Negative Retouching and Print Finishing Book

I've been wanting to learn more about spotting LF b&w negatives so I put in a bid on a retouching book on ebay. I was just notified that I won the auction and was wandering if anyone had ever heard of the book and what they thought of it. The book is "Negative Retouching and Print Finishing" by Draper and Harkness.
