of staircases continues to the McGraw Rotunda on the third floor. Each staircase passes through another landing, which has a domed ceiling and a hanging chandelier. Other spaces The Wallace Periodical Room in room 108 has been named for Reader's Digest founder DeWitt Wallace since 1983. It consists of current issues from 200 periodicals and 22 newspapers. The current design of the room dates from a renovation in the 1980s. The Periodical Room contains 13 murals of scenes from the history of New York City, which were designed by Richard Haas, The original design included cast-iron radiators, which were replaced with an air-circulation system under the windows. In addition, the room contains bronze chandeliers and sculptured ceilings. Behind Astor Hall's information desk is the Gottesman Exhibition Hall. It served as the Main Branch's primary display area from 1911 to 1942 and was subsequently divided into offices. The space reopened in 1984. The Gottesman Exhibition Hall is made of Vermont marble and is accessed by large bronze or wrought-iron doors. The room measures across and high. The room contains Vermont marble pilasters and columns, as well as bronze and leaded glass chandeliers hanging from a carved-oak ceiling. The ceiling largely contains sunken panels with various Renaissance-style decorations, but the outer section of the ceiling has octagonal coffers. The floor includes a grid of circles and rhombuses. Second floor The second floor contains the Jill Kupin Rose Gallery, which contains ongoing exhibitions. This floor contains several small rooms extending to the north, west, and south. One of these is the Wachenheim Trustees' Room, which contains wood paneling, parquet floors, and a fireplace made of white marble. Originally, this level contained director's and assistant director's offices; the Slavonic, Jewish, and Oriental Collections; and rooms for science, economics and sociology, and public documents. The former science room at room 225 is now the Cullman Center, while room 228, the former economics and sociology room, has been split into two rooms. As on the first floor, the second floor's north–south corridor extends the entire width of the floor, but the ceiling was made of plaster to save money. Third floor The McGraw Rotunda is on the east side of the building's third floor. The Print Gallery extends south from the rotunda; one publicly accessible room, the Wallach Division, is adjacent to the gallery. Similarly, the Stokes Gallery extends northward, with the Berg and Pforzheimer Collections
