Style: Ten Lessons in Clarity and Grace (7th Edition)
By Joseph M. Williams
A short review. I still have the third edition of this book, which I used in a technical editing class (I think) in my MA program. It had a big impact on my writing style. The seventh edition is similarly illuminating, and it's also genuinely pleasurable to read.
On the other hand, Williams' own style is a bit talky for me. I lean toward much more spare prose, and I take a harder line against expletives. That hard line probably stems from my tech comm training and orientation.
In any case, a great book. I'm about to take a look at the short version, Style: The Basics of Clarity and Grace (3rd Edition).
