El libro como sistema: hacia un nuevo concepto de libro

The times we live in are not exactly times of certainties. Nothing we now know, even the latest scientific discovery, is guaranteed a space in a hyperconnected and fast-changing planet. In this context, we are witnessing a shift from analog to digital. In this paper we discuss the development of a new concept of book which, with its digital transformation, is operating beyond the object to be a transmedia communication system through three processes: disruptive technologies, disintermediation, and socialization of the book and the act of reading. Keywords: ebooks, social reading, digital reading, hypermedia, transmedia, multimedia, disintermediation, disruptive technologies
