The Project on Student Debt has a list of 52 colleges that limit or eliminate student loans for the neediest of students. In some cases, loans are limited or eliminated for students from middle and upper income families as well. You can always go and navigate to these guys when you want to get instant loans for college.
Williams College and Dartmouth College were recently in the news because they have decided to back off from their no loan commitments. Both colleges are still on the list of 52 colleges because they have reduced loans although not totally eliminated them.
