BL Preservation Cold Store at Vindon- the cold rooms • rooms designed & built on site • shelving & ducting is grade 304 stainless steel • vertical rear plenum located at the rear of each room • air is attracted at high level through this plenum by fan(s). • air is then passed over the cooling coils to floor mounted ducting system where the “conditioned” air passes into the room through adjustable vents. • shelves are perforated for maximum exposure to conditioned air

  22. 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
