Now that university libraries have put training in place for students, they have several objectives: material expertise, help in the transfer from college to university, fighting against failure, an intellectual apprenticeship, and all this through active, personalized methods. In reality, the programmes offered must compromise over the few hours allocated and with instructors of differing status. Certain objectives remain accessible (a minimum of material competence or location of a space better adapted to the university); others are much more difficult to realize. To acquire method also implies managing time, use of reason, the capacity to handle language, the choice of the means of observation, empirical or ethical rules. And information research is no more than a very small part of the research process.
