Found somewhere on the Net:

Well, not an infallibility ‘tax’ as much as a ‘charge’.

Well, not so much a ‘charge’ as a ‘payment’… for use of copyright material.

But, they are definitely words of weight and tone, and, infallible.

The Pope’s speeches are copyright to the Vatican’s own publishing house, Libreria Editrice Vaticana. It seems that anyone wanting to quote the Pope in a publication has to pay for use of his (copyright) words.

We know this because “a publishing house in Milan had to pay 15,000 euros ([A]$24,000) to reprint 30 lines from the first speech by the Pope after his election in April [2005]….”

Of course, as you all know, any ‘work’ is copyright to the author, whether or not published into the world for anyone to view or read. It’s just that not everyone’s words are worth so much as to attract a charge or payment.
