It was first published in hardcover by Robert Hale in February 1977 in the United Kingdom, with an American hardcover edition following from St. Martin's Press in June of the same year, and a paperback edition from Jove/HBJ in June 1978.

[1] John Clute considered the collection a "jalopy of a book," an "atrocious little money-spinner," whose contents could not have "required more than a modicum of research to uncover."

Of the editor, he wrote "In general his editorial comments are among the most illiterate ever printed, with high-school syntax howlers and unintended neologisms breeding together ... like fruit flies in Hiroshima, nor on decipherment is what he says about his assemblage of stories even interestingly false."

He singled out for particular praise del Rey's "Helen O'Loy," "that famous crazy comedy romp."

The other tales he lumped together as "warhorses," with the exception of the Aldiss piece, which he neglected to mention.
