Ace was above all a paperback house. Many Ace books reprint hardbacks from other publishers, but much of its science fiction appeared first as Ace paperbacks, and for those titles the first Ace printing is the true first edition. Junkie (1953), Rocannon's World (1966), Babel-17 (1966) and Neuromancer (July 1984) all came out first as Ace paperbacks; Neuromancer first appeared in hardback from Gollancz in London later in 1984.

We have not yet confirmed the issue points that tell this first impression from later ones. Until we do, compare your copy's title page and copyright page with the publisher, place and year above: any later printing or edition statement means it is not this one.
