Dorothy and the Wizard in Oz is the fourth book set in the Land of Oz (though most of the action is outside of it) written by L. Frank Baum and illustrated by John R. Neill. It was published in 1908 and reunites Dorothy with the humbug Wizard from The Wonderful Wizard of Oz. This is one of only two of the original forty Oz books (with The Emerald City of Oz) to be illustrated with watercolor paintings.
