As a basic intro to composition and visual storytelling I really like this. It's seems super simple at first glance, but it's actually very dense, with a ton of information presented really well (kind of like a good composition). And, it's cheap!
a great book to look out for is Cyril Pearce's book Composition: An Analysis of the Principles of Pictorial Design, from 1912 or so. i'm fairly certain it's well out of print now but it's very comprehensive and worth looking out for. i found my copy in a skip along with loads of other fantastic books (including a master drawings one and a first print edition of a 19th Century book on drawing and engraving)
