I am glad that Alcuin Reid has given new life to The Ceremonies of the Roman Rite, and, moreover, that a new edition is called for. But that highly valuable book is not the only thing O'Connell did. I have before me the 1942 edition of his three volume The Celebration of Mass. I very much hope that somebody might do a facsimile reprint of this; or perhaps - someone can inform me - it is available for reading on-line.
It contains a wealth of information about how traditional Western Liturgy was done. It brings back to me memories of Mass-practices in 1967 at S Stephen's House under Derek Allen ... the gentle way he checked whether we really had learned off by heart the texts you need to do from memory; the moment when, doing my best not to trip over my new cassock (fresh from Wolverhampton; what was the name of that man there who had the Staggers trade?) I said Oremus at the foot of the Altar and set off towards it saying the Aufer a nobis only to be stopped dead in my tracks with "No; you start off with your right foot". I don't suppose much of that sort of tuition survives nowadays except in the SSPX and the canonical EF seminaries and at S Stephen's House, God bless it.
TCOM has extensive sections on the role of custom in liturgical law; Votive Masses, Requiem Masses, Missa pro populo ... you name it . Anything that you need to know. Of course, it refers to the EF. But those whose way-ahead is the Reform of the Reform can only benefit by referring to an authoritative book which distilled the experience of centuries of priests developing the ars celebrandi they had received, and then in turn passing it on.
In recent weeks I have drawn attention to gross misstatements of rubrical law relating to the EF both on NLM and Fr Zed. I do not blame them; they were not given a seminary training on the EF before the post-conciliar changes. I was; and that makes mistakes on my part all the more reprehensible. And I would not be in the least surprised if I have given misinformation. Don't trust NLM, don't trust Fr Zed, don't even trust me. Trust O'Connell.
