Where is the library?

M: Could you tell me where our library is?
W: It’s in the building next to ours.
M: Is it the big white one?
W: Yes, a great number of books are kept in the library. It has books in Chinese, English, Russian, German, French and many other languages.
M: Are there any reading rooms in the building?
W: Of course. How can it be a library without reading moms? There are quite a number of reading rooms with newspapers and magazines in them on the first and second floors.
M: When is it open?
W: It is open every clay except Sunday.
M: I see. Library is always a busy place. I want to borrow an English hook. I hear "The Adventures  of Tom Sawyer" is very interesting. Have you read it?
W: Yes, I enjoyed it very much. It’s worth reading.
M: I wonder if you could tell me how to look it up in the card ’catalogue?
W: Certainly. It is written by Mark Twain. So you can either look it up under "A" for the writer, or "T" for the title.
M: Thank you for your great help to me. How long can I keep it?
W: You’re welcome. You can keep it for two weeks. When it is due, it should be returned.
