Bests & Worsts Reviews from Amazon

First of all, great book. Been writing professionally for 20 years, and I still use this book occasionally. WARNING on REVIEWS: Amazon is using the same customer reviews for "The Elements of Style, Fourth Edition" by Strunk and White (1999) and "The Elements of Style - the Original Edition" by Strunk (without White) (1920), re-published September 2007. Since the republication of Strunk's original work was released in September 2007, all reviews before that date pertain to "Strunk & White." Any review after that date, unless clearly indicated, could pertain to either book. The books are markedly different, but Amazon is using the same customer reviews for both.
