There's always lots of enthusiasm for these books. I have 1-3 (well 3 has been with Nug for ever, might get it back one day). While they are a great source of information and pictures, the writing style left me just looking at the pics and captions. Not sure if these are self-edited, but they sure could have done with some input. That did put me off buying 4 (and truthfully my wife bought me the other 3!!)
