As we build the digital library, we need to be careful not to carelessly obliterate some of the important features of current libraries. Many proposals for digital libraries remove social exchange and interaction, focusing narrowly on the technical mechanisms of information access. This is not only unwise, it is unnecessary since we could provide mechanisms for social exchange and interaction within our systems. Simply put, we do not need to remove the social world from our systems. This paper discusses why such interaction is important, and then presents a toolkit, called the Cafe ConstructionKit, that can provide computer-mediated communication support at low cost.
