This book is a treasure trove for anyone interested in SC. The writing style throughout is accessible and enthusiastic, and the quality of information is truly impressive. Of course, any book like this one suffers from the rapid pace of software development, so some information is already outdated. However, as far as I can tell all the examples are useful as-is (barring system-specific dependencies). The book is not organized as a progressive series of tutorials, so the newcomer may seem a bit bewildered by the array of SC's possibilities and how best to go about learning them. I suggest the complete beginner read Cottle chapter to get started, then just jump into the other chapters as they become of interest.
I've used SC with Linux on & off over the past years. The SC Book has been a great inspiration for me to get back into this wonderful language - I'm primarily a Csound-based composer, but I'm always on the look-out for interesting developments in similar languages and systems. Btw, the only reason I didn't give it five stars is the absence of an accompanying disc, but in truth it isn't necessary, the book will guide you to all necessary resources. So okay, I'm really giving it four and a half stars. :)
