I took the quiz. I have read at least part about a dozen of them, but most of them I haven't even heard of.
Of course I'm not American so I really don't know what should and shouldn't be on that list, but I did notice the absence of Toni Morrison, Mark Twain and other big names. I would have expected a "classic" like Catch 22 to be there as well, but maybe I'm just showing my age now...
