For introductory and advanced composition courses. When Muriel Harris was first asked about the textbooks she used for tutoring in her Purdue University writing center, she said she didn't use any. At that time she hadn't found any text that could effectively help her students. When asked whatwouldmake a textbook effective, the answer came easily: 30 years of tutoring experience had taught her that a truly useful textbook would have ways to help students find the information they were looking for without having to know the terminology, would be clear and easy to understand for all students, and would be written in a student-friendly language and tone to avoid the intimidating formal instructional tone of some handbooks. Before long, these principles became the foundation of Harris'sPrentice Hall Reference Guide,now its 7th edition. With new material and emphasis on writing research papers, visual argument, multimedia, document design, and a visual guide to documentation,PHRG7e continues to help students find the information they need. With easy to find information, clarity of instruction, and a student-friendly language and tone,PHRG7e continues to help students effectively use and understand their handbook.
