Bärenreiter has just published a newly revised version of the B-minor Mass (NBA I rev) to update the now partially out-dated and much criticized version contained in the NBA II/1 edition prepared by Friedrich Smend in 1954. In order to make sense of the different numbering systems for movements in the old and new editions, a concordance is necessary to follow scholarly references to these editions. Actually a system which numbers the movements consecutively and continuously from the beginning to the the end is preferable (the system used by Joshua Rifkin in his Breitkopf 2006 edition and by others as well).
The PDF charts should enable the reader to gain a quick overview of the current status of research regarding the sources (the bulk of them being parodies some of which are undisputed and listed and others which are left open as possibilities) and the chronology of the separate movements involved.
The charts should be self explanatory for the most part.
