The Library for the Performing Arts at Lincoln Center in New York City. I've spent quite a bit of time here over the years researching and took these photos after leaving yesterday (it's a great place to write, especially at the research division on the 3rd floor- lots of natural light and much quiet). This is the second floor - where the circulating collection is located - which looks out over Lincoln Center plaza.
A few step down and you are out onto the plaza. The signage let's you know where you are. But I can't tell you how many times I have been asked when on the plaza where the library is. Ok. So it seems to be tucked away at the back of the plaza. But the name is in red! Hard to miss, I think. A matter of looking but not seeing? In any case, turn to the left and you find yourself smack up against the north side of the Metropolitan Opera.
Walk east along the building and you find yourself at the front where the gift shop and box office is located.
Keep walking out onto the plaza you might run into a group of guys (singers I think) having their picture taken. Avery Fisher hall is on their right. This is one of the great spaces in New York.
