Abstract
Climate control in archives can be managed very differently from that in other buildings, but very often standard technology, and reliance on standard specifications is applied. This article is a re-investigation of how best to control the climate in archives, based on the chemistry of decay and the physics of the atmosphere, by at first discarding the pedantic strictness of the archival standards but then paradoxically showing that they can indeed be attained by very simple means.
