• I just noticed that Mass XVII in the PBC is not the same as Mass XVII in the Liber usualis. Can someone fill me in on why this is?

    It is the same. It's just that the Graduale Romanum (1908, 1961, 1974, any of them) and the Liber Usualis give more than one option for the Kyrie of that Mass, while the PBC only has the most popular one.
  • Well, that's it then. I just had the first Kyrie copied into a previous Mass program. Thanks.
