The original registry kept by Harry Eisenhauer was only for the DC-13a "Ones Inward", as this note appeared to be a lot scarcer then the DC-13b and DC-13c.
The Carlton catalogue states:
The 2009 CPMS register provides a listing of 1898 $1 Dominion notes with "Ones Inward", DC-13a. As oif the time of publication of this catalogue 114 privately owned examples were recorded. DC-13b and DC-13c are considerably more plentiful, but we are aware of no attempt to compile a census of these varieties.
I agree that a registry for the DC-13b and DC-13c is of minimum value, but the small number of DC-13a notes seen over the years begs the question; "What happened to the 15,200,000 printed ?"
