Famous quotes containing the words library and/or congress:
“... the subjective viewpoint is the only one to use regarding a library. Your true library is a collection of the books you want. You may have deplorably poor taste or bad judgment. Never mind. Correct those traits before you exchange your books.”
—Carolyn Wells (1862–1942)
“What have Massachusetts and the North sent a few sane representatives to Congress for, of late years?... All their speeches put together and boiled down ... do not match for manly directness and force, and for simple truth, the few casual remarks of crazy John Brown on the floor of the Harper’s Ferry engine-house,—that man whom you are about to hang, to send to the other world, though not to represent you there.”
—Henry David Thoreau (1817–1862)
