Who is the man talking to?

(A = woman, B = man)
A: You’ve been using the Online Catalogue for quite a while; is there anything I can help you find?
B: I’ve got to write a paper about Hollywood in the 30s and 40s, and I’m really struggling. There are hundreds of books, and I just don’t know where to begin.
A: Your topic sounds pretty big. Why don’t you narrow it down to something like. .. uh. .. the history of the studios during that time?
B: You know, I was thinking about doing that, but more than 30 books came up when I typed in "movie studios. "
A: You could cut that down even further by listing the specific years you want. Try adding "1930s" or "1940s" or maybe "Golden Age. "
B: "Golden Age" is a good idea. Let me type that in. . . Hey, look, just 6 books came up that time. That’s a lot better.
A: Oh. .. another thing you might consider. .. have you tried looking for any magazine or newspaper articles?
B: No, I’ve only been searching for books.
A: Well, you can look up magazine articles in the "Reader’s Guide to Periodical Literature". And we do subscribe to "The Los Angeles Times. " You might go through their index to see if there’s anything you want.
B: Okay. I think I’ll get started with these books and then I’ll go over the magazines.
A: If you need any help, I’ll be over at the Reference Desk.
B: Great, thank you.
