Only 7 Plots

So I'm reading this book and at chapter 8 I'm wondering when the author is going to get to the point. Turns out the book has 45 (!) chapters. I click over to Amazon to see how many pages it has (528!) and I stumble across a review on a different book that says there are only 7 plots in all the world's stories.

What? I must know more about this and google it. Wikipedia lets me down (all I want is a list), but I found the old and new descriptions here.

Old ones:

Man vs Man
Man vs Nature
Man vs Himself
Man vs God
Man vs Society
Man in the Middle
Man meets Woman

New ones:

Overcoming the Monster
Rags to Riches
The Quest
Voyage and Return
Comedy
Tragedy
Rebirth

I love this quote from that same blog post:

"Star Wars is a rags to riches quest where the hero overcomes the monster on a voyage and return while the Villain experiences rebirth at the end."

No wonder it's popular, it's got them all in there somewhere.

This post, on the other hand, mentions 20.
