Conical skylight filters sunshine into Garinger High School library, Charlotte. Folded panels of trans lucent plastic, suspended on a steel frame, form the umbrella-rib pat tern. Stacks surround the sunken reading room. Completed in 1959, the school serves as a showplace of the Charlotte-Mecklenburg school system, North Carolina's largest. Saddle-shaped roof covers the J. S. Dorton Arena at Raleigh. Cables stretching between two 90 foot-high parabolic arches cradle the top, strong enough to bear the weight of a 60-inch snowfall. The glass-walled structure seats 9,500 for conventions, exhibits, and ath letic events.
