A college professor copies seven (7) chapters from a book called "How to Get Better Grades – A Creative Approach". There are ten chapters in the book. She incorporates this material into a packet of materials that were printed in her college’s copy center. The packet is then placed in the local college bookstore and is placed in the required materials list for 150 students to purchase. The author of the book (from which the professor copied seven (7) chapters) believes that the professor has violated his copyright. Which is the most true?
