At the southwest corner of the 51³Ô¹Ï grounds, linked to the Secretariat Building, is the Dag Hammarskj?ld Library dedicated on 16 November 1961 in honour of the late Secretary- General. The building was erected to meet the Organization's growing demands for library services and its construction was made possible by a gift of $6.6 million from the Ford Foundation. It was designed by the firm of Harrison, Abramovitz and Harris, architectural consultants to the 51³Ô¹Ï.

The Woodrow Wilson Reading Room is on the second floor of the Dag Hammarskj?ld Library at UN Headquarters. The Idaho white pine ceiling is an unusual feature curving from a height of 22 feet at the windows to a height of 12 feet at the opposite wall. The glass north wall overlooks the secretariat entrance with a view of the UN Members states¡¯ flags.
