I mentioned the Catastrophe of Catholic Copyrights before. One of those energetic Americans (sigh, Americans, don't they realise you can't get anything done?) has set up a petition for the Holy See to lift copyright restrictions (not completely, under all circumstance, read the post) on many of the documents it owns.
I sometimes wonder if copyright is the reason for the constant fiddling. Is the 1962 Missal sufficiently innovatory to mean it is protected by copyright in the way that the 1570 Missal is not? Does that undercut any claim that it is traditional in the theological sense? Does anyone else care? (don't know; don't know, probably not).
