“Because parchment was expensive and hard to come by, ancient writers would partially efface writings deemed useless/irrelevant and cover them with new words, creating a palimpsest. Barnet refers to adaptation as a ‘palimpsestuous’ act because “the residue or trace of previous writing/staging is inescapable”. But my favorite way she describes a palimpsest is as a haunting. I believe The Wizard of Oz, in both its countless adaptations and its pop culture explosion, perpetually creates its own palimpsest."
