So 6 out of 50 (I must have miscounted before when I commented on Sarah's post). I'm surprised it's so low given I did take an entire class on Sci-Fi lit in college. But I suppose that focus was more on short stories. There are a few on here I've wantched to check out for awhile (Do Androids Dream) but I honestly haven't even heard of a lot of the titles on here.
