A reviewer on Amazon said that is the worst technical book in any field he 
has ever seen.  I agree.  It has lots of information, but it is not 
presented in a logical fashion, so it is nearly impossible to learn from, 
if you are starting from scratch.  IOW, the early material assumes you 
already know the later material, etc.  I've ended up using the 
manufacturer's data sheets whenever I use a PIC.
