answer: #Person2# is struggling to choose the books about Hollywood in the 30s and 40s. #Person1# suggests he narrow the topic down by listing the specific years he wants. #Person1# tells #Person2# he can look up magazine articles.
documents: #Person1#: Sir, you've been using the online catalogue for quite a while. Is there anything I can do to help you?
  #Person2#: Well, 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.
  #Person1#: Your topic sounds pretty big. Why don't you narrow it down to something like.., uh... the history of the studios during that time?
  #Person2#: You know, I was thinking about doing that, but more than 30 books came up when I typed in 'movie studios'.
  #Person1#: You could cut that down even further by listing the specific years you want. Try adding '1930s' or '1940s' or maybe 'Golden Age'.
  #Person2#: 'Golden Age' is a good idea, Let me type that in. Hey, look, just 6 books this time That's a lot better.
  #Person1#: Oh, another thing you might consider. Have you tried looking for any magazines or newspaper articles?
  #Person2#: No, I've only been searching for books.
  #Person1#: Well, you can look up magazine articles in the Reader's Guide to Periodical Literature.
  #Person2#: Okay, I think I'll get started with these books and then I'll go over the magazines.
  #Person1#: If you need any help, I'll be over at the Reference Desk.
  #Person2#: Great, thanks a lot.
