And The Making of Star Trek, Star Trek Lives! and a rolled tube containing the D-7 blueprints purchased at a convention in 1976.
From about 1970 through 1982, I prided myself on owning "everything there was," starting with TMOST and James Blish (every numbered volume plus Spock Must Die!), the manuals and blueprints (FJ and Michael McMaster), non-fiction books about the show, every issue of Star Trek Giant Poster Book, and whatever else, all the way to the TWOK-era Pocketbook novels. Then I was forced to start discriminating because there were too many novels and I wasn't liking all of them.
During the Internet era, it would turn out that I'd missed something: Mission to Horatius. I just never knew it existed.
