Encyclopedia of Global Resources part 134 provides a wide variety of perspectives on both traditional and more recent views of Earth's resources.

Research into uses for tin continues. Because of its unusual physical properties and because it is nontoxic tin will continue to be an important metal. Jay R. Yett Further Reading Evans Anthony M.
