How to identify a first printing
- Primary method (pre-1968): a first printing carries NO printing statement and NO later-printing line on the copyright page. Ace applied this inconsistently, so treat the absence of a printing notice as suggestive, not conclusive.
- Use the Ace serial/catalog number (letter-prefixed code, e.g. 'D-xxx', 'F-xxx', 'G-xxx', or post-1968 five-digit numeric like '12345') printed on cover/spine to date and place the edition. The LETTER prefix primarily encodes the cover PRICE and era (D=35c 1952-62, S=25c 1952-56, F=40c 1961-67, G=50c, M=45c, H=60c, A=75c, N=95c 1968), not strictly the printing order. Reprints were frequently reissued under a new/changed serial number at a higher price, so a higher price or changed prefix for the same title signals a later state.
- Caution on 'First Ace printing' / '1st Ace printing' wording: per Ace reference sources this phrase means the first time ACE published the title and IMPLIES a prior hardback or paperback edition exists elsewhere -- it is NOT evidence of a first edition of the work. Do not treat it as a true-first tell.
- Price increases on later printings of the same/related serial number are a reliable later-STATE indicator. There is no well-documented, consistent Ace convention of an explicit 'First Ace printing: <Month Year>' statement followed by a standard number line with '1' present; do not rely on a number line as the primary Ace first-printing test.
Notable points & cautions
- Founded 1952 by A. A. Wyn (Ace Magazine Company, New York); Donald A. Wollheim spearheaded the paperback list, added SF in 1953, and was the influential editor (~1952-1971) before founding DAW Books with Elsie Wollheim (named for his initials; first titles April 1972).
- Ace Doubles (1952-1973) bind two novels tete-beche (head-to-toe) with two front covers; first-printing identification keys on the serial number and price rather than a printing statement. The final D-series double appeared Aug 1973; post-1974 'Ace Doubles' were arranged conventionally.
- Ace Science Fiction Specials -- the acclaimed Terry Carr-edited first series (started 1967, into the early 1970s) -- are sought as paperback firsts (Le Guin, Lafferty, Russ). A second Specials series (1984) carried debut firsts such as Gibson's Neuromancer.
- Pre-1968 mass-market firsts rarely state anything on the copyright page, so the no-later-printing-line rule combined with the serial-number/price (and price-increase) tells is the main practical handle.
- Now an imprint of Penguin Random House, operating within the Berkley Publishing Group as its SF imprint (Berkley/Ace).

Frequently asked questions
How do I know if my Ace Books book is a first edition?
Check the copyright page. Primary method (pre-1968): a first printing carries NO printing statement and NO later-printing line on the copyright page. Ace applied this inconsistently, so treat the absence of a printing notice as suggestive, not conclusive. Use the Ace serial/catalog number (letter-prefixed code, e.g. 'D-xxx', 'F-xxx', 'G-xxx', or post-1968 five-digit numeric like '12345') printed on cover/spine to date and place the edition. The LETTER prefix primarily encodes the cover PRICE and era (D=35c 1952-62, S=25c 1952-56, F=40c 1961-67, G=50c, M=45c, H=60c, A=75c, N=95c 1968), not strictly the printing order. Reprints were frequently reissued under a new/changed serial number at a higher price, so a higher price or changed prefix for the same title signals a later state.
Does Ace Books use a number line?
Use the Ace serial/catalog number (letter-prefixed code, e.g. 'D-xxx', 'F-xxx', 'G-xxx', or post-1968 five-digit numeric like '12345') printed on cover/spine to date and place the edition. The LETTER prefix primarily encodes the cover PRICE and era (D=35c 1952-62, S=25c 1952-56, F=40c 1961-67, G=50c, M=45c, H=60c, A=75c, N=95c 1968), not strictly the printing order. Reprints were frequently reissued under a new/changed serial number at a higher price, so a higher price or changed prefix for the same title signals a later state.
Is a book-club edition a Ace Books first edition?
No. Book-club editions reprint the text but are not the true first edition. Founded 1952 by A. A. Wyn (Ace Magazine Company, New York); Donald A. Wollheim spearheaded the paperback list, added SF in 1953, and was the influential editor (~1952-1971) before founding DAW Books with Elsie Wollheim (named for his initials; first titles April 1972).
