This book's contents are good. I knew when I purchased it, that my copy was "used" but supposedly in "good" condition... Almost every page is underlined and marked up with highlighted text, underlined text, scribbled annotations.... Should have classified as simply as "readable" with difficulty... Very disappointed in this book's promotion...The book's content is good and has the high quality you expect of William Barry. Will probably try to purchase another copy which is "presentable"
