听力原文：M: Excuse me. I wonder if you could help me. The reference librarian at the main library suggested I come here. W: What can I do for you? M: Well, I'm working on a term paper about the influence of television on recent presidential elections. I found Some books I need at the main library, but I was told that the library here at the graduate school had more specialized materials. W: Of course it depends on what you want, but We do have a large number of journals. You'll probably have to do a lot of digging. It may take some time. We also have quite a few newspapers on microfilm. M: I think I've come to the right place. How can I find out which journals you have? W: I can give you a list of all of them. But if you want to search by author or by subject you. can use one of the computers over there in the corner. M: What if I run across a reference that isn't available here? W: You can request any outside material just by typing your request into the computer. M: You mean you can get material from other universities? W: Not only from other universities, but from virtually any public or private library in the United States. The only limitation is that outside materials cannot be checked out. (30)
