Presentation of the principles underlying the reform of the ENSB (Ecole nationale supérieure de bibliothécaires). Its aim is the federation of the information professions, with various education paths, from information retrieval to cultural events and conservation, which will be specialised options after a common-core syllabus. Just as varied, information science rests on interdisciplinarity. The new school will have to diversify its recruiting, to be a training center for all the partners of scientific, technical and cultural information : the programme will have to include production and diffusion. Actually, the ENSB has already made an agreement with two universities so as to set up two DESS grades : " Informatique documentaire " and " Politiques culturelles " ; continuing education operations have also been launched.
