These are the episodes for which he shared a credit with another writer:
Bread and Circuses (with Gene L. Coon)
The Savage Curtain (with Arthur Heineman)
Encounter at Farpoint (with D.C. Fontana)
Hide and Q (with Maurice Hurley)
Datalore (with Robert Lewin)
The episodes listed uptopic which are not included here are those for which the teleplay is credited to other writers and Roddenberry received a sole or shared "story by" credit.
As I mentioned before, a "story" can be anything from a one or two sentence premise to several pages. With rare exceptions scene breakdowns, detailed action, dialogue and character development are inherent in the teleplay itself. The teleplay is the actual script, the blueprint from which the episode is budgeted and produced. WGA contracts establish much higher payments and percentages of residuals for the author(s) of teleplays than for those awarded story credit alone.
BTW, I searched using the list of episodes presented uptopic as my basis. Therefore, if there are episodes that Roddenberry was credited for that were not in that list I've missed them in mine as well.
Add to that, I think the larger point of that list was that the creme de la creme of Star Trek both in shows or films do not appear.
Gene may have had a vision of the show when he started it, but ultimately the very best of Star Trek was done by other people.
To this day I can't stand the glorification of Gene. He had a great idea for a TV show, and he had some good ideas about how life should be in the future (by-in-large) but he isn't responsible for the shows best work.
In some cases Trek's best moments came from people who were just doing a gig and were never Trek fans.
