Looking for CSV importable list of American Universities and Colleges

I'm looking for a CSV list of all US universities and college campuses.

I'm also debating whether to create a custom content type "college" to allow users to add their university/college campus or instead finding a free CSV list which I can import and just prepopulate the content type. Another possible option is using geolocation to "suggest" a campus.

I need to be able to specify during import fields such as "campus name," "city," "state," and "zipcode." "street address" would be ideal.

Is anyone aware of any such freely available list? If one does exist, what's the best way for doing an import?

Thanks
