The Thirteenth Edition of Hodges' Harbrace Handbook is the product of an extensive market research effort, involving over 300 faculty members from around the country at both two- and four-year colleges. The resulting product information formed the basis of our revision for the Thirteenth Edition. While retaining the familiar chapter organization that the Harbrace has always had for sections one through five -- Grammar, Mechanics, Punctuation, Spelling and Diction, and Effective Sentences -- the Thirteenth Edition contains more chapters and expanded coverage in the Larger Elements section. Hodges' Harbrace, like our two other versions of the Harbrace, retains our commitment to quality, our commitment to being the most authoritative handbook on the market.
