The Museum Environment is in two parts; Part I: intended for conservators and museum curators and describes the principles and techniques of controlling the environment so that the potentially damaging effects of light, humidity and air pollution on museum exhibits may be minimised. Part II: the author brings together and summarises information and data, hitherto widely scattered in the literature of diverse fields, which is essential to workers in conservation research.

Since the timely publication of the first two editions of this book in hardback, interest in preventive conservation has continued to grow strongly making publication of this paperback edition all the more welcome. Those whose responsibility it is to care for the valuable and beautiful objects in the world's collections have become increasingly aware that it is better to prevent their deterioration, by ensuring that they are housed and displayed in the best possible environmental conditions, than to wait until restoration and repair are necessary. The changes for the second edition have been mainly concentrated in the sections on electronic hygrometry, new fluorescent lamps, buffered cases, air conditioning systems, data logging, and control within historic buildings. A new appendix, giving a summary of museum specificiations for conservation, provides a useful, quick reference.
