Jonathan Edwards' System of Information Storage

Jonathan Edwards when he was about 19 years old 19 or 20 years old he began a system that for lack of a better term it was his informational storage in retrieval system. He devised a system called his miscellaneous and that this probably refers to the YouTube video that you saw of mine where I was trying to explain how he did this. Basically Edwards took a series of notebooks just blank ordinary notebooks some of them he made himself out of just loose paper or materials that he had but they were cross-referenced in a number of ways so it gets pretty complicated because he didn't have a computer.
