Students at Northwest Missouri State University have started spring term classes，but many aren’t carrying thick textbooks．Instead，most students are carrying a lightweight electronic tool that can fit into a coat pocket which holds the textbook material for all their classes．Some students will also download their text information onto their laptops．（筆記本電腦）．

At the university，textbooks are fast becoming a thing of the past．Besides taking a load off students’ backs，going textbook-free can save them a lot of money．The pilot electronic textbook program began in autumn with four classes and about 200 students．This spring about 4，000 of the school’s 6500 students will use electronic textbooks．

Textbooks publishers say many colleges are moving toward using some electronic textbooks，but Northwest's plan to eventually eliminate all printed textbooks makes it a leader in the movement．

“Right now，digital products account for（占）a small percent of our higher education business, but it is growing at a rate that is breathtaking（激動(dòng)人心的），”said Jeffrey He，a product manager for McGraw—Hill Education

“But Northwest can only move toward a bookless campus as fast as the availability of e-books allows，”said Dean L．Hubbard, Northwest’s president．“Publishers don’t have all textbooks online yet．But I would think as a realistic guess we could be totally out of the printed textbooks business in three years”

The idea pleases Mike Jenkins，who is in the second year at the university．“ I think the whole idea is pretty cool，”said Jenkins．He used e-books in his history class during the autumn term“I would like it if we didn’t have textbooks at all anymore，”he said“You wouldn’t have the trouble of messing with hooks．The e-book is so convenient，and you don't have to carry all those books around．”

Also，unlike printed textbooks，e-books have interactive（交互式的）quizzes and the ability to search the full text within seconds for key words．
