I'm headed to bed, but will check my OF Antiphonale Romanum II for you in the morning.

In the meantime, here's some background on discrepancies one encounteres in the OF chanted Office. Mr. van Roode's booklet follows the 1983 Ordo Cantus Officii. The Antiphonale Romanum II follows an as yet unreleased revision to the OCO. Les Heures Gregorienne does odd things on Sundays and solemnities, but I have a small hunch it follows the unreleased revised OCO for the four-week Psalter in Ordinary Time.

One can also piece together the Benedictus and Magnificat antiphons in the unreleased revised OCO by consulting the Antiphonale Monasticum I, II, III, released by Solesmes around 2006-2008. They correspond almost exactly to those in the Antiphonale Romanum II. Obviously, because the Benedictine OF Office still includes all the psalms in a one-week Psalter, it is of much less help in trying to deduce the unreleased revised OCO Psalter.

The Canticle from Revelation at II Vespers is included in various (all or nearly all) modes as a tropary (the form it resembles in the spoken Office) in the Antiphonale Romanum II. If this is something that interests you, you will not be disappointed by obtaining a copy!

Thanks, Steven.

I should add that, in this case, AR II follows exactly the antiphons given in the Liturgia Horarum (the recited Office in Latin). I've been putting together a chart detailing these differences in an attempt to make my own best choices, and I've found a tendency toward (but this is not consistent) matching more closely the antiphons of the Liturgia Horarum in the changes made to the revised OCO as demonstrated in AR II, the Gospel canticle antiphons of AM I-III, and (I suspect) the four-week Psalter of HG.

I believe they may be waiting until the official books that will follow the OCO can be published so that changes may be made up to the moment of publication, should they (Solesmes and/or the CDW) choose to do so. Frustrating, I know, but there's nothing we can do.

I believe I'm correct in saying that the 1983 OCO, which frequently includes options for Lectionary cycles A, B, and C, at the Gospel canticles, predates by a few years when these were introduced into the actual Liturgia Horarum, and from all the anecdotes I've heard, different groups in Rome working on these kinds of projects don't always communicate well with one another. Perhaps this is also some of the concern here in releasing the revised OCO before the books.
