Pickwick Book Shop 8 S Broadway, Nyack, NY10960 This is one of the last great used bookstores. Jack Dunnigan has been the owner and operator of Pickwick Books on…More Broadway in Nyack since 1975, but the store has been here since the 1950s. Born and bred in Rockland County, Mr. Dunnigan came here with his parents to shop for books as a child. Since buying the store, he has lovingly cultivated a large used book inventory. If collecting first editions is your thing, you will love this bookstore. There's also a great kid's section.
