"Some Cardinal Principles  of Librarians' Work." Public Libraries / Sam Walter Foss.
Chicago, IL: Public  Libraries 14 77-81, 1909.
“Don't stay in the  library all the time yourself and stagnate in the musty atmosphere of your dead  books. Be a public and not a private man. Get out and feel the dynamic thrill  that comes from contact with live men. The club, the exchange, the street, the  philanthropic and economic organizations that are feeling out for the betterment  of mankind are the places where the librarian should be found frequently. He  should be the best known man or woman in the city.”
