Le Web 2.0 dans les bibliothèques : vers un nouveau modèle de service.

This article uses the concept of Web 2.0 to define the concept of "library 2.0". It suggests that the recent analyses of the evolution of the service offer of libraries are necessarily linked to the knowledge of technologies and to the philosophy underlying the Web 2.0. The purpose of such an undertaking is to examine new ways of operating libraries that coincide with the research and the information-seeking habits of users. Technologies such as blogs, Wiki sites, RSS feeds and social networking play an important role in the evolution of the service offer. This article examines a new concept of library operations in which notions of co-creation and evolutionary and interdependent service are key; they constitute the framework of an "ecosystem" library. With co-creation in mind, the authors study the role of the user in this "ecosystem" as well as the changes to be undertaken from the point of view of the users, the organisation and its mission.
