This book had many obtuse examples that did not support the points being made. It wandered all over the place with no real organized format. There was no stepping stone approach. Frequently the examples were gramatically incorrect. The professor spent more time in clas explaining what Radford meant than teaching new material. I can honestly say that in all the text books I have ourchased for my 130 hours of college credit this was the worst to work from. There were major gramatical errors every 1-2 pages. Many topic were explained with no further reasoning than "Becase I said so." The author assumed that the reader was going to continue on for a doctorate and not e sitting in a sophmore class struggling to come to terms with his difficult jargon. The professor I had for this course ultimately decided to drop the book after one semester,
