There are hints here of what Bob Doto was writing about recently with respect to literary theory development, lots of which wouldn't have been seen/known by Adler/Van Doren in 1972. You might appreciate the ideas in intertextuality and rhizomatic philosophy he touches on. There are also hints of connections to Whitney Trettien's work in Cut/Copy/Paste which I'm reminded of as well.
