Notes: This publication is not a reprint of the original collection; it only contains the novel The Moon Maid. Tuck shows this publication as published in 1963 under the Burroughs entry, but shows it published in 1962 under the Ace entry. Library of Congress information also claims 1962. Currey, Reginald and Clute all have 1962. Cover art and title-page illustration by Roy Krenkel, Jr. on copyright page, interior piece has the initials RGK Edgar Rice Burroughs: The Descriptive Bibliography of Ace and Ballantine / Del Rey Paperback Books lists two variants at different addresses which may explain the date differences. This publication has the address 1120 Avenue of the Americas. Hence the 1963 date was used.
