The preservation impact Moving the microfilm collection into the new storage suite at Vindon has had a major impact on the preservation of the collection The doubling of free acidity in actively degrading film Increased from 10 years to 200 years The development of acidity in films not actively degrading Increased from 80 years to 350 years Natural age rate (non-acetate) Reduced from moderate to very slow Preservation Index (PI = units = years, the higher the PI the better conditions are for preserving organic material) Increased from 63 years to 488 44
