In the article "King Copper" (EW Sept. '98, p. 42), the copper pricing chart illustrates the changes in copper pricing from 1993 to 1998. The information in this chart came from The Copper Journal, published by J.E. Gross & Associates, Inc., Huntington, N.Y.

The article "Who Owns Whom in Wire World, " (EW Sept. '98, p. 34) contained an error regarding the growing family of wire and cable companies owned by the Marmon Group, Chicago, Ill.
