Query: Old not a good book

I'm disappointed in this book, its old and out dated. It doesn't really show how a pole building should be constructed and the materials needed to build one now, its based on the 80's. This book shows the use of timbers and older styles of building. If you're looking for a book to show you the way to build a pole building, what type of materials, and how to go about the set up of the concrete flooring this book is not what you're looking for.
