There’s a secret branch of the New York Public Library in the subway.
The 51st Street 6 line subway station is home to the Terence Cardinal Cooke-Cathedral branch of the New York Public Library. Librarians at the location report that they’re usually visited by the same partons, frequent commuters who are looking for something to read during their daily train ride. Like all New York librarians, though, they’re happy to answer research questions — usually about how to work the Metrocard machine. The library is currently closed for repairs, but you can visit it when it reopens in September if you need a good book for your ride home … or need to figure out how to get home.
