When I was a child, my grandmother used to sing a song to me that she called "The Skeptic's Daughter." Others call it "Rosedale Water" or "On the Banks of Rosedale Water." We lived in east Tennessee, right in the heart of Appalachia, where a lot of songs exist that outsiders never heard of. I have looked for the lyrics of this song for years, and finally found it recently online!
I also learned to knit the continental way on YouTube.
There is a lot to know from people who don't have access to technology, and people who have long since died. It is the people who lived without technology, who grew and preserved their own food and made everything from scratch who we have the most to learn from, IMHO. They are a dying breed.
A friend pointed out recently that books of phosphorus can be altered. She's on a campaign to save paper books, just as others have started seed banks because of hybridization of plants.
