Foundation Directory Online (USA)
The Foundation Center’s Foundation Directory Online allows you to search their databases of more than 100,000 American foundation grantmakers and more than 2.4 million grants. This subscription service starts from $19.95 (about £12) a month and it is a really useful resource for finding US foundations. For ‘Professional’ subscribers, you also get free access to the Map of Cross-Border Giving as part of your subscription. For certain subscriptions it also allows you to search their company giving database, as well as search IRS 990 Forms (annual accounts) of grantmakers.
