Ah, I see what you are asking now.
Well, my teacher studied with both Salzedo and Lawrence and definitely taught the Salzedo method.
I actually have all my original beginning materials still so I can list what, other than the things you have already mentioned, I used at the very beginning:
Fun From The First Vol I and II by Samuel Milligan
Christmas Music for the Harp (Simplified) by Dewey Owens
Junior Bach Collection by Pearl Chertok
Imaginations: Tuneful Fun and Recital Pieces to Expand Early Grade Harp Skills for Non-Pedal and Pedal Harps by Doris Davidson
