The Origin & Many Uses of Shellac, by R.J. Wakeman

Not only is there an exhaustive explanation of the various ways shellac was used in records over the years, but its use in diaphragms, cabinet finishes, and other products is presented as well. Even the particular trees and insects are covered whose symbiotic relationship results in this wonderful product!
