What does the man need from the library?

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.
