Premise 
Key Collection Volume 3 was a  paperback collecting the third set of issues from Gold Key Comics' original Star Trek monthly, spanning from  to . This was the third in the series of Star Trek: The Key Collection. It was similar to the original Enterprise Log 3, but dropped the final story.

It depicted the events of a later missions taking place during the TOS five-year mission. While no definitive timeline was established, the stardates of these stories match a range of stardates spanning approximately the last three-quarters of TOS Season 1. Several canon characters and concepts were included in the stories, but the details were very much contradictory with televised Star Trek of the era; the artists were apparently unfamiliar with the source material.
