There has been much written and said regarding electronic commerce but few books describe principles quite so accurately and in such a useful manner. I use this book for reference and instruction, and the historical content is actually a lot more interesting than I ever gave it credit for. There are very useful case studies which are thoughtfully distributed throughout and serve to re-inforce the dialog well. In short, if you want to learn about electronic commerce buy a copy and if you work in electronic commerce (as I do) then buy a copy and keep it in your desk.
