Going one way, the book would have to be either “The Way Things Work” or the Boy Scout Handbook.
Going the other way, I’d have to agree with Edwardina and go with the Bible.
As for a CD, either Sgt. Pepper or Abbey Road.
CD = This Desert Life - Counting Crows - it’s just the most fun to sing along with
Book = Moviehound Golden Movie Retriever 2000 - the book I use the most. Of course, how often are movie trivia questions going to come up on a deserted island?
Book: Infinite Jest–David Foster Wallace
CD: Thunder Perfect Mind–Current 93
The Boy Scout Handbook is an excellent choice; just about everything you’d need to know would be in there.
