But the personal relations of the librarian and her assistants with the public belong as much in the third section of our subject as in the second. The importance of them cannot be exaggerated. I am not sure that I should not prefer a sunny-faced, pleasant-voiced, intelligent, good-tempered assistant in a tumble-down building with a lot of second-hand, badly arranged books, rather than the latest Carnegie library stocked with literary treasures if these had to be dispensed by a haughty young lady with monosyllabic answers and a fatigued expression. I know of no more exasperating duty than that of continually meeting a library public--and I know of no pleasanter one. For the public is just you and me and some other people, and like you and me it is various in its moods. The mood of the public in a library is often a reflection of that of the librarian. The golden rule here is direct personal contact; and don’t forget the last syllable--tact. Don’t force your services or your advice on people that neither wish nor require them, but don’t forget that you may have pleasant, intellectual intercourse without offering either aid or advice. When an aged man who knows more of literature than you dreamed of in your wildest visions wants “The Dolly dialogues,” don’t try to get him to take “Marius the Epicurean” instead. But if you get into the habit of talking with him it may make the library seem pleasant and homelike to him, and, besides, he may tell you something that you do not know--that is a not remote and certainly fascinating possibility.
