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.

I received an email from Jeremy Sachs saying:
"Gelest don't seem to offer [this periodic table formulation] anymore, and because their version heavily modifies Hyde's original table, I've reproduced the 1975 version of his table with the permission of his surviving relatives."
