Query: Book poorly written 3rd edition

Many of the example problems take short cuts while trying to explain the material through practical problems. When reading the book one is forced to constantly, turn the pages backward for previous references in order to understand the short cuts. The book is in need of some serious editing. Nevertheless, not all engineering books get better with editing. Spotts, machine design, for example in the 6th edition is a Great Book! In the 8th edition, it is useless. This book has the potential to be a good textbook. However, in this form it is just about 3 pounds of paper and cardboard with a fancy cover. Not the worst textbook ever, but it made the list.
