Be careful what you ask a librarian for. Prior to a site visit to a client library at a major university I ended the conversation with a casual statement in an attempt to get directions and an address for the meeting, "OK. I'll be on your doorstep about 9 AM Monday. If you can email your coordinates to me, I should be able to find you."
The next day I got an email saying simply:
Latitude: 35.910561 Longitude: -79.044186
Coordinates: 35.910561, -79.044186
