Social science libraries now have an important role to play in the context of the information society as significant sources of academic and social knowledge. This work provides information on the development and use of digital resources in the social sciences emphasizing best practices; an articulation of some of the problems presented to providing these resources; and a view to the use of these resources to support sustainable development.
