The training handed out by the Ecole des Chartes is oriented towards research and privileges an historical approach. Within a larger framework around the question of text transmission, books and pictures, library history has a long and rich tradition. Since 1995, a dozen theses have been devoted to institutions or to collectors. The Ecole des Chartes organizes, with the aim of favouring an interdisciplinary exchange, international study days which form the subject of publications. Finally its web site offers a variety of resources on library history.
