Every day, regulars, students and ordinary visitors come to the Bibliothèque Publique d'Information in the heart of Paris. Wandering through the crowd, in the stacks and in the margins of the library, we meet inspired students, enlightened amateurs, hardened loners, idle regulars, feverish artists - By appropriating one or other of the thousands of cultural resources at their disposal, each one "inhabits" the library in their own way. And each one shares with us his or her way of being inhabited by a text, a music or a video.
