Class-tested by over 2,000,000 students at over 1,500 schools, A Writer's Reference is the most widely adopted of all hand-books. This is a book that students can -- and will -- use on their own. The new fifth edition expands coverage on research and argument and is now thoroughly integrated with an enhanced companion Web site developed by Diana Hacker herself. On the Web and in print, Diana Hacker remains the source students and their instructors can trust.
