2. The Book Cellar, 1465 York Avenue

The Book Cellar hidden bookstore

Love library books so much you want to keep them forever? Stop into the Book Cellar, concealed in the back of the NYPL’s Webster branch on York Avenue on the Upper East Side. This little spot is the book equivalent of a 24/7 extensive garage sale. The amount of paperback volumes that fit into the basement space is a near miracle, and the prices are unbeatable. While visiting, we heard a woman buying a whole armful of novels comment to the cashier, “These would be the price of a single book from Barnes&Noble!” She’s right. The Book Cellar is also great for donations, so if you love the finds, you can also give back. Give cheap books, and ye shall receive.
