Printed textbooks and copied handouts had been the traditional materials used in the classroom. Not anymore.

The 21st century has brought about a paradigm shift from cumbersome printed textbooks to a paperless, green, electronic era. e-Books are becoming more and more popular with not just recreational readers, but also academic readers.

e-Books are popular not only because they are much cheaper than their printed counterparts, but they also take up less space in your bag, and require less natural resources to manufacture. One e-reader takes up much less space than the the bookshelf filled with the equivalent number of books.

Why not try an USB flash course drive and see for yourself the benefits of price and portability.
