I have an advance copy of this book which is available for pre-order right now, for a February 5th 2013 release date. I am glad I have a copy as after reading it through I really do feel it is a great resource to have on your shelves.
The book is an updated, English language, US focused, version of a German book - which lists pretty much every food (and not just food) additive / ingredient available, and shows the source of each - you can see at a glance whether the ingredient is from an animal, plant, mineral, or if it is synthetic or microbial. Where varying sources exist these are all noted - enabling the individual to make the call as to whether they will contact the manufacturer for more information, or decide to consume or otherwise.
The introductory sections are short and provide a brief how-to of the book, however there are extensive sections at the back of the book which look at issues such as product labelling (Part 2), touch on vegan alternatives (Part 3) and supply a resource section (Part 4). The book is very much a reference book, and does read a little like a text book you'd have from school, but really, that is what it is so the tone and style is appropriate.
The book is full of information which is handy to both new and "older" vegans so is suitable for all! One caveat though, reading through you do get an overwhelming sensation of how pervasive animal ingredients are in every single part of modern life, and this could be a little depressing for some people - and as the book is written as a reference book there is not a balance of "do what you can as you can" or "control what you can control and don't beat yourself up over what you can't" type statements, which I personally feel every vegan needs to bear in mind so as not to become completely discouraged. I do believe that the little steps everyone takes every day do make a difference, and that used in the manner it is written, this book will enable more people to make those little differences which add up to big differences.
