There are many sources to find federal, foundation, and corporate funding.  The following list should not be considered exclusive, but rather a starting point.

Federal Funding

The definitive source of Federal grant information is the Catalog of Federal Domestic Assistance.  This is a comprehensive catalog of all financial support available from the federal government, including research grants, scholarships, state grants, non-profit grants, and private assistance.

The Federal Register provides a uniform system for making public regulations and legal notices issued by Federal agencies available to the public.  This includes some grant availability.

The Official Federal Government Websites of the Executive Branch provides links to the federal departments and independent agencies.  Review the department and agency websites to find information about programs under each jurisdiction.

National Science Foundation funds research and education in science and engineering through grants, contracts, and cooperative agreements.

Society of Research Administrators GrantsWeb is a collection of hundreds of links to funding resources from federal and state governments.  It includes links to federal agency policies, electronic journals, grants forms, and writing guides.

TRAM is a website developed by the Texas Research Administration Group which locates funding opportunities from many different agencies.  The funding information is updated daily.

Foundation Funding and Corporate Funding

The Foundation Directory is maintained by the Foundation Center, an independent, non-profit information clearinghouse.  The Council on Foundations is another source for funding.  PhilanthropySearch.com is a search engine serving the nonprofit and philanthropic sectors.
