When I was at an EF Mass at Milton Manor, a Recusant house not far from here, somebody told me that they use Bishop Challoner's Missal. Splendid!! And ... that therefore, when they say a requiem, they use the Common Preface (you will recall that the Preface for the Dead is a recent addition to the Missal).
Not long ago, I was speaking to a FSSP priest about the naming of S Joseph in the Canon. He said that when celebrating with a book that contained it, he named the Saint; when the volume on the Altar lacked S Joseph, he omitted him. [As for the related question of whether S Joseph is canonically in the 1962 Editio Typica, see comments of Fr Michael Brown and of Rubricarius attached to my post of 13 November 2009. This is not what I am discussing today.]
Is this an accepted praxis - to use the book in front of one even if it has been superseded by more recent legislation? Or is it the celebrant's duty to check in advance and to gum/write things in so as to be up-to-date?
(When Urban VIII changed the Breviary Hymns, his decree explicitly accepted the former possibility; he even allowed booksellers to continue to move stock which they had already printed, and purchasers to use the old texts therein. On the other hand, when Pius X changed the Psalter, he insisted on immediate compliance. Is this relevant?)
The question affects me. The more recent of the two Altar Missals I use was printed just after the publication of the new Assumption propers in 1951. It contains them ...on August 15. But, presumably by a printer's oversight, throughout the Octave Famulorum is given for the commemoration.
(Yes, I know Bugnini, cuius animae propitietur Deus, abolished our Lady's Octave in 1955. Don't remind me of that but address the question I pose! It's an important one! It could vastly enhance the market value of old Missals!)
