Based on the latest Sisk data, here are the ten most-cited active law professors in the U.S. for the period 2016-2020 (inclusive) (remember that the data was collected in late May/early June of 2024, and that the pre-2024 database did expand a bit since then).  Numbers are rounded to the nearest ten.  (Law professors not teaching in 2024-25--e.g.,those who are now retired, in government service, etc.--are not included [faculty merely on sabbatical are counted].)
