With the spectacular development of digital libraries since the 2000s, the modes of indexation of these archives have also gotten diversified. Considering the thought of library organization across ages, one observes that history has for a long time been dominated by the attempt of a unique documentary classification, correlated to a world outlook inherited from Aristotelian philosophy. In this paper, I try to bring to light this multi-secular relationship between a vision of the world or of the human mind, and the way indexation of archives is supposed to reflect it into space. World order and books order are echoing each other, destined for a bursting and re-composition at the digital era.
