Thanks to the readers who wrote to report mistakes and typos! I incorporate reader feedback in periodic revisions. Please contact me at rhammack@vcu.edu if you find any additional mistakes, no matter how minor.

Notice: On July 24, 2020 I issued edition 3.2 in print and PDF (ISBN's unchanged). This slight revision corrects a handful of typos found by readers. Also, after living with the red cover for two years, I switched to a more contemplative blue. All orders printed after July 24 will have the blue cover. (Amazon may still show the red cover.)

Note to adopters: Your bookstore will need to know that the book is distributed by Ingram. Please let me know if you use Book of Proof in your classes and I will update the adoptions list. Thanks!
