This is not a bad book. There is valuable information in there for anybody interested in doing e-commerce.
The problem with this book is that you have to go through so much agony to actually find the information. It is 764 pages long and could have been really great if a good editor had cut it down to half.
As it is, you have to sift through so much irrelevant content that you will struggle to turn each page and this actually hinders the level of understanding of all the good stuff.
As another reviewer writes, there is just way too much of "this was covered in section X" og "this will be covered in section Y". Too many trying-to-be-pedagogical excersises. Way too many unnecessary words. This book just needs to get to the point.
Add to this that the language is very poor. The book has the feel of an over-ambitious MA thesis with so many references and cross references and so much dreary language that it will make you consider whether you want to get into the world of e-commerce at all.
Finally, it is in dire need of an update. You will find heaps of case studies from the nineties! Yes, nineties. This is more than a decade ago, and a decade in internet-time is the same as a century. Here and there you will find an extremely brief (a few lines) "update" to what has happened between 1999-2010. Say you are looking for something as basic in 2011 as using Facebook in an e-busines context. Forget about it.
As for now, it's two stars from me. But with some hefty editing, updating and spicing up of the language, this could actually be a really valuable book. Maybe the 2011 edition will offer some of that.
