| 'Pilgrim's Progress Effect. In the Massachusetts Colony of - what was it! - seventeenth-century Old Earth, every decent family had to have a copy in the household. But, my heavens, no one had to read it.'
SOOOOOOOooooo many books fall into that category these days (or any days, I guess...) As for whether or not it should be included... you'd have to let in at least half the western canon if you did. The modern fantasy genre stretches generally back to Tolkien, and arguably no further than Morris. So while technically it fits, few fantasy/sf readers read anything so old unless forced to in school.
I'm sure any number of the Unplaced writers surpass Paolini.
Judging by the amount of shelfspace Jordan has had in bookstores over the years, and the sheer number of them I see in the thrift stores, I'd wager Jordan's ahead of Brooks, though Brooks isn't far behind.
