Work on the History of Cartography Project has been accomplished with funding from both public and private sources, with grants and donations, and with resources and research release time provided by academic institutions.
The National Endowment for the Humanities and the National Science Foundation provide major grants to the History of Cartography Project, and the series simply would not exist without the great confidence in our efforts that both federal granting agencies have demonstrated.*

This funding and the long-term viability of the History of Cartography Project depend on additional support from individuals, private foundations, and corporations. Private donations are especially important as they release federal matching funds, as available. Broad support demonstrates that The History of Cartography is a valuable resource, and that completion of the series is eagerly anticipated.
