List of Ace SF numeric-series single titles

Ace Books have published hundreds of science fiction titles, starting in 1953. Many of these were Ace Doubles (dos-à-dos format), but they also published many single volumes. Between 1953 and 1968, the books had a letter-series identifier; after that date they were given five digit numeric serial numbers. There are 693 numeric-series sf titles in the list below, but the list is very incomplete.

The list given here gives a date of publication; in all cases this refers to the date of publication by Ace, and not the date of original publication of the novels. For more information about the history of these titles, see Ace Books, which includes a discussion of the serial numbering conventions used and an explanation of the letter-code system.
