Query: This book is the First Aid Manual for Every Serious Writer.

As an English instructor, I have mulled over various texts in the search for the most student and instructor accessible book. My search ended when I found Professor Hacker's A Writer's Reference. This concise work includes introduction to grammar and style, a review of the basics, and an extensive guide to research.My colleagues and I agree that Professor Hacker's book should be required as a resource in English courses. The book is true to its title; it is a writer's reference.
