The e-book prompts us to reconsider the printed book as a “circulating” device. Consideration of printed book circulation, whether it occurs through material exchange, through conversation or through written forms such as annotation, helps us to understand the effects of the digital revolution. Our ongoing research on digital reading has pointed up the differences between e-books and music; we have also identified the factors which tend to reduce the appeal of the e-reading experience. For both e-books and printed books, reading indeed implies exchange, conversation, and writing. Our study, however, through interviews, a questionnaire and a topology of web sites related to books, highlights significant differences between the two.
