The Foundation Center

The Foundation Center has long been a leader in providing resources to the philanthropic community. Their site includes a search form that returns basic information about private foundation funders, as well as links to their 990s. They offer a number of other fee-based services for foundation researchers.


Guidestar is another source where you can search for basic information about nonprofits (i.e. public charities) and private foundations and obtain their 990s.
