M: Hi, Vivian. What are you doing here?
W: Hi, Steve. I’m having a bit of trouble finding some of the stuff I need.
M: What’re you looking for?
W: Well, I’m just trying to find out something about the use of steel in building construction.  Do you have any idea?
M: Frankly, I don’t know much about this.  What about the library? There’s a database on the computer, and most of the stuff you need is catalogued.  You can find it somewhere.
W: Yes, but that’s the easy part! Then you have to find the book you want on the shelves, and you often find that it’s out already.
M: I know what you mean ! Then you have to line up to borrow it, if it’s CTL.
W: CTL? What’s CTL?
M: It means "confined to library" : you know, it means you can’t take it out.  You have to read it in the library.
W: It seems easy, doesn’t it? But you have to reserve it, and then you may want to photocopy bits of it, or make notes--and there never seems to be enough time.
M: Hmm! In your shoes, I think I’d have a word with our tutor.
W: I think I’ll do that! Thanks! See you later. Bye!
M: See yah! And good luck !
