621.972, One Good Turn: A Natural History of the Screwdriver and the Screw, by Witold Rybczynski (2000).
623.451190973, 109 East Palace: Robert Oppenheimer and the Secret City of Los Alamos, by Jennet Conant (2005).
624.1821092273, High Steel: The Daring Men Who Built the World’s Greatest Skyline, 1881 to the Present, by Jim Rasenberger (2004).
