Query: Cut and paste job. This is not a text book.

Any college graduate can cut and paste published papers and create a massive "reference" work. There is no proof that the person who "wrote" this book is actually Dr. Sze. (Compare this with Feynman's "Lectures on Physics" where every paragraph is screaming "Mr. Feynman wrote this.") No insights are shared, there is nothing in the way the material is summarized which says Dr Sze paid attention to making a unified presentation. Some sections are horrible, while some sections are reasonably readable. It's no excuse to say that this is not a text book but a reference work.
