Sustainability for digital libraries

Economic sustainability is a pressing concern for many digital library projects. One key to achieving economic sustainability is to make the digital library an integral part of its parent organisation. This can be done by having a sound product, launched at the right stage, and valued by users. Influential champions for the digital library are also required and librarians must be prepared to network and cultivate useful contacts. Funding sources can include sponsorship, in‐kind support, fee charging and the ultimate aim, integration.
