Pittsburgh. During the 1950s and 1960s, the School of Law's Health Law Center was an early pioneer in the field now known as computer-assisted legal research (CALR). Attorney and researcher John Horty was astounded by the extent to which the laws governing hospital administration varied from one state to the next across the United States, and began building a computer database to help him keep track of it all. News of Horty's pioneering work at Pitt inspired the Ohio State Bar Association (just across the state line in nearby Ohio) to create its own separate CALR system, the ancestor of the database system known today as LexisNexis. The School of Law moved into their own dedicated facility, the Barco Law Building, upon its opening on the university's main campus in 1976. In 2007, one ranking put Pitt's Law School faculty as 21st in the nation based on scholarly impact. Pitt Law is currently ranked tied for 78th out of 199 in U.S. News & World Reports rankings of America's top law schools and in 2009 was listed among the "Best Law Schools" by The Princeton Review. Pitt Law is also one of 80 law schools with membership in the Order of the Coif.
