The Chadron Public Library, built in 1913 and renovated in the 1960s in Chadron, a small city but the largest in the northwest corner of Nebraska, south of South Dakota and east of Wyoming. The two-story library is one of the smaller of more than 2,500 Carnegie Libraries, endowned by New York industrialist and philanthropist Andrew Carnegie in the early 20th Century.
