Maybe the works of Plato and Aristotle in the library could be placed in a glass case just in case anyone might be offended by their overt frontal display on the shelves. They could then be taken out at certain times on special occasions when someone felt prompted to look into them after which they could be placed back in the case and covered with special felt coverings. A similar reliquary storage could be worked out for the works of Shakespeare, John Locke, Thomas Jefferson, et al., or any offensive issues of National Geographic with which some people might object to on the symbolic level.
