The Voynich Ninja

Given Prescott Currier's influence on the analysis of the Voynich text there's really very little of his research out there.

Were the few piece that we have everything he produced, or are there other notes out there waiting to be discovered?

Has anybody ever sought out his papers and checked for more writings on the Voynich manuscript?

I would strongly suspect that we don't have "everything he produced" cuz he must have made a whole crapload of notes, scribbles, etc while doing his research. Would be interesting to see these.
