Ace Double F-129 (40 cent cover price) 1962 paperback. Condition is VG+ to near-Fine: tight and square with flat spine; faint line near bottom of "3 Suns" side faint vertical scuff in top middle of "Goliath" side - both of these faults are minor enough that they tend to get lost in the artwork (and may not show up on the scans.) Age tanning is mild and uniform; no stamps or writing.

Ace Double F-129 (1962): The Automated Goliath, bound with The Three Suns of Amara - both sides by William F. Temple. The "3 Suns" side was reprinted as half of another Ace Double in 1973 (also with both sides by Temple); the other can only be found here.

The Automated Goliath - Cover by Ed Emshwiller (?); 143 pages. This is an expansion of "Against Goliath" from Nebula August 1957. The age of automation had brought leisure and luxury to Earth. It also made it vulnerable to a group of migratory aliens - the Makkees - who were able to subvert the automated industrial network to their uses.
