Notes:
Library of Congress (LCCN, below) reports "Harcourt Brace Jovanovich, [1990]" and (quoting the book; presumably the title leaf, punctuated by LC) "An Odyssey classic."

Supposing that the cover image is valid and interpreting the catalog record routinely, this publication shows that "Odyssey" (front cover banner, at least; perhaps publication series or imprint name) was replaced by or renamed as "Odyssey Classics" during the Jovanovich era; that is, prior to HBJ's succesion by or rename as publisher {{publisher|Harcourt Brace}}.
