The Island Bookstore began as a small antiquarian store with a small retail space above Doud's market over 40 years ago. Today there are two locations, one on Mackinac Island and the other in Mackinaw City, serving the Straits of Mackinac area. The two stores are open from May through October, and you can visit the store online all year long. The Island Book Store will keep you in touch with new Mackinac and Michigan releases that your local shop might not get as excited about as they do. They specialize in Mackinac Island and Northern Michigan items, but are also a full-service book store.
