16．"The price of books for our students is just getting higher and higher and，com-bined with the rising cost of tuition，it'S killing these students，"said Peter Jason，a col-lege professor．"Remember，students are one of the poorest groups of people in Ameri-ca．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 lire 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．"
