Highest Impact Law Journal: Harvard Finally Beats Yale

According to Thomson Scientific Journal Citation Reports, the Harvard Law Review has overtaken the Yale Law Journal as the law journal with the highest "impact factor", a common measure of publication influence in the field known as bibliometrics.

Impact factor is measured using "the number of all current citations to source items published in a journal over the previous two years and dividing by the number of articles published in the journal during the same period—in other words, a ratio between citations and recent citable items published".
