Title Reference: The Fourth Hemisphere
Notes: Volume 2 in Void's "Australian SF & Fantasy" series. Info from Locus #235 (July 1980), and an Abebooks.com dealer listing. A page of advertising for Void hardcover books on the page after the last page of the novel, states that only 250 hardback copies of this novel were produced. Same ISBN as the softcover edition according to the Abebooks.com listing. Comparison of the hardback with the paperback shows that it appears to be copies of the paperback (minus the wraps) bound in black boards, as the page size is identical and the page content is identical, including the copyright page. The dust jacket flaps are blank, it does show slightly more of the cover art at the top and bottom, so it is not just a blow up of the paperback cover but is otherwise identical.
