The Center hosts several regular seminars during the academic year, supports a working paper series, and maintains a reference library. It hosts special events beyond Harvard, such as the "emerging issues" series of conferences on legal and policy issues in the nonprofit sector, co-sponsored by the Urban Institute. It also brings leaders of nonprofit institutions to Harvard, such as its senior research fellows William F. Baker, Peter Bell, and Steve Lawry, as well as the participants in its 2008-09 series of talks by new leaders in philanthropy. Christopher Stone became Faculty Director in 2008, the same year in which Aviva Luz Argote became Executive Director. Other notable faculty members include Mark Moore, L. David Brown, Marion Fremont-Smith, Marshall Ganz, Christopher Winship, Archon Fung, Herman "Dutch" Leonard, Christine Letts, and Bryan Hehir.
