Does anybody know, was there any sort of continuity at all to these early Trek novels? Did Bantam books do a lot of these? Are any of these worth any money?
It's worth picking up and sampling some Bantam novels to give yourself a perspective on what things were like in the 70s for ST fans.
When you say, "Are they worth money?" do you mean are they worth buying, or are they so rare as to be expensive as second hand copies?
They had incredibly long print runs, most going into many reprints and trialling numerous cover designs over the decades (one time even emulating then-current Pocket titles). By a quirk in Bantam's original contract, they are allowed to keep reprinting them
whenever they like, even though the license passed to Pocket Books.
So they are not that
hard to find, and should never be too expensive. Unless you're seeking minty first editions.
