From The New York Sun today:
“The cast-iron columns in the first-floor auditorium support the library floor, while iron trusses in the attic support the library ceiling, the attic floor, and the roof. The loftiness of the space and its exquisite woodwork take your breath away. The gorgeous carved-wood fluted columns, with Corinthian capitals, encase iron columns that support the galleries that encircle the room. It is everything a library should be.”
