W: Sure. Do you see the cards?(10)All the books are listed both by title and by the author’s last name according to the alphabetical order. That is according to the arrangement of 26 letters.

M: Oh, I see. It sounds a huge job.
W: Anyway, you can find all of the books listed in the computer and(11)it gives you more information than the card catalogue. It will let you know if the book you are looking for is currently available, and which library to find it if it is not available here.
M: I’ve never used the computer for finding a book. Is it hard to use?
W: No, it’s quite simple. The instructions are there beside the computer. You won’t have any trouble.
M: But then what should I do after I find a book I need?
W: You’ll get a same number both from the card and computer.(12)Write down the number. It tells you where to look for the book on the shelves.
M: Oh, I get it. Thank you very much.
