If you like Star Trek: The Original Series, this is pretty much the book you want to get if you need a reference work about it. The book has been lovingly crafted by one of the original Trekkies and covers ALL of the original series, the animated series, and the movies. It also has most of the TOS cast appearances in the other Trek franchise shows (missing only “Trials and Tribblations” from DS9). Each episode is synopsized, and then there are several encyclopedic sections on terminology, starships, planets, and a list of actors and actresses from the program. The first and still the best print resource on the original Star Trek!
