Review title: Useful as a guide for two people only: The Authors!
Product review: Don't waste your bucks or quid on this weighty tome, use allmusic.com or iTunes instead. Due to the two author concept, this rather opinionated effort (and the authors must be commended for a very big effort) is nothing more than the jazz opinion of two guys. They show little empathy for musicians they don't care for, and omit many who they do not classify as "true jazz" (whatever that might be.) At least allmusic has a team of reviewers who are sympathetic to the musicians they happen to be writing about. What's more, allmusic doesn't take the slightly smarmy approach that these two do. Forget it.
