OZ

A pataphor is an extended metaphor...

Or perhaps a scholarly obsession?

"I am pleased to announce the official online release of a project
that it has taken me more than three years to complete: a compilation
of the Book of Current Focus (BCF) discussions from the email digest
groups The Ozzy Digest, Nonestica, and Regalia examining all of the
original 40 Oz novels by L. Frank Baum, Ruth Plumly Thompson, John R.
Neill, Jack Snow, Rachel R. Cosgrove, and Eloise Jarvis McGraw and
Lauren McGraw....Reading through the BCF discussions is the
equivalent of taking a sprawling college literature course on the Oz
books. And who among us has never wished that such a class were
available somewhere? ...(L. Frank Baum would have been astonished at
the sheer magnitude of the analysis of his work and that of his
successors. I hope that this resource will prove
useful as a scholarly tool."
