References for Individual Rules

In the database I have attempted to make a reference to each rule, such as a web page link or a reference to an article in the Journal of the Oughtred Society, etc. Many references that were entered a few years ago should be updated and I hope to get to those soon; but perhaps the ones here can give a starting point for each rule in the collection.
