Please do not add promotional material to Wikipedia, as you did to Bartolomeo Cristofori. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion. Thank you.

Dear Graham, that wasn't advertising or promotion. It is called updating old bibliographical references. it is sad that Wikepedia is managed by people who do not have the tools to judge what is academic information and what is advertising.
