This guide presents Library resources for identifying potential grant funders. It assumes you are steeped in the language and literature of the research/creative activity/project you wish to apply for funding to accomplish (if not, see Research Guides, by subject to find more literature on your topic).
The world of funders - federal agencies, foundations, non-profits - has its own language and jargon. Somehow, you need to connect those two separate languages and cultures.
An important first thing to consider is: how much money are you seeking?
If your project is relatively small (in the $5,000-or-less range), then the appropriate sources of funding are most likely private or local foundations. To find these funders, use the Foundation Directory.
If you will be searching for funding from federal (or state) agencies use CFDA or go directly to the agency website.
To search a broad range of private and government funders, use SPIN.
