Periodic SystemDatabase of Periodic Tables is a wonderful list of periodic tables. No, it is not a periodic table of them, although there are many regularities between the attempts to organise the elements "better". It is so annoying that the underlying patterns of the elements, despite following simple rules, never seem to turn into a perfectly regular diagram that also shows useful properties.
