I am writing a paper in which I refer to a database maintained by a learned society. Something like:
We performed this analysis on 7,195 structures taken at random from the Poisonous Substances Database  maintained by the Democratic Chemical Society .
Ref. 1 will be the URL of the database, but I am wondering about the learned society: should I include its URL as a reference? Or should I simply not give any citation along with its name?
