An observation (Maybe somebody else has made it already) about ST fiction:
From the first airing of "The Man Trap" in the Fall of 1967, through the Fall of 1977, a period of a little over a decade, there were 27 volumes of officially licensed and sanctioned Star Trek prose fiction published, the combined output of three publishers. 21 of those volumes were books of episode adaptations (TOS by Blish, TAS by ADF), one of which was an anthology consisting mostly or entirely of works that had already been published in fanzines, and one of which was a children's novel.
By the time the last Bantam and Ballantine ST books went out the door (including two more volumes of episode adaptations, one of which included an original novella, a movie novelization, and another mostly-fanfic anthology), there were 40 volumes of Star Trek prose fiction in existence.
At the peak of Pocket's Star Trek output, a time that coincided with a period when there was always at least one Star Trek series in first run on commercial television, and "Prime Universe" Star Trek feature films were being produced on a regular basis, the average annual Star Trek output of Pocket Books alone was at least as many volumes of ST prose fiction as existed in the fall of 1977. Much of this was horseshit, bad enough that, at least according to legend, Roddenberry read some of it, and sicced Richard Arnold on the world. And yet even the worst of the horseshit wasn't nearly as bad, either in terms of Roddenberry's vision or simply in terms of general literary merit, as the worst of the Bantam ST novels. And that period also produced such undisputed masterpieces as Diane Duane's Spock's World.
We have quite literally hundreds of extant volumes of Star Trek prose fiction to choose from, covering all the series that ever appeared on television, and series that exist entirely in print. Even if we leave the horseshit on the shelves, we could read two or three of them each week, for several years, and not run out.
And it's not like there isn't other fiction out there. Some of it is better than any Star Trek novel ever written, and some of it (like a certain novel about the Chinese attempting to discredit the Apollo Moon Landings, that somehow grew two sequels in spite of being so unspeakably bad that I will not sully this Board by invoking its title) makes even the three worst Star Trek novels ever published look good by comparison.
