Harvard University regained sole possession of the top spot in the new U.S.News & World Report's Best Colleges 2011 rankings.

Last year, Harvard and Princeton University tied for first, but Princeton fell to second in the 2011 rankings of these large, research-oriented institutions.

Williams College can once again boast that it's the nation's top-ranked national liberal arts college -- a category of schools that place a higher emphasis on undergraduate education -- as it ranked a spot ahead of fellow Massachusetts liberal arts school Amherst College for the second consecutive year.
