Notes:
- Most likely, the fifth printing.
- The copyright page says: "Fourth Printing: May 1988" (of the 1987 Del Rey edition). However, the Feb. 1988 printing is also listed internally as the 4th printing. They probably updated the publication month for this printing, but neglected to update "Fourth" to "Fifth". (The seventh printing isn't until June 1990, so it is unlikely that this is actually a sixth printing.)
