How to Identify a Ace Books First Edition

US · 1952–present

The fastest check: 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.

How to identify a first printing

Decode the printer's key: paste the number line into the number-line decoder, search any title in the First Edition Checker, or run a book through the identifier.

Notable points & cautions

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).
