With its Web platform dedicated to Literature Essentials in Gallica, the French national Library (BnF) seeks to enhance its heritage collections by offering a digital cultural mediation intended to the educational community. Which theoretical choices and editorial biases governed this website development? How can the Essentials of the BnF, by seeking to model practices, support the reflection currently being carried out in literature didactics on the renewal of teaching and learning methods? To answer these questions, we will adopt the methodological approach of the information and communication sciences by seeking to articulate discourse, device and use. We will place the project at the heart of a dual issue of a revival of literary history and educational practices themselves revisited by digital technology.
