Style: The Basics of Clarity and Grace, 4th Edition by Joseph Williams

This book summarizes Joseph Williams's theories of writing well in ten chapters. The book is a condensed version of the longer Style: Lessons in Clarity and Grace, and I think the condensation may make the book harder to understand and use for someone not already familiar with Little Red Schoolhouse principles. I think the principles themselves are sound--especially for those who want to write persuasively (as opposed to fiction or creative non-fiction). This book would be a good supplement to a course, as long as the instructor is committed to reinforcing the book's principles in class.
