While the Wythe's collection is indeed playful (care to read an autobiography by Snooki? It's here), the NoMad's collection and library itself are a tad more highbrow. In fact, the collection of books at the NoMad was curated by Thatcher Wine, owner of Juniper Books in Boulder. He explained:
"I'm the one who curated the book collection for the library there - all 3,500 books, individually handpicked book by book, working closely with the developers, designers, and restaurant operators.
Everything on the lower level was chosen by subject and is organized that way - entire sections of books about France, New York, music, wine & food, etc."
So basically: go to the Wythe to play Connect 4 and learn about Snooki's rise to reality fame, or cozy up in the NoMad's Beauty and the Beast-esque, wood-paneled reading room with a volume on New York's history. The choice is up to you!
