  2. Ideal levels are 68-72° F, with 40-50% RH. Monitor temperature and humidity levels. Excessive fluctuations in temperature and relative humidity can be particularly damaging to book
  3. Choose a room with decent airflow, and don't store books directly under or over a heating or cooling vent. A ceiling or oscillating fan can help regulate airflow. You want to keep the humidity below 60% (archives aim for no more than 35%). Above 60% humidity mold spores can form, and once present mold can quickly spread through the air
  4. Oppositely, too little humidity can dry out books, so use a humidifier in the drier winter months. Dust is also a magnet for moisture and mildew, so periodically dusting the tops of books will keep them clean.
