On the lighter side

NPR polled for the hundred best science fiction and fantasy books.

Let's see: I've read 9 of the top 10, 14 of the top 20, 20 of the top 30, 30 of the top 40 and about half from there on. Some clearly deserve the slots (Tolkien, Ringworld, and so on) and some are pretty mixed (the whole Dune series? not just the first?), and some I wonder about (a book by Moorcock is on the list? seriously?). Quite a few recent authors show up--I wonder how many would still be on such a list 30 years from now.

If people are still making such lists 30 years from now, I'd suspect "Stranger in a Strange Land" and "The Handmaid's Tale" will be nowhere as their respective politics ages away, also "2001" where the movie was better than the book.

Your guesses as to which will be absent?
