Apocalypse and/or Metamorphosis

It seems the five dollar note puzzle has been solved. Anja Farber suggested that 901 B81A looks like a library call number using the Dewey Decimal System, and I must say I've grown to trust her academic ways, especially following her outing of Beltaine as a plagiariser. Cheshire Cat went further, deciphering "SLV" as the State Library of Victoria, and even identifying the book - Apocalypse And/Or Metamorphosis by Norman O. Brown. I will head to the library forthwith and report on my findings.
