Query: not a good reference book

This book is full of information with diagrams and drawings scattered throughout the text. There are graphs and calculations that are presented in each chapter for the various loads and gradients that can be calculated. But, Good Luck finding anything! The book is extremely vague and should merely be used as a reading book if you're bored and really enjoy learning about building envelopes. BUt if you need to look up an equation or theory, don't turn to the index, it won't be listed there along with the numerous other omissions that aren't listed which made this book incredible hard to use and reference.
