Data from a hardcover with no jacket (cover art, etc. directly on the cover). Back Cover gives ISBN 0-385-90103-8; copyright page states ISBN 0-385-73081-0 (trade) - ISBN 0-385-90103-8 (lib. bdg.).
The Locus index gives only 0-385-73081-0 & states that it is a hc. It is thus unclear to which edition the price on Locus refers. (Amazon.com also lists 0-385-73081-0 as a hc.)
The Locus Index also has different spelling for the cover artist's first and last name. (Possibly typos in the Locus Index, because Merritt Dekle already has an entry in the ISFDB.)
