The question asker didn't say he was interested in reading the books people listed, but what if he was?
This question and it's answers is isomorphic with a request for recommendations for similar books, which is a question type that is getting close because scifi "isn't a recommendation service."
(Btw, I don't think it should be closed, because to mention a book, without specifically condemning it is to recommend it. But if we don't mention books, we can't talk about science fiction.)
UPDATE: 20% of the front page questions are of this type. A bit higher if you include the already closed questions. So 1/5 of all newbie questions will get closed. When I started as a naive newbie on SO, I didn't have anything near a 20% close rate
