This book by the National Committee to Save America's Cultural Collections states right off in its introduction its intention of focus toward private collections - not toward institutions such as museums, archives or research libraries. Those institutions of cultural "memory" already have their own departments geared toward and working on conservation and protection of cultural artifacts.

The result is a series of sections designed around types of objects such as library/archival, ethnographic materials, stone, textiles and works of art on paper. Each section covers generally issues such as relative humidity (RH) ranges for each types of object, permissive temperatures and the how to manage light so it doesn't damage anything.

This is an older book. 21 years old now. But the information contained therein is helpful for those of us who collect things and want to do whatever we are able to keep them lasting as long as possible in the best possible state.
