The Illinois State Historical Society has worked hard to open an online store which features literature and hard-goods which are related to Illinois. These are often hard to find or limited run items.

If you have a history buff in your family that is hard to buy for this is your place to shop! While anyone can purchase items we offer additional discounts to ISHS members. Visit our store to browse the current inventory of items, item availability and inventory will change often.
