Muriel Harris was the director of the Purdue Writing Center where she worked elbow-to-elbow with students for over twenty-five years. Based on her experience assisting thousands of writing students, she authored the Prentice Hall Reference Guide with several goals in mind. The handbook is brief, with the most concise explanations possible. It is tabbed for ease of use, enabling students to quickly find what they’re looking for. And, it features the foundational teaching tools she developed during her tenure at the writing center: the innovative Question and Correct and Compare and Correct features. These features address the challenges that student writers face in an accessible, easy-to-use manner. The streamlined and user-friendly organization and innovative student-focused features make the Prentice Hall Reference Guide the easiest handbook for students–and instructors–to use.
