Beinecke Rare Book and Manuscript Library

The Beinecke Rare Book & Manuscript Library is the rare book library and literary archive of the Yale University Library in New Haven, Connecticut. Situated on Yale University's Hewitt Quadrangle, the building was designed by Gordon Bunshaft of Skidmore, Owings & Merrill and completed in 1963. Established by a gift of the Beinecke family and given its own endowment, the library is financially independent from the university and is co-governed by the University Library and Yale Corporation.

The library's iconic building reopened in September 2016 after an 18 month closure for major renovations, which included replacing the building's HVAC system and expanding teaching and exhibition capabilities.

A six-story above-ground glass-enclosed tower of book stacks is surrounded by a windowless rectangular outer shell, supported only on four massive piers at the corners of the building, which descend 50 feet (15 m) to bedrock. The outer walls are made of translucent veined marble panels quarried from Danby, Vermont, which transmit subdued lighting from outside, while providing protection from direct sunlight. At night, the stone panels transmit light from the interior, giving the exterior of the building an amber glow. The outside dimensions have "Platonic" mathematical proportions of 1:2:3 (height: width: length). The building has been called a precious "jewel box", and also a "laboratory for the humanities". The Modernist structure contains furniture designed by Florence Knoll.
