Libraries evolved to meet needs in a time of when information materials were distributed and consumed in physical form. Their services and their cooperative arrangements reflect this. Our discussion about digital has tended to focus on tools and collections, but what happens to the structure and organization of the library, its role within the university and the cooperative arrangements it makes, as the network reconfigures how research and learning are carried out? This presentation will present a framework for thinking about the research library as its services, expertise and boundaries change in a network environment.
