The New York Public Library for the Performing Arts isn’t your typical library, although I do go there to read and take advantage of their WiFI and, um, use their very clean restrooms.

Anyway, this library is home to one of the world’s most exhaustive collections of circulating, reference, and rare archival materials in the performing arts field. It also houses a large volume of non-book collections. Materials such as videotapes, sheet music, stage designs, rare films, posters and photographers can be found among its stacks and archive rooms.

“Le Guichet,” a metal sculpture by artist Alexander Calder is erected right outside the main entrance of the library. The sculpture is supposed to be an abstract interpretation of a box office that features a hand reaching through an irregular-shaped hole (the ticket window). Do you see it?
