The number of Star Trek stories ever published was derived as follows.
Included are all novels, novelizations, novellas, short stories, short novelizations, ebooks, young
adult novels, young adult novelizations, young adult short stories, children's books, children's novelizations, record adaptation novelizations, graphic novels, graphic novel adaptations, comics, comic adaptations, photostory adaptations, comic strip
arcs, comic stories, comic story adaptations, record story comic adaptations, record story short comic adaptations, audio dramas, audio drama adaptations, short audio drama adaptations, record adaptations, and short record stories.
Not included are audio drama scripts, game lore blog stories, reprints,
reference works, or children's toy based stories like coloring books and
Happy Meal boxes. I consider Star Trek: Khan to be a canon production,
and it is also not included here.
I have organized this list in two different methods: broken up by publisher-> series-> story type; and broken up only by series-> story type.
