North Carolina State University gives students free access to physics textbook online

"Physics students at North Carolina State University can get their introductory-level textbooks for free thanks to a new program by the college. Each year about 1,300 students at North Carolina State take Physics 211 and Physics 212. Beginning this semester, the university's libraries and physics department have offered the courses' textbook online for free. Students can also print pages of the text or buy a printed copy at the university's bookstore for about $45. Michael A. Paesler, head of the physics department at North Carolina State, said his department wanted to find a cost-effective way for students to get course material and felt an online option might work well. The department hopes to offer more material online, including an optics text written by Mr. Paesler to be used for a course next semester"
