I found this book unwieldy in it's size (1154 pages including the index and appendices) and not very helpful for the beginning admin, which is all of us, including IBM!! There are hundreds, if not thousands, of screenshots, but very little in the way of explanation. I need a book that addesses the tasks I most need to do as a WebSphere Admin, with explanations as to why and how to do them. I have found that IBM's online Infocenter for WebSphere is the best resource for this. Bottom line: As a WAS admin you should have this book, but Infocenter may be more helpful.
