Katherine,
 
Henry Littlefield argues WIZARD  as a populist parable  while Fred
Erisman sees it as an investigation of Progressivism
(both in AMERICAN QUARTERLY, l964). Gore Vidal has a nice compendium
review article of books about Oz in the
Sept. 29, l977 NYBR.
 
\The Oz series has attracted such writer/critics as Russell Nye, Marcus
Bewley, Edward Wagenknecht, and  Roger Sale.
