    "The price of books for our students is just getting higher and higher and. combined with the rising cost of tuition. it's killing these students. "said Peter Jason. a college professor. "Remember. students are one of the poorest groups of people in America. Almost half of them have at least one part-time job. In fact. one of my students has three jobs. And she still manages to have high scores and go to school full-time. "

    Textbook prices are traditionally high. Adding to that problem, many college teachers change textbooks year after year; they either upgrade to a new edition or switch to an entirely different textbook. This further hurts students because if an instructor no longer uses a particular textbook. that book has no resale value.

    Dr. Jason decided to make reading a little easier and a lot cheaper for his students by writing his own book on public speaking. "Many books have an increased price because of CD-ROMs. lots of color photographs and pictures. I talked to my students. and many of them. like me. prefer to keep things simple! So. a few years ago. I wrote my own textbook. Compared to most other public speaking books. mine is half the number of pages. and one-third the price. That is. $30 instead of $90. When I wrote a second edition last year. students only had to buy the 35 new pages, For only $7. 00. they had almost a new book. Now my loose-leaf textbook enjoys great popularity among the students. Maybe in the future more writers and publishers will try it."
