This text is amazingly useful, and as a text alone, I would give it a 5-star rating. I purchased it on Kindle, realized I needed a paper copy for my research, and bought the $9.99 "high quality paperback" version.However, this is literally the ugliest book in my house. It looks like it was constructed at Kinko's. I don't know quite what I was thinking here - perhaps that it was a placeholder icon instead of an actual version of the book. The cover actually does say "HIGH QUALITY PAPERBACK" and "AFFORDABLE AND HIGH QUALITY PAPERBACK BOOK EDITION", the spine is blank grey, the pages are not very firmly set, and the font is a faded Courier. Unless you are a college student who will never touch this text again after your class is over - please, please find a different edition.
