I just noticed that one category of facts is missing: the relase dates of CD editions. I remember that I bought the newly released CD versions of Hot Rats, Weasels Ripped my Flesh, Sleep Dirt, Zappa In New York and Uncle Meat in the early 90's because there was stuff that was not released on the original LPs. It would be nice to see the exact release dates of those previously unreleased versions. This book does a great job analyzing all the differences between the CDs and LPs, even the tiny ones between different editions, but lists only two release dates of each album: 'original' and 'current'. But anyway, this is just nitpicking, the book is awesome!
