Background information 
 Like many of the releases in this series, some, but not all, of the stories in this volume were based on early draft scripts, which explains why there are some significant differences between the printed version and what actually appeared on screen. Due to the lead times required for publication, Blish was forced to use the scripts available from Desilu and Paramount Pictures promotions, some of which were draft scripts that had been discarded, while others were actual filming scripts. After this volume, the series had finished its run, and filming scripts were available. This is reflected in the increased accuracy of the adaptations in the remaining volumes of this book series.
