Ginsberg seems to refer to pumpernickel as whole rye, which he has as a separate ingredient. Perhaps there is an extra coarse flour?
There doesn't seem to be a standardized way of naming different rye flours. I've figured out white and medium. Bob's Red Mill sells a dark rye, which I use in my Limpa Bread. I'm planning on buying a pumpernickel--not a term he uses for rye flour.
He has a picture of these types: white rye flour, medium rye flour, dark rye flour, fine rye meal, medium rye meal, coarse rye meal, and malted rye berries.
He seems to distinguish between flour and meal.
