This is comprehensive and reasonably up-to-date, but I found it a disappointment. Too many times it skims over the detail which I hoped to find in a book of this type and this price. Especially annoying is when I go to verify something and find the only reference to be in one of the dozens of (unanswered) 'questions' that are gathered at the end of each chapter. I go to a book like this for answers, not questions. However I acknowledge that, in accordance with its title, it will help you to understand SIP; just don't expect much practical help for implementing, using or debugging it. I will keep it on the shelf, nevertheless.

This book may well be authoritative but I find it interesting I paid £44, but my book got "damaged in transit". It took weeks for the refund. Now interestingly the book is being sold at £105.This all seems a bit crooked!
