 Robinson Crusoe is an example of a late 19th century hinge book or flap book, one of the simplest mechanical structures and earliest examples of mechanical books aimed at children. I do want them to keep in mind that it's a reproduction, it's not the original from the 19th century, but it represents exactly what those books looked like and the experience of reading and moving them would have been like for people at the time. The Robinson Crusoe is in the collection because it provides an example of that early movable structure geared particularly at children.
