The evolution of the Web 2.0 offers new opportunities for science, in particular new forms of participation, interaction and communication. The various facets of this evolution are addressed under the key phrase “Science 2.0” in the Leibniz Research Alliance of the same name. In the course of Science 2.0, libraries have evolved into modern information infrastructure institutions (hereinafter named Library 2.0) which offer new added values to users resp. researchers, and which have been feasible only thanks to Web 2.0. As of this moment, both the general opportunities of the Web 2.0 and the added values presented by a Library 2.0 are mainly technology-driven, e.g. they exploit the new technical capabilities. There has been little discussion so far whether these new services and added values are useful to, or even desired by, the users or the science community. At the same time, initial empirical studies on the acceptance of Web 2.0 services in the German science landscape show that only a minority have integrated the new capabilities of Science 2.0 into their scholarly work routines.
The preliminary work of this project addresses the added values of a user-centered Library 2.0. It focuses on Library 2.0 because modern information centres play a crucial part in the dissemination, information and provision of Web 2.0 services for scholarly work.
