A proven success, A Canadian Writer’s Reference, Fourth Edition, remains the easiest reference tool to use and understand. Updated with Canadian content and conventions, the fourth edition features new contributing authors who bring a wider range of teaching practice to the book — and who have shaped a writer’s handbook that serves an even broader and more diverse student body.

Students write every day and everywhere — for school, for work, and for fun. And nobody else in the field of composition understands the real world of student writing better than Andrea A. Lunsford. Her trademark attention to rhetorical choice, language and style, and critical thinking and argument — based on years of experience as a researcher and classroom teacher — make The Everyday Writer the tabbed handbook that can talk students through every writing situation. But wait — there’s more! New research into student writing now informs every page of the new edition…and with expanded, more visual coverage of the writing process, research and documentation, and writing in the disciplines, today’s Everyday Writer prepares students more than ever for everyday writing challenges — from managing a research project to writing on a Facebook wall.
