The Foundation Directory is a powerful tool for identifying grantmakers and learning more about what they have funded in the past. You can use this information to help identify a grant you might apply for and to improve your own application.
Pivot lets you search through current funding opportunities. To use Pivot, you'll need to create an account while in the Ohio University IP address range (basically, on campus).
The Foundation Center offers the Grant Space website as a place to find training tools and resources to help you learn how to write an effective grant application.
This Foundation Center service provides access to papers and case studies addressing social issues. Each document indicates which grantmaking organization funded the work.
