Lyman Frank Baum penned fourteen novels in his famous Oz chronology. These can be divided into two distinct sections: the First Chronicles of Oz, published between 1900 and 1910, ended when Oz was believed to be "cut off forever from all the rest of the world," and the Second Chronicles of Oz, whose publication spanned the years 1913 through 1920, reconnected the Royal Historian of Oz to that lost land by means of "wireless telegraphy." Combined, the two halves form the Great Book of Oz. Within this single volume all fourteen novels and a half dozen short stories are presented in sequence, formatted not only for ease of reading, but to emulate the textual structure of that original publication.
