Strunk and White's The Elements of Style

William Strunk was The Elements of Style's original author and E.B. White revised it later, making some changes and adding the section on style. Four of the book's five sections list rules and discuss them, including incorrect and correct examples. "Elementary Rules of Usage" covers basic grammar and punctuation rules. "Elementary Principles of Composition" discusses how to organize information. "A Few Matters of Form" focuses on the mechanics of page makeup and punctuation. "Words and Expressions Commonly Misused" contains what the title says, though the information is dated--some are not as common today, and some misused words and expressions commonly misused today are not listed. "An Approach to Style" features instructions, ruminations, and encouragement on developing a particular style, with warnings to keep the style appropriate to the subject matter. The book's quick reference format, readable style, conversational tone, helpful information, and examples of incorrect and correct examples make it useful for beginning writers and veterans who need a reminder.

P.S. E.B. White . . . yes, it's that E.B. White, the author of Charlotte's Web, Stuart Little, and
The Trumpet of the Swan :)
