Query: One of the WORST books I've ever read.

I made the mistake of purchasing this book at a local book store as I needed an AIX book that day and they only had 2 books.This book looked to be more useful than the other book but as soon as I started reading it I found out how bad it was.Much of this book is woefully antiquated and unfortunately much of it has AIX version 3 information instead of 4.I read the book from cover to cover as I needed to get as much AIX knowledge as I could that day and I can tell you that I learned about 4 things from the book that would be useful. The rest of the book had information that has little to no bearing on administering a system or applies to a version 3 system and not AIX 4.X.Please DO NOT BUY THIS BOOK AS YOU WILL BE VERY DISAPPOINTED IN IT!
