The life expectancy of collections is significantly affected by the environmental conditions in which they are stored. Environmental problems in buildings can cause significant damage to collections. Poor conditions can lead to damage to hundreds or even thousands of items at one time, each of which may need expensive individual repair.
Knowing the environmental conditions in a library or archive is essential for planning the best strategy for the preservation of collections and for targeting your resources effectively.
This booklet from the British Library Preservation Advisory Centre provides guidance on environmental management to help you preserve your books and documents for as long as possible. This guide concentrates specifically on temperature and relative humidity.
