I don't have too much aside from the DVDs and box sets - although I've inherited a fair few books from my dad. Shatner and Nimoy autobiographies, TNG book about the bloopers and so on (can't recall fully as I haven't seen it for years!) and a great TOS anthology paperback. Must have been released in the early 90s as it had segments on all the films up to TFF.
Probably a pretty well known one to you lot, not sure of the title. Man, I loved that book. Had a picture of the cast from the 60s on the Enterprise bridge on the back. Think it may have had Kirk and Spock on the front.
