This Social Innovation Resource Guide is a work-in-progress that attempts to capture various resources that assist, advise, and document social innovation. Social innovation -- defined as "a novel solution to a social problem that is more effective, efficient, sustainable, or just than existing solutions and for which the value created accrues primarily to society as a whole rather than private individuals" -- is drawing widespread academic interest. This Resource Guide began as an instrument for law students enrolled in the Social Enterprise & Nonprofit Law Clinic at Georgetown University Law Center. In it you will find find foundations that support social innovation, organizations that are creating metrics to measure social innovation, attorneys who counsel social innovators, centers and incubators that grow social enterprises, and much more. This Resource Guide is meant to be collaborative and dynamic, and useful to all.
