The World of Oz

The World of Oz is the complete collection of the fourteen full-length Oz books written by L. Frank Baum and published between 1900 and 1920. Even while he was alive, Baum was styled as "The Royal Historian of Oz" to emphasize the concept that Oz is an actual place. The illusion created was that characters such as Dorothy and Princess Ozma related their adventures in Oz to Baum themselves, by means of wireless telegraph.¿
