Rooms where library material is stored and shelves on which library material is kept should be properly ventilated. Air movement removes off-gassing of organic materials and prevents a build up of pockets of high relative humidity which can lead to outbreaks of mould.

It is not only essential to have adequate ventilation but the air entering and circulating in storage areas should be free from air pollutants. Air pollutants vary greatly in nature, from gases to particulates.
