Ace Books

Ace Books is the oldest active specialty publisher of science fiction and fantasy books. The company was founded in New York City in 1952 by Aaron A. Wyn, and began as a genre publisher of mysteries and westerns. It soon branched out into other genres, publishing its first science fiction (sf) title in 1953; this was a successful innovation, and within a few years, sf titles outnumbered both mysteries and westerns. Other genres also made an appearance, including nonfiction, gothic novels, media tie-in novelizations, and romances.

Ace became known for the "dos-à-dos" binding format used for many of its early books, although it did not originate the format. Most of the early titles were published in this "Ace Double" format, and Ace continued to issue books in varied genres, bound "dos-à-dos", until 1973. These have proved attractive to book collectors, and some rare titles in mint condition command prices up to $1,000.

Ace, along with Ballantine Books, was one of the leading S.F. publishers for its first ten years. With the death of owner A. A. Wyn in 1967, however, the company's fortunes began to decline. Two prominent editors, Donald A. Wollheim and Terry Carr, left in 1971, and in 1972 Ace was sold to Grosset & Dunlap. Despite financial troubles, there were further successes, particularly with the third Ace Science Fiction Specials series, for which Carr was the editor. Further mergers and acquisitions resulted in the company becoming a part of Berkley Books. Ace then became an imprint of Penguin Group (USA); its editorial team is also responsible for the Roc Books imprint, although the two imprints maintain a separate identity.cite web | url = http://www.sfcanada.ca/winter2005/johnmorganinterview.htm | title = SF Canada Article - "An Interview with Editor John Morgan" by Celu Amberstone| accessmonthday=10 May | accessyear = 2006]

Company founding and the Ace Doubles concept

Editor Donald A. Wollheim was working at Avon Books in 1952, but disliked his job. While looking for other work, he tried to persuade A. A. Wyn to begin a new paperback publishing company. Wyn was already a well-established publisher of books and pulp magazines under the name A. A. Wyn's Magazine Publishers.cite book | first=Donald H. | last=Tuck |authorlink= Donald H. Tuck| title=The Encyclopedia of Science Fiction and Fantasy: Volume 2| publisher=Advent: Publishers, Inc. | location=Chicago | year=1978 | pages = 471|id=ISBN 0-911682-22-8] His magazines included "Ace Mystery" and "Ace Sports", [cite web | url = http://www.philsp.com/data/data002.html | title = Magazine Data File|accessmonthday=11 May |accessyear = 2006] and it is perhaps from these titles that Ace Books got its name. Wyn liked Wollheim's idea but delayed for several months; meanwhile, Wollheim was applying for other jobs, including assistant editor at Pyramid Books. Pyramid mistakenly called Wyn's wife Rose for a reference, thinking Wollheim had worked for her. When Rose told her husband that Wollheim was applying for another job, Wyn made up his mind: he hired Wollheim immediately as an editor.cite book | first=Damon | last=Knight | authorlink= Damon Knight|title=The Futurians | publisher=John Day | location=New York | year=1977 | pages = 130]

The first book published by Ace was a pair of mysteries bound "dos-à-dos": Keith Vining's "Too Hot for Hell", backed with Samuel W. Taylor's "The Grinning Gismo", priced at 35 cents, with serial number D-01. A "dos-à-dos" book has the two titles bound upside-down with respect to each other, so that there are two front covers and the two texts meet in the middle (sometimes with advertising pages in between). This format is generally regarded as an innovation of Ace's; it was not, but since Ace published hundreds of titles bound this way over the next twenty-one years, it became the best-known publisher using the format. Books by established authors were often bound with those by lesser-known writers, on the premise that this would help new writers gain readers. The main drawback of the "Ace Double" format was that the two books had to fit a fixed page length (usually totalling between 256 and 320 low-height pages); thus one or both novels might be cut or revised to fit. Despite the tag "Complete and Unabridged" on the cover, books so labeled were sometimes still abridged. [cite book | last= Corrick| first= James A.| authorlink= James A. Corrick| title= Double Your Pleasure: the ACE SF Double| year= 1989 | publisher= Gryphon Books| location= New York| | pages= 11|id = ISBN 0-936071-13-3]

Some important titles in the early D-series novels are D-15, which features William S. Burroughs's first novel, "Junkie" (written under the pseudonym "William Lee"), and many novels by Philip K. Dick, Robert Bloch, Harlan Ellison, Harry Whittington, and Louis L'Amour, including those written under his pseudonym "Jim Mayo".Canja, Jeff. (2002) "Collectable Paperback Books, Second Edition", East Lansing, MI: Glenmoor Publishing. ISBN 0-9673639-5-0]

The last Ace Double in the first series was John T. Phillifent's "Life with Lancelot", backed with William Barton's "Hunting on Kunderer", issued August 1973 (serial #48245). Although Ace resumed using the "Ace Double" name in 1974, the books were arranged conventionally rather than "dos-à-dos". In 1988, the last Ace Double was released. All told, Ace published nearly 650 doubles, more than 600 of which were in "dos-à-dos" format.

1950s and 1960s: genre specialization

Ace's second title was a western (also "dos-à-dos"): William Colt MacDonald's "Bad Man's Return", bound with J. Edward Leithead's "Bloody Hoofs". Mysteries and westerns alternated regularly for the first thirty titles, with a few books not in either genre, such as P. G. Wodehouse's "Quick Service", bound with his "The Code of the Woosters". In 1953, A.E. van Vogt's "The World of Null-A", bound with his "The Universe Maker", appeared; this was Ace's first foray into science fiction. (Earlier in 1953, Ace had released Theodore S. Drachman's "Cry Plague!", with a plot that could be regarded as sf, but the book it was bound with — Leslie Edgley's "The Judas Goat" — was not sf.) Another sf double followed later in 1953, and sf rapidly established itself, alongside westerns and mysteries, as an important part of Ace's business. By 1955, the company released more sf titles each year than in either of the other two genres, and from 1961 onward, sf titles outnumbered mysteries and westerns combined. Ace also published a number of lurid juvenile delinquent novels in the 1950s that are now very collectible, such as D-343, "The Young Wolves" by Edward De Roo and D-378, "Out For Kicks" by Wilene Shaw.

Soon after the van Vogt Double came Dorothy Malone's "Cookbook for Beginners", the first title not in "dos-à-dos" format. Single novels appeared frequently beginning in 1954; initially, they were mostly books outside Ace's three main genres. By the 1960s, however, the core genres were also published as singles. The letter-series system seemed to indicate this change: the F and M series singles were overwhelmingly science fiction, but singles in the original D/G/S series, and the K series singles, were mostly outside the core genres.

By the late 1950s, Ace's output was approaching one hundred titles a year, still heavily dominated by the primary genres. Almost all the books were 35 cents, though some slim single volumes were 25 cents, and a handful were half a dollar. In the early '60s, rising costs finally forced an increase in the price of the books, and more books appeared at 40 cents, 45 cents and higher. A few thick volumes, such as the 1967 paperback of Frank Herbert's "Dune", were priced at 95 cents. The company now published scores of books in other genres, including many "nurse romances" (beginning in 1960 with Joan Sargent's "Cruise Nurse" bound with "Calling Dr. Merriman" by Margaret Howe). By the end of the decade, Ace produced perhaps 70 more such titles, along with gothic novels, self-improvement books, "strange but true" books, and many others.

Leader in science fiction

With Ballantine Books, Ace was the dominant science fiction paperback publisher in the 1950s and '60s. Other publishers followed their lead, catering to the increasing audience for sf, but none matched the influence of either company. [cite book|editor= Clute, John & Nicholls, Peter| title= The Encyclopedia of Science Fiction| origdate= 1993| publisher= St. Martin's Press, Inc.| location= New York| pages= 977]

Market dominance was not only reflected in numbers of books published — Ace published the first novels of several noted science fiction authors during this period. They include:
* Philip K. Dick's "Solar Lottery" (1955, D-103, bound with Leigh Brackett's "The Big Jump");
* Gordon R. Dickson's "Alien from Arcturus" (1956, D-139, bound with Nick Boddie Williams' "The Atom Curtain");
* Samuel R. Delany's "The Jewels of Aptor" (1962, F-173, bound with James White's "Second Ending");
* Ursula K. Le Guin's "Rocannon's World" (1966, G-574, bound with Avram Davidson's "The Kar-Chee Reign");
* Roger Zelazny's "This Immortal" (1966, F-393);
* R. A. Lafferty's "Past Master" (1968, H-54).

Ace published much early work of other prominent authors, including John Brunner, Thomas M. Disch, and Robert Silverberg.

Mid-1960s

In 1964, science fiction author Terry Carr joined the company, and in 1968, he initiated the Ace Science Fiction Specials line, publishing critically-acclaimed original novels by such authors as Alexei Panshin, R. A. Lafferty, Joanna Russ and Ursula Le Guin. During the mid-to-late 1960s, Ace also obtained licenses to publish original novels based on several popular television series of the day, most notably some two-dozen "The Man from U.N.C.L.E." volumes and a trilogy based on "The Prisoner".

Carr and Wollheim also co-edited an annual "Year's Best Science Fiction" anthology series; and Carr also edited "Universe", a well-received original anthology series. "Universe" was initially published by Ace, although when Carr left in 1971 the series moved elsewhere.

In 1965, Wollheim argued that there was a copyright loophole in the American edition of "The Lord of the Rings" by J. R. R. Tolkien. The Houghton Mifflin edition had been bound using pages printed in the United Kingdom for the George Allen & Unwin edition, and as a result, U.S. copyright law might not protect the text. Based on this view, Ace Books published the first-ever paperback edition of Tolkien's work, featuring cover art and hand-drawn title pages by Jack Gaughan. After considerable controversy and the release of a competitive authorized (and revised) edition by Ballantine Books (the back covers of which included a message from Tolkien urging consumers to buy the Ballantine edition and boycott any "unauthorized" versions — referring directly to the Ace editions),cite book |first=J.R.R. |last=Tolkien|authorlink= J.R.R. Tolkien| title=The Lord of the Rings| publisher=Ballantine |location=New York |year = 1965|pages=12] Ace agreed to pay royalties to Tolkien and let its still-popular edition go out of print.

Wyn died in 1967, and the company grew financially overextended, failing to pay its authors reliably. Without money to pay the signing bonus, Wollheim was unwilling to send signed contracts to authors. On at least one occasion, a book without a valid contract went to the printer, and Wollheim later found out that the author, who was owed $3,000 by Ace, was reduced to picking fruit for a living.cite book | first=Damon | last=Knight |authorlink= Damon Knight| title=The Futurians | publisher=John Day | location=New York | year=1977 | pages = 176]

Both Wollheim and Carr left Ace in 1971. Wollheim had made plans to launch a separate paperback house, and in cooperation with New American Library, he proceeded to set up DAW Books. Carr became a freelance editor; both Carr and Wollheim went on to edit competing Year's Best Science Fiction anthology series.

Ace as a subsidiary

By the early 1970s Ace Books was a major Division of the old publishing company, Charter Communications Inc., which was based out of the Hippodrome Building, 1120 Avenue of the Americas, in New York City. [Ace Star SF paperback edition, title page of "When the Sleeper Wakes", by H. G. Wells, book catalog #441-88091-075, ca. 1971]

In 1972, Ace was acquired by Grosset & Dunlap, and in 1982, Grosset & Dunlap was in turn acquired by G.P. Putnam's Sons. Ace was reputedly the only profitable element of the Grosset & Dunlap empire by this time.cite web | author=Bloom, Jeremy| year=1999| title=Chicon 2000:Editor Guest of Honor: Jim Baen | work=An Interview with the Editor Guest of Honor, Jim Baen| url=http://www.chicon.org/gohs/baen.htm | accessmonthday=10 May | accessyear = 2006] [cite web |title=Penguin Group (USA): About Us: History| url=http://us.penguingroup.com/static/html/aboutus/history.html | accessmonthday=10 May | accessyear = 2006] Ace soon became the science fiction imprint of their parent company.cite web |title=Penguin Group (USA): About Us: Ace Books| url=http://us.penguingroup.com/static/html/aboutus/adult/ace.html|accessmonthday=10 May |accessyear = 2006] In the late 1970s and early 1980s, Grosset & Dunlap operated an imprint called Ace Charter Books, which published mystery fiction such as reprints of the "The Saint" series by Leslie Charteris.

Carr returned to Ace Books in 1984 as a freelance editor, [cite book|editor= Clute, John & Nicholls, Peter| title= The Encyclopedia of Science Fiction| origdate= 1993| publisher= St. Martin's Press, Inc.| location= New York| pages= 199] launching a new series of Ace Specials devoted entirely to first novels. This series was even more successful than the first: it included, in 1984 alone, William Gibson's "Neuromancer", Kim Stanley Robinson's "The Wild Shore", Lucius Shepard's "Green Eyes", and Michael Swanwick's "In the Drift". All were first novels by authors now regarded as major figures in the sf genre.

Other prominent sf publishing figures who have worked at Ace include Tom Doherty, who left to start Tor Books, and Jim Baen, who left to work at Tor and who eventually founded Baen Books. Writers who have worked at Ace include Frederik Pohl, Ellen Kushner, and Laura Anne Gilman.

In 1996, Penguin Group (USA) acquired the Putnam Berkley Group, and has retained Ace as their sf imprint. Ace's 2006 list includes Julian May, Patricia McKillip, and Sharon Shinn, [cite web |title=Locus Online: New Books, 2nd Week February 2006| url=http://www.locusmag.com/2006/Monitor/Books02b.html| accessmonthday=11 May | accessyear = 2006] [cite web |title=Locus Online: New Books, 2nd Week March 2006| url=http://www.locusmag.com/2006/Monitor/Books03b.html| accessmonthday=11 May | accessyear = 2006] [cite web |title=Locus Online: New in Paperback: April 2006 | url=http://www.locusmag.com/2006/Monitor/NewInPaperback04.html|accessmonthday=11 May |accessyear = 2006] with books from writers such as Alastair Reynolds, Charles Stross, Jack McDevitt and Joe Haldeman planned for the remainder of the year.

Ace Books titles

Ace titles are frequently collected, both for their covers and for their affiliation with individual genres. Many individual titles are now highly sought after. Much of Philip K. Dick's early work appeared in Ace editions, and is now difficult to find in good condition. Among the rarest Ace titles are:
* William Burroughs (as William Lee) "Junkie" (1955, D-015, bound with Maurice Helbrand's "Narcotic Agent") [Near-fine copy priced at $1,000 located in second-hand bookstore cite web | url = http://www.heritagebookshop.com/ | title = Heritage Book Shop, Inc. | accessmonthday=14 August | accessyear = 2006]

The doubles format in itself has proved particularly attractive to collectors, with specialist reference works created for both the mystery and sf books, listing only the doubles. Several of these works are listed at the end of the reference section below. The following articles provide lists of all the Ace titles, organized by genre and by format (i.e., "dos-à-dos" vs. normal format).
* Science fiction: SF Doubles, SF Letter-Series Singles, SF Numeric-Series Singles; (SF)
* Mysteries: Mystery Doubles, Mystery Letter-Series Singles, Mystery Numeric-Series Singles; (MY)
* Westerns: Western Doubles, Western Letter-Series Singles, Western Numeric-Series Singles; (WE)
* Other genres: Doubles, Letter-Series Singles, Numeric-Series Singles; (NA)
* Combined-genre lists: all Ace Doubles volumes; all Ace Singles volumes.

The following lists give the individual series titles, for all genres.
* D/G/S-series — 599 volumes;
* G-series — about 266 volumes;
* F-series — about 330 volumes;
* M-series — about 66 volumes;
* H-series — about 108 volumes;
* K-series — about 207 volumes;
* A-series — probably 30 volumes;
* N-series — 4 volumes;
* Numbered series — over 1,000 volumes listed; many more are not included.

erial numbers

Ace titles have had two main types of serial numbers: letter series, such as "D-31" and "H-77", and numeric, such as "10293" and "15697". The letters were used to indicate a price. The following is a list of series with their date ranges and prices.
* D-series — 35¢, 1952 to 1965.
* S-series — 25¢, 1954 to 1958.
* T-series — 40¢. This series is listed in Tuck's Encyclopedia, [cite book | first=Donald H. | last=Tuck |authorlink= Donald H. Tuck| title=The Encyclopedia of Science Fiction and Fantasy: Volume 3| publisher=Advent: Publishers, Inc. | location=Chicago | year=1982 | pages = 715|id=ISBN 0-911682-26-0] but he gives no examples in his index and there are none cited in other bibliographic sources. This series may therefore not exist.
* F-series — 40¢, 1960 to 1967.
* M-series — 45¢, 1964 to 1966.
* G-series — 50¢, 1958 to 1960 (D/S/G series); 1964 to 1968 (later series).
* K-series — 50¢, 1959 to 1968.
* H-series — 60¢, 1965 or 1966 to 1968.
* A-series — 75¢, 1965 to 1968.
* N-series — 95¢, 1965 to 1968.

The first series of Ace books began in 1952 with D-01, a western in "dos-à-dos" format: Keith Vining's "Too Hot for Hell" backed with Samuel W. Taylor's "The Grinning Gismo". That series continued until D-599, Patricia Libby's "Winged Victory for Nurse Kerry", but the series also included several G and S serial numbers, depending on the price. The D and S did not indicate "Double" (i.e., "dos-à-dos") or "Single"; there are D-series titles that are not "dos-à-dos", although none of the "dos-à-dos" titles have an S serial number.

Towards the end of this initial series, the F series began (at a new price), and thereafter there were always several different letter series in publication simultaneously. The D and S prefixes did not appear again after the first series, but the G prefix acquired its own series starting with G-501. Hence the eight earlier G-series titles can be considered part of a different series to the G-series proper. All series after the first kept independent numbering systems, starting at 1 or 101.

In January 1969, Ace switched to a numeric coding system. The code depended on the title of the book: specifically, on the first significant word in the title. For example, Tom Purdom's "The Barons of Behavior" was published by Ace in about 1972 as serial number 04760. The first letter of "Barons" is "B", so the code assigned is fairly early in the numeric range 00000 to 99999. This procedure for assigning numeric codes was in use at Ace at least into the early 1990s, and may still be in use today. For Ace Doubles, one of the titles was selected and used to determine what serial number would be used. For example, 11560 is the Ace Double "The Communipaths" by Suzette Haden Elgin, backed with Louis Trimble's "The Noblest Experiment in the Galaxy". The serial number here is derived from "The Communipaths"; a serial number derived from the Trimble would have been about 58000.

For the later numeric series titles, the number is also part of the ISBN. To form the ISBN (if it exists) for one of these books, one prefixes to the serial number "0" (representing the English language/US), and "441" (Ace's publisher number). The last digit can then be calculated with an ISBN check digit calculator. For example, Christopher Stasheff's "Escape Velocity" has serial number 21599; the ISBN is 0-441-21599-8.
