Notes:
-- This version is not a new edition, but a reissue (with a new set of printings) of the Bullseye Edition with different cover art. Both share the same ISBN and printing plates (typeface). Technically, this issue should be included with the Bullseye Edition, but was given a separate section because it was part of a recent Random House release of the first eleven books in the series with renewed copyrights.
