Mr. Woodbury, a physical scientist with the U.S. Bureau of Mines, Branch of Metals, had 25 years of mining and civil works geotechnical experience upon becoming the Bureau's lead specialist in 1982. Domestic survey data were prepared by Eraina Dixon and Lisa Conley, mineral data assistants; international data were prepared by Theodore Spittal and Virginia Woodson, international data coordinators. Domestic data for lead are developed by the U.S. Bureau of Mines from five voluntary surveys. Typical of these are the combined secondary producer and consumer surveys, both monthly and annual.
