Query: industrial control wiring guide

I was hugely dissapoited with this book from the second I removed it from it's shipping container! This very small pamphlet sized book looked as though it would only provide me with an evening of research. When I opened it, it proved to be an even greater dissapointment. Extreemly simplistic drawings of subjects such as how to mount a relay on a track, how to strip wire, and how to tie knots, very unsubstantial text. I would not recomend this book to anyone, It is just too basic. Even the title is deceptive, I only found one control wiring diagram of a basic start/stop circuit. I am going to return my copy!
