I have seen several photographs of this wall in Chattanooga Public Library. Big thanks to the people who have photographed it for those of us who have not been there.
I like this wording because it reassures the clients - you are in the right place. Implicit in this is that the folk at the library (with their various qualifications, skills and experience) are there to help you - whatever your questions, interests or service requirements. It is is a big ask, but - as a client, you are in the right place. There will be people who serve, help, inform...and do this with good grace and using their many skills. I like the hopefulness and the reassurance.
