You are in the library. You are going to leave, but a message alerts all the people in the place. There is a blizzard and no one can get out. There is a power outage, the lights go out. By the time the blizzard stops, all the exits are covered in snow. You are trapped! The entire city is the same, and the emergency services are doing what they can to free the different buildings, but it could take days to reach you. The days are cold, and the nights are even colder! There is no choice but to start burning books. What books, genres or sections would you start burning? What knowledge do you not mind losing? What books would you defend from being burned?
