This contribution is aimed at analyzing the links between books and hypermedia in a selection of literary apps for children. Considered under the prism of remediation and media hybridization, these relationships can be gathered into four typologies: the adaptation of the printed text into a hypermedia app (where the book comes before app); the opposite direction, leading from a hypermedia app to a print book (where the book comes after the app); the co-construction, implying the combined use of a printed book and an app for accessing a single work (where the books comes alongside the app); the internal figuration, integrating representations of books and readers in the diegesis (where the book is inside the app). Through this, two hypotheses are questioned: the link between the book’s hybridization and the dual destination of any children’s product; the shaping of a stereotyped and reassuring imaginary, finalized at introducing the young reader to the symbolic universe of the book via the digital media.
