Wanderer Books (1979–1985)

The Triple Hoax was originally listed as the next book at the end of The Thirteenth Pearl. 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 Triple Hoax. However, they later published this book — and the seven after that — in 2005, with the permission and collaboration of Simon & Schuster, in celebration of Nancy Drew's 75th anniversary.

The main plot, formula, and continuity of the books remained similar to the original Grosset & Dunlap books still being published at the time. Harriet Adams was still involved in the Syndicate, even after she stopped writing the books in 1980. Simon & Schuster rejected her original manuscript for The Secret in the Old Lace, with the story being rewritten by Nancy Axelrad. After she died in 1982, the Syndicate continued with five of its partners (Adams' remaining three children, plus authors Axelrad and Lilo Wuenn), until its sale to Simon & Schuster in 1987.

During this period, the Syndicate began to hire new, younger writers, including Sharon Wagner, Richard Ballad, and James Duncan Lawrence. Ballad's two books, Captive Witness and The Sinister Omen, as well as The Emerald-Eyed Cat Mystery, were originally written for The Hardy Boys, but were rewritten for unknown reasons.

The final two books (#77 and #78) were "backdoor pilots" for the spin-off The Nancy Drew Files, which began in 1986. Due to this, and the sale of the Stratemeyer Syndicate, the series went on a two-year hiatus to retool the series.

Minstrel Books (1987–2001)

After volume 78, the series took a 2+1⁄2-year hiatus due to the sale of the Stratemeyer Syndicate to Simon & Schuster, and to begin The Nancy Drew Files spin-off. At this point, book packager Mega-Books took over the series, and hired different ghostwriters for the job (many of whom are still unknown). 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 series also gained Anne Greenberg as the new editor; Greenberg would oversee the series for the next 16 years, and become one of the most influential Nancy Drew editors that helped the books continue until the 21st century.

Due to the cancellation of The Nancy Drew Files in 1997, Simon & Schuster rewrote several unpublished manuscripts into books for the original series. These include The Wild Cat Crime (#141), The E-mail Mystery (#144), and The Case of the Captured Queen (#148).

The writing style of these books took a different direction than the books of the Syndicate; modern technology is mentioned (making the books seem somewhat dated very quickly), continuity errors are common, and the books become shorter (reducing the books from a 20-chapter/180-page format to a 16-chapter/150-page format). Characters Burt Eddleton and Dave Evans are eliminated entirely ( because of this, some fans were disappointed) and Nancy mostly has a habit of rotating between George, Bess, and Ned. This setup creates a more realistic layout, rather than having all six drop everything to join Nancy. In the late 1990s, continuity errors and text errors became more common.

Aladdin Books (2001–2003)

With the new millennium, the series changed publishers to the Aladdin subdivision of Simon & Schuster. With declining sales, and the departure of longtime editor Anne Greenberg, Simon & Schuster ended the original series in November 2003.

Continuity errors are common throughout these books: in No Strings Attached and Danger on the Great Lakes (both written by George Edward Stanley), Nancy and her friends are 17 rather than 18; Ned works at a company; and George has chestnut hair (rather than brown). In Werewolf in a Winter Wonderland, Ned is blond, and it is suggested that Nancy might be in college. Numerous typographic errors and mistakes are also found throughout these books.

United Kingdom

The Nancy Drew Mystery Series was published in a series of hardbacks and paperbacks in the United Kingdom, starting in 1971 and 1973. The British publisher was Collins, and its paperback imprint Armada Books (which also published the Hardy Boys and Three Investigators, among other series). When the Nancy Drew series was published in England, the order was changed significantly and the titles' numbering was revised from the American standard, as Armada was "obliged to publish No. 51 onwards before publishing Nos. 41-50".^[4][5]

Thus, the original fifty-six American Grosset & Dunlap-published titles become the first fifty UK titles, with #57-78 being published as #51-72. Collins, therefore, had a deal in place with both American publishers and, indeed, were obliged "for contractual reasons" to publish some of the later Simon & Schuster titles before some of the Grosset & Dunlap ones. Collins/Armada published the twenty-two Simon & Schuster/Wanderer titles in sequence, albeit off by six, and then finished publishing the six "missing" Grosset & Dunlap titles (including the first, The Secret of the Old Clock).

The twenty-two (US) Wanderer imprint titles were produced between 1979 and 1985, after which the main Nancy Drew Mystery Stories went on a short hiatus. During this time, Simon & Schuster began publishing The Nancy Drew Files series for older teenagers, and subsequently re-aligned the main series, moving it to a new imprint in 1987, with The Double Horror of Fenley Place, the first Nancy Drew title published under the American Minstrel imprint. Accordingly, after publishing twenty-two Wanderer (and seventy-eight overall) titles in the main Nancy Drew series, the Collins/Armada licence terminated in June 1992. The following month, Simon & Schuster itself began publishing the more recent Minstrel imprint titles under their Pocket Books UK imprint, starting with the now numerically-aligned #79.

Reader's Club

Nancy Drew was issued as a book club feature, the Nancy Drew Reader's Club, from 1959 to early 1961. In all, twelve volumes were issued, six in 1959 and six in 1960.^[6] These volumes were issued with new illustrations by artist Polly Bolian. The volumes matched Grosset & Dunlap's other Doubleday Book Club publication, Young Library. A full color jacket illustration was repeated as the frontispiece, and double-page pen and ink drawings highlighted the texts. References or notices for other volumes, and volume numbering, was removed from the text and the jackets.

Plans for additional titles were abandoned after two years and the series ceased publication in early 1961. The volumes are highly desired by today's collectors due to their original artwork and the scarcity of their dust jackets, made on inferior, lightweight matte paper instead of heavier-gauge glossy paper used on other editions. The books with jackets are considered scarce, those with a 1960 date being much more difficult to find by collectors.^[6]

Book club editions

Nancy Drew was issued in the yellow-spine picture format, as a book club, in 1962.^[7] The back covers were solid yellow, and spines feature no volume numbers. "Book Club Edition" appears on the title page. Only Volumes 1–32 were issued. In the 1970s, a book club offer was available directly from the publisher, but these volumes were exactly the same as regularly purchased volumes; they were simply mailed on schedule to the subscriber.

Twin Thriller

Several Nancy Drew books were published as two-volumes-in-one in the 1970s.^[8] Covers featured geometric clover designs on lilac grey, with a vignette from one of the two volumes' original cover art. All of the volumes are sequential, i.e., 1–2, 3–4, except for the final two issued. Volumes 17 and 24 appear together as one, as they were not revised until the mid-1970s.

Applewood Books reprints

Applewood Books began reprinting facsimile editions of the early Nancy Drew and Hardy Boys in 1991. The books feature the original dust jacket art, original illustrations (although not scattered through the text), original texts, and duplication binding of the early Nancy Drew format. Many of the volumes contain forewords from adult author fans of the series, such as Sara Paretsky. Applewood issued original series titles up to #21, The Secret in the Old Attic. Although Volumes 22 and 23, The Clue in the Crumbling Wall and The Mystery of the Tolling Bell, respectively, were featured in the 2006–2007 catalogue, these additional titles were not ultimately published as company representatives stated that sales of later volumes had tapered and plans to extend the line were discontinued in 2007.

Literarture lithographs

In late 2006, Literarture, licensed by Simon & Schuster, began releasing prints of classic Nancy Drew dust jacket artwork by Russell Tandy, Bill Gillies and Rudy Nappi derived from pristine vintage art elements and, in some cases, following extensive research, the original paintings themselves.^[9] The jackets were issued as limited-edition offset lithographs.

Grosset & Dunlap reissues

In early 2007, Grosset and Dunlap began retailing special volumes of Nancy Drew mysteries with original artwork but revised content in different product assortments and packaging.
