The Carnegie Library Building, currently known as the Navy Supply Corps School Museum, is located at 1401 Prince Avenue (Tax Parcel No. 11-4-C4-I-000).

This yellow brick building is a highly ornamented and eclectic example of the Neoclassical style. An abbreviated second-story with clerestory windows crowns a tall first-story. A significant decorative element is the wide entablature, comprised of an architrave, a frieze of triglyphs and metopes, and a projecting cornice with mutules. Closely spaced palmettes appear along the cornice. Woodwork also includes heavy mullions and an entrance pediment, supported by a pair of Doric columns in antis and ornamented with dentils and antefixes. Consoles support a smaller yet similar pediment over the doorway, which is decorated with paterae and lighted by oval panes of plate glass. Eight colossal columns with Temple-of-the-Winds capitals delineate the octagonal lobby. A small garden, developed as a memorial to "war lost" from the Navy Supply Corps, is located to the rear of the building.

Philanthropist George Foster Peabody contributed $25,000 to the Andrew Carnegie Fund. Despite his having received little formal education, Peabody made his fortune as a banker and developer of the Edison Electric Illuminating Company, later General Electric. After he retired in 1906 to pursue philanthropy full-time, the University of Georgia and the Normal School were among his eclectic interests. Through his gift, the State Normal School constructed the library building in 1910.

The Carnegie Library Building is listed on the National Register of Historic Places (November 11, 1975).
