I found a website specifically about superheavy elements: www.transfermium.net. Interesting.

I have looked at that, certainly is not updates that often though, at least not within the past year. For example the nuclide table still has the incorrect properties of ²⁶⁶Sg nor the data on ²⁶³Hs.

One thing I have noticed is data from experiments done can get "lost". That is they never get reported in a peer review journal but are reported only in either theses, conferences, or private communications. So data on decay properties in databases such as ENSDF at NNDC can be rather incomplete relative to experiments that have been performed. In some cases the experiments in question are 5+ years old.  A detailed study on ²⁶¹Sg and its decay products at GSI from a few years back that only appeared in a thesis is a good example of this.
