The INTERNET Database of Periodic Tables
There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach.
A Homeopathic Periodic Table by Jan Scholten.
From his book Geheime Lanthanide (Secret Lanthanides) 2006. The basic idea is that successive elements in each series ( = row) are like the stages in a heroic story like the labours of Hercules or the voyages of Odysseus, each one appropriate to meet a different challenge.
