What Else Has Been Destroyed?

According to the linked news report, the papers that the pope's butler leaked were papers that the pope had personally indicated as being papers to be destroyed.    This reminds us of the similar case of Archbishop Dziwsz refusing to follow John Paul II's request that his personal papers be destroyed after his death.

Given that we see evidence of at least the two most recent popes attempting to have documentation of their papacy destroyed, one really has to wonder, what else has been destroyed by popes over the years?

Zealous "conservative" RCs have a very rose-colored picture of the papacy.  But the reality is that it is institutionalized corruption.  We have the butler and the archbishop to thank for two peeks into the machinations that go on behind the curtain, but does anyone doubt that this is but the tip of the iceberg?
