What it is
A single order of mass imposed on the Western church, replacing local uses except those more than two centuries old.
Why it lasted
It standardised Catholic worship for four hundred years, and remains in use as the extraordinary form.
Where to read it
Public domain and free to read in full, though not held here. The archives below have it.
These open a search on each archive rather than a direct link, which is the honest way to point at an edition nobody here has checked line by line.
