost a court case against the Syndicate and Simon & Schuster in May 1980. The book was later revised to eliminate the next title and instead referenced the first book in the series, The Tower Treasure. They later published Night of the Werewolf and the next seven titles in 2005, with the permission and collaboration of Simon & Schuster. These last eight titles were discontinued once the license ran out.

Minstrel editions

After volume 85, the series took a two-and-a-half-year hiatus due to the sale of the Stratemeyer Syndicate to Simon & Schuster. At this point, book packager Mega-Books took over the series, and hired different ghostwriters for the job (many of whom are still unknown). Mega-Books worked on the series until #153 Eye On Crime in 1998. Starting with #154 The Caribbean Cruise Caper, Simon & Schuster handled all books internally. The ghostwriters who are known are ones who have either been discovered through other resources, or have publicly revealed themselves as a ghostwriter for the series.

The Hardy Boys Casefiles Series (1987–1998)

The Hardy Boys Casefiles are aimed at early-to-mid teen readers and have more mature themes, including espionage, murder, and slight romance. The new direction the series would take was set in the first volume, Dead On Target, as a bomb planted in the Hardy Boys' car blows up Joe's longtime girlfriend, Iola Morton, in the first chapter. Book packager Mega-Books and Simon & Schuster released the first two Casefiles under the Archway imprint in April 1987 and continued to release a new title monthly until November 1997. In January 1998 the last Casefile, #127 Dead in the Water, was released. This series was published in mass-market, or rack-sized, paperbacks to widen the distribution of the books to supermarkets and other outlets. In September 1987 the Hardy Boys Digest series was revived and continued with #86 The Mystery of the Silver Star. Events from the Casefiles are not referenced in the Digest series, and Iola Morton is alive and connected with Joe Hardy as in the previous 85 titles. The Casefiles universe also merges with the Nancy Drew Files and Tom Swift worlds in titles published as A Nancy Drew and Hardy Boys SuperMystery and A Hardy Boys and Tom Swift UltraThriller. Several spin-off series were cancelled by Simon & Schuster at the end of 1997, including The Hardy Boys Casefiles.

This series follows the formula of the main characters and their friends typically involved in separate mysteries that end up being connected. The sleuths join forces to solve the overall mystery. This series is based in the Nancy Drew Files and Hardy Boys Casefiles continuity, so murder, romance, and flirtation between the series regulars are common. Nancy Drew and Frank Hardy share an attraction in this series, though after a brief kiss in The Last Resort this attraction is not acted on. Subsequent books focus on the respect and friendship that developed between the two and their continued feelings for Ned Nickerson and Callie Shaw. Several spin-off series were cancelled by Simon & Schuster at the end of 1997, including the Nancy Drew and Hardy Boys SuperMystery series. Starting in 2007, in order to differentiate between the new Super Mystery series, many fans started referring to this series as SuperMystery'88.

Hardy Boys and Tom Swift Ultra Thriller Series (1992–1993)

The two-volume Ultra-Thriller series is a short-lived Hardy Boys spin-off that joined boy inventor Tom Swift with the crime-solving Hardy Boys, Frank and Joe. Although the Franklin W. Dixon pseudonym was used, the series was more akin to the then-current Tom Swift IV series and listed in the Tom Swift books as part of that series. Published as mass-market paperback books under the Archway imprint of Simon & Schuster. Both books were written by Bill McKay.

1. Time Bomb
2. The Alien Factor

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 throughout the 1990s, allowing Armada to publish different 2-in-1 and 3-in-1 books of the first 10 Casefiles.

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. Starting in 2013 the series is available as ebooks.

This series had some big differences from the other Hardy Boys books, such as:

• The Hardy Boys do not solve major crimes as they do in the others.
• In these books, Joe and Frank are only 8 and 9, unlike the other books where they are 17 and 18.
• They go to Bayport Elementary School; in the others, they go to Bayport High School.

Notes

1. Although it cannot be confirmed, Stratemeyer is the most accepted choice.
2. McFarlane's credit is disputed, due to a number of differences between writing style from his other books, and more frequent and obvious racism that the series was criticized for in later years.
3. McFarlane's credit is disputed, due to a number of differences between writing style from his other books, even though he claims authorship of The Secret Warning in his autobiography Ghost of the Hardy Boys. However, John Button's sole authorship of the entire manuscript is also in dispute, despite signed author records showing that he apparently wrote a manuscript for the book, due to a number of differences in writing style from his other books. There has been some speculation that the book, as it was released, was edited together by an editor at the Stratemeyer Syndicate from two different manuscripts that both McFarlane and Button wrote separately.
4. Retitled Deadly Chase in 1987.
5. Fuchs wrote his manuscript in German; Lilo Wuenn translated.
6. Harr was the grandson of Harriett Stratemeyer Adams, and great-grandson of Edward Stratemeyer.
7. Oiriginally titled and advertised as Mystery of the Space Shuttle.
8. Originally written for the Casefiles series.
9. Part of the "Operation Phoenix" Trilogy.
10. Part of the "Ring of Evil" Trilogy.
