That's one of my favorite books, but I loved both Star Trek and Here Come the Brides. It seems weird that I never saw Here Come the Brides in syndication.
My awareness of "Here Come the Brides" came from Joan Winston ("Star Trek Lives!" and "The Making of the Trek Convention"). She spent time on the sets with Trek alumni, David Soul, Robert Brown and Mark Lenard and wrote about it. I don't think I ever saw the actual series.
When "Ishmael" came out, I recognised the arrival of Hoss and Little Joe ("Bonanza") and immediately rang a "Bonanza" officianado - and she was the one to connect the dots with HCTB, based on my brief description, and thus greatly enhancing my appreciation of the rest of the novel.
