Book 1

Folklore, legends, myths and fairy tales have followed childhood through the ages. The winged fairies of Grimm and Andersen have brought more happiness to childish hearts than all other human creations. Yet the old time fairy tale, having served for generations, may now be classed as "historical" in the children's library; for the time has come for a series of newer "wonder tales" in which the stereotyped genie, dwarf and fairy are eliminated, together with all the horrible and blood-curdling incidents devised by their authors to point a fearsome moral to each tale. Modern education includes morality; therefore the modern child seeks only entertainment in its wonder tales and gladly dispenses with all disagreeable incident. Having this thought in mind, the story of "The Wonderful Wizard of Oz" was written solely to please children of today. It aspires to being a modernized fairy tale, in which the wonderment and joy are retained and the heartaches and nightmares are left out. L. Frank Baum

Book 2

The Marvelous Land of Oz

by L. Frank Baum

Published 1 January 1920
From the book:In the Country of the Gillikins, which is at the North of the Land of Oz, lived a youth called Tip. There was more to his name than that, for old Mombi often declared that his whole name was Tippetarius; but no one was expected to say such a long word when "Tip" would do just as well. This boy remembered nothing of his parents, for he had been brought when quite young to be reared by the old woman known as Mombi, whose reputation, I am sorry to say, was none of the best. For the Gillikin people had reason to suspect her of indulging in magical arts, and therefore hesitated to associate with her.

The Tin Woodman of Oz

by L. Frank Baum

Published 1 January 1920
The Tin Woodman of Oz: The Tin Man and the Scarecrow are regaling each other with tales of past adventures in the Tin Man's castle in the Winkie Country when a Gillikin boy named Woot wanders into their presence. After he is fed and rested (which the Tin Woodman and the Scarecrow, not being of blood and flesh, do not need), Woot asks the Tin Man how he became made of tin. The Tin Man tells Woot the story of how he had once been a flesh-and-blood woodman in love with a maiden named Nimmie Aimee. Woot suggests that since the Tin Man now has a kind and loving heart, it is his duty to find Nimmie Aimee and make her Empress of the Winkies. The Scarecrow agrees, so the three set off to search for the girl. Will they find her, and if they do, will she still love the Tin Man? This lavishly illustrated edition has more than one hundred illustrations by John R. Neill.
