David Zerkel and others do a great job of providing demos of the Rochut.

Bordogni efforts appear to poop out after the first 14 or so.

I have not seen a reference that matched up the etude numbers to or from one volume to the other.

Or from the Wes Jacobs edition for that matter.

Is there a cross reference available that I have not been able to Google up??

Something that says Rochut 23 = Bordogni 37 for instance??

It sounds as though the Jacobs has the same order as Rochut vol 1 & 2.

Thanks!!
