听力原文：W: Hi. Can I help you? M: Yeah, I'm looking for a reference book. W: OK. Do you know the title? M: Well. I'm not exactly sure what I'm looking for. I need information on European demographics. W: OK, do you just need population statistics, like, total population, male-female ... real basics for demographics? M: Yeah. Population, literacy rate, uh, let's see ... life expectancy by gender, like if women tend to live longer than men ... things like that. W: OK, well, I'm pretty sure you can get most—if not all—of those statistics from an atlas. M: Yeah, but I'm kind of looking for it by city, not by country. W: I see ... M: Well, do you know if there are any other reference books I can use for this? W: Hmmm. Maybe you could tell me what this is for maybe I can help you better. M: OK. Geography with Professor Miller and it's sort of an analysis of, uh, urban areas, a comparison of population trends and economic indicators, social indicators ... W: Did your professor give you any ideas on where to look? M: No. She just gave us the assignment and I figured I could find what I needed here without too much of a problem. W: Yeah, it should be easier than this. I mean, I know there's one for North American cities, but I don't think that'll be a big help. M: Nah. W: Let's go over to the reference section. Let's take a look around that area and see if anything looks promising. What does the man need from the library?
