The purpose of this study is to investigate students' usage and acceptance of electronic books. Factors correlating with students' attitude towards e-books were examined using the Technology Acceptance Model (Davis, Bagozzi, & Warshaw 1989). A questionnaire was administered online for students at University of Hagen. Results indicate that nearly two thirds of the participants had read electronic books. E-book users emphasized 24/7 access and access from home as significantly important attributes whilst non-users reported the preference for print books as the main reason for not reading electronic books. Applying the Technology Acceptance Model, perceived usefulness and perceived ease of use were both correlated to students' attitude towards e-books. Moreover, we found a negative relationship between the emotional attachment to paper books and the attitude towards e-books whilst prior knowledge and technology readiness correlated positively with the attitude.
