"By Any Other Name" also mentions Eminiar VII, from "Taste of Armageddon." And "Turnabout Intruder" mentions Tholians, as well as Vians (from "The Empath"). And so on.
Not to mention all the effort they put into coming up with a coherent concept for how the ship's engines and power systems worked. (An effort that got taken to occasionally ludicrous extremes in the TNG era... but that's another story.) And, just in general, the effort to avoid having episodes contradict each other.
By way of contrast, western shows at the time (which were huge, and many Trek writers, cast, and crew had worked on them) were notoriously slapdash about continuity, to the point that even when they tried to inject a little "authenticity" by referencing bits of genuine history, they often did so with no regard for actual real-world chronology, jumping back and forth by years for the sake of a single story. Or take a more recent example, Detective John Munch, the "connective tissue" between Homicide and the Law & Order franchise... the writers over the years couldn't even keep straight whether he was born and raised in Baltimore or New York City.
I think a lot of contemporary viewers have an artificially and unjustifiably low view of original Star Trek, based on mistaken impressions and misinformation about what the show was actually like and how it was actually made. (And that's kind of odd, really, when you consider that it's probably one of the most well-documented productions in television history. People have no excuse!)

Maybe after another few discussions.
