Jon Harrison of Michigan State University Libraries maintains this database of Grants for Individuals, mostly scholarships and financial aid. It stays pretty current, and John Harrison does a great job.
You can search by Academic Level (for example, Precollege Funding or Graduate Funding); by Population Group (for example, Disabled, Minorities, or Veteran); or by Subject (for example, Animal Science & Veterinary Medicine, Communications, and Writing).
