West 40th Street Carnegie Library Branch, 1914.

Completed in 1913 (relatively late for a Manhattan Carnegie) the West 40th Street Branch was designed by Cook & Welch. The architects had designed a number of other Carnegie libraries, including the Seward Park Branch.

The neighborhood that surrounds is drastically different from when the building was constructed. Once flanked by four and five-story tenements, today the building is surrounded by the ramps and infrastructure of the Lincoln Tunnel, constructed in the mid 1930s. The library was decommissioned at some point in the late 20th century and was attached to a newer structure that was part of Covenant House, a charity that combats teenage homelessness.

In 2020, the library was demolished to make way for redevelopment of the block.
