Enhanced descriptions from Syndetics:

The Wonderful Wizard of Oz is the quintessential American fairy tale. Michael Patrick Hearn, the world's leading Oz scholar, now provides a fascinating new annotation that not only reacquaints readers with the Tin Woodman, Scarecrow, and Cowardly Lion, but also illuminates the colorful background of this treasured American classic. This edition explores numerous contemporary references, provides character sources, and explains the actual meaning of the word "Oz." A facsimile of the rare 1900 first edition appears with the original drawings by W.W. Denslow, as well as 25 previously unpublished illustrations. There is a bibliography of L. Frank Baum's published work, every notable "Oz" edition, and the stage and cinematic productions from 1939's The Wizard of Oz, to the 1974 Broadway hit, The Wiz. A beautiful, awe-inspiring work, The Annotated Wizard of Oz is an enduring tribute to the timeless joy of The Wizard of Oz, and a classic to rival Baum's own.
