I am not sure what I was expecting from this purchase but I was definitely surprised by its content. It was like opening a time capsule and seeing into what the harp world used to be like before my time. There is even instructions on how to generate programs on early home computers in order to assist with harp making. It wasn't the easiest of things to read from start to finish but I feel as though I benefited from doing so.
