W: Good morning, Peter.
M: Good morning, Julia.
W: Do come in. You’ve brought the results with you, I see.
M: Yes, in fact, I completed the survey last week. (22)
W: So, I can hear the criticisms now?
M: That’s right. And perhaps you’ll be able to tell me what can be done about them.
W: I’ll certainly do my best. Well, what would you like to start with?
M: The catalogues. I’m afraid many of the science students complain that they’re incomplete and out of date. They think they’re really bad. (23) Is there anything you can do to improve things there?
W: Oh, yes. We can check all the cards and reprint them where necessary (24), or we can change to a computer system.
M: How much would it cost to do the first?
W: About six thousand pounds.
M: And how long would it take?
W: Oh, maybe three months.
M: And how much would it cost to do the second?
W: Change to a computer system? Oh, about sixty thousand pounds.
M: And how long would that take?
W: Er, nine months, I’d say. About nine months.
M: Thank you. Now... next I’d like to move on to the borrowing facilities. The social science students described these as rather disappointing. They complained that they were only allowed to borrow three books. Most of them felt they ought to be able to borrow more books, perhaps five or six for undergraduates and up to ten for graduates. (25)
W: That may be possible.
M: Also, they’d like to be able to keep the books for a longer period, say three weeks instead of the present two.
W: That also sounds reasonable. I’ll see what I can do.
