The Thirteenth Edition of the Harbrace is the result of an exhaustive market research effort to make a great handbook even better. Over 300 faculty members participated in reviews， surveys， focus groups， and telephone interviews. The result is the first significant revision to the Harbrace in its history. While remaining a grammar-first handbook， the Thirteenth Edition reflects a complete reorganization of chapters， new examples from contemporary writers， and a writing style that is more descriptive than prescriptive. The new Harbrace is easier to use and more accessible to students than ever.
