Top 10 cited authorities

Alright. So who are the top 10 authorities cited in American academic journals?

They are in the following order:
1. Karl Marx
2. V. I. Lenin
3. William Shakespeare
4. Aristotle
5. The Bible
6. Plato
7. Sigmund Freud
8. Noam Chomsky
9. Hegel
10. Cicero

I chanced upon this while viewing the video Rebel Without a Pause. What struck me most was I almost always believed that it was Marx, Bible and Chomsky in that order. It still is in that order. But well, I had no idea some others too went in between. Especially, Lenin at No. 2!
