Another way to categorize TRPs oeuvre

[Mark Kohut]

The World History novels. A trilogy.
"V."
"Gravity's Rainbow"
"Against the Day"

The contemorary (or recent past) American novels

--  "C of Lot 49"
----"Vineland"
----new one

The historical American novel
---Mason & Dixon

If we believe, as I do from external info, that TRP was working on ATD
for a long time---since finishing GR, maybe---then he has alternated, roughly, the World Historical novels with the American novels.
