Query: This book is USELESS

This is the most useless reference manual I ever read. I wanted to just write a simple Latex document with a few tables and a couple of embedded graphics. This book was so inadequate that I found myself going to the web resources repeatedly. I believe the point of writing a reference book is to provide a compilation of enough information so the readers don't have to go fishing for information for themselves. In that regard, the author failed miserably.A book of this size should be a simple tutorial book. There's not enough content to serve any use as a reference book. Very Disappointed!
