This monograph examines how partnerships were used to enlarge cultural participation by organizations in the Community Partnerships for Cultural Participation (CPCP) initiative. It discusses different types of partnerships (such as those between large and small organizations and cross-ethnic partnerships) and different uses of partnership (such as expanding artistic programming and engaging new audiences). The monograph concludes that partnership can be a powerful tool for strengthening participation, but its possibilities and limitations must be better recognized so that it can be used more effectively.
