Franz Joseph Schnaubelt's impressive work in the 1970s was (and still is) inspiring and insightful. He engrained many interesting ideas into STAR TREK lore. He was a pioneer, adding a new dimension to TREK terminology, literature and art. I don't think anybody else was doing anything like that before he did.
That having been said, the pioneering nature of his work also made it quirky from our vantage-point. He did all that at a time long before VCR's, the consumerized internet, or even the Web. There was no on-demand video viewing, no freeze-frame, no downloadable transcripts or anything like that. It was like listening to a radio show; as soon as it is said, it is gone ("the mysterious medium"). FJ's fixation on "Whom Gods Destroy" is an excellent example: from Kirk's conversations with Garth, FJ derived that the Federation wasn't officially organized as a working entity until James T. Kirk was a young man at the Axanar Peace Conference. (Strangely, Kirk and Garth alluded to a battle at Axanar, with Garth's command abilities apparently tested in that battle; plus Kirk was said to be a cadet or young officer at Axanar. In order for this to be the case, there had to be some organization of planets, plus some space armada, already in existence prior to the Federation. Could it be Archer's Coalition of Planets???) Other mentions of Federation history muddy the waters, like the Starships Horizon and Archon having been lost 100 years prior to TOS, were never mentioned in FJ's work. So it could be said that some things were either very loosely interpreted or just plain "fell through the cracks" of FJ's records.
