This is a collection of reference tables that I have been accumulating since I was a child. To some extent, the Wikipedia has rather overtaken this particular project. However, this pre-dates the Wikipedia by a couple of decades! Besides, I rather like having all this stuff in one easy-to-find location. 🙂
I have tried very hard to ensure the accuracy of these tables. However, they are supplied as-is without any warranty, express or implied!
