You’ll want to make the Foundation Center your first stop offline as well as online when researching foundation and corporate funders. It started out publishing its funder directories in printed form, and it’s continued to do so, although more and more it directs you to its online resources.
The Foundation Center operates offices in New York; San Francisco; Atlanta; Cleveland; and Washington, D.C. (Find the addresses in Appendix B.) Nearly 400 reference sections at public and private libraries and community foundations make Foundation Center publications and other reference works available for free. You can find these addresses in the front of directories published by the Foundation Center and on its website.
