It basically elaborates more in depth what's on the website, but it also brings up more information from around the world. I don't quite understand exactly the whole meaning behind the the book as to why everything points to Sirius. So if you buy this book expecting an explanation you aren't going to get it.

The key piece for me, the part that makes the book interesting, is the author's approach to explaining why things have developed the way they have. As described I don't necessarily agree with the author, but the book is likely worth a read just to better understand his reasoning.

I'm using this book already, borrowed from a friend... and I had decided to buy it just because when I read a good book I want to own it. Its clear, with a lot of exercises, just lack the answers (important factor for those  that aren't quite well familiar with english) but, in overall it's a  valuable book and helpfull to learn english
