听力原文：W: Good afternoon! I'm a newcomer. I wonder If you could give me some information

M: I'd be pleased to. What can I do for you？

W: Suppose I want to find a book "Gone With The Wind" by Margaret Mitchell, would I look under Margaret and then under Mitchell until I come to the one who wrote the "Gone With The Wind" or would I simply look under the title through the catalogue myself？

M: Do you see those desk-top computer terminals over there？ We now use them to locate our books. We think it's more efficient than the old card catalogue system. Come on, I'll show you how to use it. You decide what book you want and pick the microfiche with that letter on it. It's all in alphabetical order. You can know the name of the book, the name of the author or subject. They're all lumped together on the same sheet.

W: That sounds easy enough. Suppose I want to borrow "War and Remembrance" by Herman Work.

M: You could look under "W" for the title, then we'll look on the "H" sheet for the author. Turn on the light, then move the microfiche, and there it is. The "W" after the library code number tells you that it's here at the back branch of the library, rather than at one of our other branches.

W: Today, I just want to find a novel for some light reading. It strikes me that this novel "The Grapes of Wrath" by John Steinbeck is what I should like to take.

M: You are perfectly right to decide upon that book It's very much in demand. Please fill out this card. Do you have any identification which shows your new address？ I need to see something that verifies that you're a resident of the country ... All right now. I'll give you a list of all the branches before you go. These books may only be used here, and no one is permitted to borrow them.

W: I'll be here for five years, so I'd like to learn to use the library as efficiently as possible. I wonder if someone might have time to show me around.

M: With pleasure. These shelves right next to us have our latest acquisitions of fiction and nonfiction The older fiction books are in alphabetical row according to the author's last name. Stop by the desk on your way out to check your books and to pick up a brochure description of all our services.

W: Thank you very much for your help. I've noticed that your periodical section is quite complete. I think I'll explore the whole library on my own in order to acquaint myself with all that you have told me.
