A recent (Season 5) Malcolm Gladwell Revisionist History podcast reminded me that there is a long history of elections by lottery. (Revisionist History, Malcolm Gladwell, The Powerball Revolution, Season 5, Episode 3.)
If you want to conduct a thorough literature search of the topic Election by Lottery or Lottery Voting, you’ll need legal, political science, history, and other indexes – indexes and treatises that go back many centuries (i.e. pre-Google). You will also need to search primary sources of law, again back to the beginning of recorded time.
But if you want a basic introduction to the topic, “The Google” and the Scholarly-ish Google will suffice, along with “The Wikipedia.”
