This article covers much the same ground as the reference above, but using different examples. Fundamentals of moisture in air. This is a concise summary of the physics of water vapour in air. It is intended as a reference page rather than a tutorial. The Mollier diagram and the psychrometric chart. An explanation of the derivation of the graphical presentation of water vapour properties.
www.padfield.org/tim/cfys/mollier/moll1.php How air conditioning works. This is essential reading. It describes the fundamental processes of air conditioning, from window mounted boxes to whole building ducted air supply. The process by which absorbent materials buffer the RH of their surrounding space is described in this article which is specifically about the interaction between water vapour and paper. It explains why archives containing abundant cellulosic materials buffer the room climate so well that immediately reactive RH control is unnecessary.
