Not a library... a center: "The mission of the William J. Clinton Presidential Foundation is to strengthen the capacity of people in the United States and throughout the world to meet the challenges of global interdependence. To accomplish this mission, the Foundation currently focuses its work in five critical areas:

Battle against HIV/AIDS
Racial, ethnic and religious reconciliation
Citizen service
Economic empowerment of poor people
Leadership Development

The Foundation works principally through partnerships with like-minded individuals, organizations, corporations, and governments, often serving as an incubator for new policies and programs. Former President Clinton established the Foundation and advances its mission by using his vast public and private networks to initiate research, dialogue and action."
