Abstract : The new informational context leads to pose the information retrieval training's question with the emergence of new practices, new representations of information and knowledge and mostly the acuity of unobserved socio-political stakes. This training is currently shared between library instruction and digital literacy. First it should be necessary to decrypt the major facts of this informational context that must fuel the training's debate. We study in this way the manners, the speeches and stakes of information. After a quick reminder of currently training's feature in research tools at the universities, the various dimensions of teaching culture of information to students must be studied. Finally we show the difficulties and epistemic matters that researches about didactic of the information at the university must be able to face.
