The major influence on library futures is the changing character of their user communities. As patterns of research, learning and personal development change in a network environment so library services need to change. At the same time, libraries are focused on engaging with their communities more strongly - getting into their work and learning flows. This means that libraries are becoming more unlike each other, they are diverging as they meet the specific needs of their communities. Research libraries diverge from academic libraries, and each is different from urban public libraries, and so on. At the same time, at a broader level libraries are experiencing similar pressures. The need to engage more strongly with their communities. The need to assess what they do. The need to configure space around experiences rather than around collections. Libraries are converging around some of these issues. This presentation will consider the future of libraries from the point of view of convergence and divergence between types of libraries.
