Here's a trivia question for you lawyers in our reading audience. Which Supreme Court case leads the list of those most-cited, according to HeinOnline's citation metrics? No peeking, now. It's Brown v. Board of Education, followed closely by Roe v. Wade, cited 15, 991 times. Next are Griswold v. Connecticut, Miranda v. Arizona and New York Times v. Sullivan. Reassuringly for those of you who are thinking, "Geez, I didn't need to go to law school to recognize those names," Marbury v. Madison appears at lucky number 13. Marbury v. Madison is the secret handshake of the lawyering guild, as anyone who has ever turned themselves inside out trying to understand, and to explain to their professor, why it's in their Con law book, can attest.
And just to satisfy your curiosity, Lemon v. Kurtzman comes in at number 50, with 4,486 citations.
