My life in outer space

Ace Doubles

“If the Holy Bible was printed as an Ace Double”, an editor once remarked, “it would be cut down to two 20,000-word halves with the Old Testament retitled as ‘Master of Chaos’ and the New Testament as ‘The Thing With Three Souls.’”

— Charles McGrath, New York Times, May 6, 2007


Ace ran their ‘doubles’ print from 1952 to the late 70s, although the tête-bêche format (in which these books contain two novels and have two front covers with a spine containing both titles) was discontinued in about 1973,
Originally, Ace published mysteries, Westerns, and the odd PG Wodehouse novel, but introduced SF and Fantasy in 1953.
Despite their reputation for ‘pulp fiction’ quality material (and it has to be said that many of the novels under this imprint are not of a high standard) there are some marvellous surprises to be found. Ace Doubles printed (or reprinted) the likes of Robert E Howard, Philip K Dick, John Brunner, Ursula LeGuin, Clifford Simak, Poul Anderson and Robert Silverberg, to name but a few. Because of the nature of the publication, the novels are of necessity short, and average around 40,000 words.
I love them for many reasons, not least the cover artwork and the over the top hyperbole of the cover comments and the blurbs, which more often than not was far removed from the actual content of the novels. (See the Charles McGrath quote above). They can still be found fairly cheaply online, although the older issues are becoming a little scarce.
Below is a list of the SF/fantasy titles (which I cannot guarantee is completely accurate. If you find any errors or omissions here, please let me know) with links to my review, where one has been posted. Titles were occasionally reprinted, sometimes with different pairings, so you will find titles duplicated in this listing.

  1. When I was like 12 a local used book store was going out of business and I bought like a dozen of these for a quarter,each I wish I still had them.

    • I bought quite a few from ‘The Fantasy Centre’ in Holloway Road that sadly is no longer with us. The days of used book shops are numbered I think, which is a terrible shame. I used to spend hours in them and found many of my now favourite novels on their shelves.
      Ace Doubles are still fairly accessible quite cheaply online though. is an excellent source.
