College and University Rankings, compiled by Nancy P. O'Brien, Head of the Education and Social Science Library at the University of Illinois at Urbana-Champaign, provides an annotated list of resources that rank higher education institutions. The list of ranking resources is conveniently divided into five sections: general/undergraduate, graduate, business, law, and international. However, this site is not merely a list of sites; it also includes an informative essay entitled Caution and Controversy, which questions and evaluates the methods and usefulness of ranking services, and provides users with electronic and print resources for the independent assessment of ranking services.
