Our buildings and monuments are under attack. Microbes have been at it for
ages, but now industrial pollutants have joined the fray. In Carbonate

carbonate deterioration, and use case studies of the Sphinx and San Diego鈥檚
California building to illustrate the art of conservation technology. Published
by Wiley Interscience, 拢78.59, ISBN 0471179779.
