M: Hello, I’m looking for a reference book.
W: Do you know the title?
M: Well, that’s the thing. (12)I’m not exactly sure about the title. I just need, uh, information on European population.
W: OK, do you just need population statistics, like total population statistics, total male and female population?
M: Yeah. Population, literacy rate, uh, let’s see…life expectancy by sex, 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 a book of maps. I can tell you where to find one in the reference section.
M: Yeah, but I’m kind of looking for it by city, not by country…
W: Uh-huh.
M: Well, do you know if there are any other reference books I can use for this? To find the statistics by city?
W: City, you say. (13-1)Any particular part of Europe? Eastern, western, southern…
M: (13-2)No. Pretty much all across Europe.
W: All of Europe. Hmm. You know, (14-1)maybe you could tell me what this is for, I mean, maybe if I know, I can help you better.
M: (14-2)Yeah, OK. Geography with Prof. Miller and it’s sort of an analysis of urban areas, a comparison of population trends and uh, economic indicators or social indicators, I guess.
W: OK, well, there’s something called (15-1)The Population Yearbook, but I don’t think it’s gonna do it by city either.
M: (15-2)Yeah that’s just by country. I’ve read that one.
W: I’m sorry. But tell you what, let’s go over to the reference section. Let’s take a book around that area and see if any other book looks promising.
M: OK, thank you.
