Online Resources

General Information on Grant Writing and Research
GrantStation
GrantStation has ommitted foundations that do not accept unsolicited proposals and others that offer only scholarships. This results in fewer foundations than in some other databases, but more complete information is given here for most of the foundations that actually might help you. Information on corporate and government grants is also included. This is a pay service, except for a free weekly newsletter. Readers of the second edition of my book receive a free trial membership and a discount on full membership.
