“Be a little careful of your Library. Do you foresee what you will do with it? Very little to be sure. But the real question is, What it will do with you? You will come here & get books that will open your eyes, & your ears, & your curiosity, & turn you inside out or outside in.”
—Ralph Waldo Emerson (1803–1882)
“Time has no divisions to mark its passage, there is never a thunderstorm or blare of trumpets to announce the beginning of a new month or year. Even when a new century begins it is only we mortals who ring bells and fire off pistols.”
—Thomas Mann (1875–1955)
