What makes the global spread of community philanthropy organizations so exciting is the variety of forms they take, adaptations to different local contexts, challenges, resources, and leaders. The core similarities matter -- all in some way help geographic communities mobilize financial and other kinds of capital for improvement of the lives of residents. But so do the differences. Some have endowments, some don't. Some are large, more are small. Some call themselves community foundations, others do not. This diversity is one sign of community philanthropy's flexibility, potential, and rising popularity. But it also presents a challenge to those who want to better understand and support community philanthropy, especially on a global level. A practice so varied, so organic and tied to local conditions, complicates classification, resists general conclusions, and calls for lots of learning through example. A movement relatively young and quickly evolving, with a limited body of applied research, requires ongoing documentation and study. The case studies presented here provide intriguing snapshots of locally driven development in communities across the globe.
