I think, such books are for those, who need to brush upon the "topic" covered within the least possible time...
I had read this in some preface where the author of Teach Yourself <whatever> in <so many hours> mentioning that this book is for those whose boss has given them a new project and they have this "topic" in it..and they should know about it...
Therefore, I feel this book is good enough when u need to just revamp "topic" :-?
