How does one review a textbook? It was readable and informative. Since this was for an online course, I knew I was going to have to read the whole thing and since that would take away from my pleasure reading, I decided to count it. Didn't quite get it finished before the semester ended because of writing papers -- just skipped around in the last few chapters. I am glad to have gone back and read the parts I skipped while on summer break. I learned a few things in the final reading.
