Professor Ted Sichelman (University of San Diego School of Law) has published an interesting list of the most cited tort related law review articles published within the last 25 years. You can see the list and an explanation of the methodology used to create the list here.
For a similar list you can check out Fred R. Shapiro and Michelle Pearse, The Most-Cited Law Review Articles of All Time, 110 Mich. L. Rev. 1483 (2012).
Thanks to Ted for the update!
