Arguably the most beautifully decorated building in the United States, the Library of Congress building (recently renamed the Jefferson Building) is celebrating its one hundredth anniversary this year after an eighty million dollar restoration that returned it to its original state. Designed by John L. Smithmeyer and completed in 1897 at a cost of under seven million dollars, the building is enhanced by the art of over forty sculptors and painters whose ranks include such notables as Herbert Adams, Kenyon Cox, Edward Clark Potter, Louis Saint-Gaudens, and John Quincy Adams Ward. The planning and construction are detailed in John Y. Cole's essay, followed by discussions by Henry Hope Reed, Richard Murray, and Thomas P. Somma of the decorations, paintings, and sculptures. The volume concludes with a study of the restoration by Barbara Wolanin, a chronology, a glossary of architectural and decorative terms, and a biographical dictionary of all the artists, architects, and designers who worked on the building. Throughout, noted photographer Anne Day's color images enhance this splendid book.
