Title: Older Version Better
Review: Bought this as a replacement for one purchased over 20 years ago, when you had to "know someone". First 5 minutes flipping through the book, right away stopped 3 errors that weren't in my old version. Disappointing. Make sure you have a good teacher to help you correct these.
