We expect foundations to have money but not to advertise its availability. Those who seek foundation funding look for a suitable match; that is, foundations with matching interests and sufficient funds. For this information:
The Foundation Center has been doing this for a long time. Staff collect information about foundations (many are reported not to have websites) and create a searchable database of foundation information. Plus, the organization supplies educational materials on topics related to philanthropy. For access:
Guidestarproclaims itself to be "the world's largest source of information on nonprofit organizations," including foundations. There's a free search option and a "premium" option, which requires payment.
NOZAdescribes itself as "theworld’s largest searchable database of charitable donations," including foundation grants. For those signing up outside the UT umbrella, there is a small-group free option for searching the foundation information.
