Rules for Writers succeeds because it has always been grounded in classroom experience. By looking at her own students' needs, Diana Hacker created an affordable and practical classroom tool that doubles as a quick reference. Developed with the help of instructors from two- and four-year schools, the sixth edition gives students quick access to the information they need to solve writing problems in any college course. In the Hacker tradition, the new contributing authors -- Nancy Sommers, Tom Jehn, Jane Rosenzweig, and Marcy Carbajal Van Horn -- have crafted solutions for the writing problems of today's college students. Together they give us a new edition that provides more help with academic writing and research and one that works better for a wider range of multilingual students. Flexible content options -- in print and online -- allow students to get more than they pay for.
