No record credits, but these adventures were fairly consistent with the TV show and the more recent(at the time) animated one. The cover and back cover are by Neal Adams, with the interior art by Russ Heath(!), with inks by Dick Giordano and Adams.
Clearly someone lost the character reference file along the way, since Sulu is drawn as African-American, and Uhura is colored caucasion. Anybody over at Peter Pan ever see Star Trek?
