Having helped nearly 3 million students at 1600 colleges and universities to write well, A Writer�s Reference succeeds because it has always been grounded in classroom experience. Nearly twenty years ago, Diana Hacker reinvented the college handbook by looking at her own students� needs. She crafted a first-of-its-kind reference that offered practical solutions to college writing problems in a language students could understand and in a format that was easy for them to use. Her many innovations � hand-edited sentences, grammar checker boxes, student-friendly index entries, ESL coverage, and a lay-flat comb binding � have been widely imitated but never improved upon.
