Query: Get the 3rd Edition

The second edition of this classic work improved on the first edition, and the third was the best of all. It was perfection. The fourth, posthumous edition slips a little bit. It's still better than any other style guide, but a hint of Political Correctness has crept into some of its advice and examples. Why did the publishers feel the need to tinker with perfection? If you already have the third edition, don't bother getting the new one. If you don't have any copies of this great book, check the used bookstores for the previous edition.
