The Financial/Business Models workstream will make recommendations for a sustainable business plan for the DPLA. Any effort to greatly increase the scope of public access to digital resources will require partnerships among many entities, public and private, including government institutions, foundations, libraries (public, academic, and special-purpose), and publishers, both for-profit and non-profit. The combination of business models and mechanisms required to support a successful effort is likely to be complicated and varied, reflecting substantial differences in the primary missions of the participating institutions. How much the effort costs will depend on both technical and organizational needs; this workstream will consider these aspects simultaneously to ensure that there is a sustainable model for the DPLA. Philanthropy will be a good starting point, but the effort must have a business model and a means of drawing on core funding from libraries and governments in order to get to scale. New models for working with publishers will be a component of this project.
