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 .
