Since you have posted about this, I feel that the same people who E-mailed me will also E-mail you and send a PDF copy. The book is out of print. However, you might want to include your E-mail to make it really easy on them.
Just note: I doubt there is a PDF of the *first* edition requested, from the 1970s. I actually have the choir/organ copy of that, which I purchased used, as it's part of my collection of Ted Marier hymnals (including Cantus Populi and the Pius X Hymnal) that I've gradually gathered over the years to trace permissions and the evolution of his approach to liturgical music at the parish. The PDF that has circulating samizdat-like is from the more expansive *second* edition from 1983 (second printing, which reflects some corrections; I currently actively use this because my choir still sings from this).
I am not near her, but have a friend who has what I believe might be the edition being sought - is this something she ought to donate, which could be cannibalized and scanned? is it even pulic domain? And to whom would she send it?
I was talking about the book as a whole. The parts that use public domain texts and tunes are, as with any hymnal, public domain, but there is an awful lot (accompaniments/harmonies for most of the service work and almost all of the psalter, for example) and many melodies for the service music) that is (i) created by Dr Marier and John Dunn and other credited authors, and (ii) the engraving, as it were, is also not public domain. Et cet.
Some of the harmonizations and psalm settings were originally published by major music publishers (e.g., Oxford), and they quite possibly would object to reproducing their material without buying the rights.
Don't know where you are, CB, but perhaps you could borrow or at least inspect a copy at a library. WorldCat has a listing of libraries with copies (though records for the various editions seem to be conflated, unfortunately).
