I know what you're saying - what the heck is the Schwartzman Building? Well, that is the official name of the main building of the New York Public Library.
Whatever you call it, this building is awesome. Back in the day, I would go there to do research, spending the whole afternoon in the Rose Reading Room. Just climbing the steps all the way to the Rotunda, with its ceiling mural of Prometheus stealing fire from heaven, can be fun.
I also always loved the free exhibits they have hosted over the years. When we visited most recently, the exhibit was on the history of children's literature. Splendid!
