The purpose of this study is to identify reading effect of e-book versus printed book. For this purpose, 8 elementary school students participated in the reading project. The participants of this project read 'A'(printed book) and 'B'(e-book) literary works and were tested reading comprehension. According to conclusion of the study, there is no difference between printed book and e-book on reading effect. It is expected that this result can be used for e-library management and reading education.
