May I help you?
I would like to find this book.
Is there a problem?
I don't think you guys have it.
You should look it up on our computer.
I did that.
What came up?
It should be on the shelf, but I didn't see it.
I can try to get the book from a different library.
I didn't know you could do that.
I will call you when I find it.
I appreciate your help.
