Abstract : The aim of our article is to show the evolution of libraries inside web 2.0 environments and to explain how culture of information can be a new way for information literacy. Library 2.0 is not a reality yet but some librarians try to use new tools to add digital services. Information literacy must evolve too. We wish in this article to expose some results from a doctoral thesis. Culture of information is both a possible translation and a more ambitious vision of information literacy.
