Interactive or movable books are unusual artifacts, hybrid objects that look like books but are actually part story, part images, part game or toy. They assert a strong presence in the children’s books market, where they range from simply devised, sturdy board books to spectacular pop-up books with several platforms of movable components. Movable books are also found in digital apps designed for children, from adaptations of classic books to “born” digital artifacts that have no previous material existence. These artifacts include app-based movable books that often evoke the form of paper artifacts and invite children to interact with them in a similar manner.
