HyperOtlet is a multi and transdisciplinary project about a major book in the history of information sciences: Le Traité de documentation, written in 1934 by a Belgian lawyer: Paul Otlet († 1944). Passionate militant of a new field, documentation, he created original tools and practices and thus, a new knowledge tradition. HyperOtlet will articulate a set of historical and documented research with a collaborative digital device and elaborate an augmented corpus around 4 axes: new contextualisations of digital culture (documentary regime, Muller); discussions about current issues of documentation in digital humanities (Le Deuff) of documentarity (Pédauque) and documentality (Ferraris); promote the creation of an epistemic community able to represent an European documentary tradition; develops new ways in consulting, reading, navigating in written works (ENSSIB, MSHPN).
