It's difficult, I think, to keep track of the funding sources one might use for education. Student loans or in-house financial aid are pretty straight-up; but there's lots of other grants and other financial opportunities (like the one I posted below) that are not easy to stay on top of.
When it comes to graduate education, at least, many schools have sought to organize this material for their students. My graduate alma mater, Indiana, has a very good site where they organize graduate fellowships by discipline and other qualifications or pursuits. Their newsletter is regularly updated and archived. If you are in, or thinking about, graduate school, take a look here.
