53) To date, there has appeared no definitive study of the complete Mercedarian liturgical or chant traditions before general imposition of the Breviarium romanum of 1568 and Missale romanum of 1570, which were duly adopted by the general chapter of the order at Saragossa in 1576.
Missale secundum ordinem Primatis ecclesie Toletane ([Alcala de Henares], 1550); and Breviarium secundum consuetudinem sanctce Ecclesice Toletance (Lyon: Bartholomaeus Fraenus, 1551).
Breviarium Romanum sub maiori forma expulsis summo labore difformitatum scopulis lipidissime efformatum extat.

The Breviarium notatum Strigoniense today has 328 parchment folios (sometimes mistranslated as "pages" in the commentary of the edition) and one unnumbered folio after folio 155, all with modern penciled numbering.
Since most of this material is missing from the Breviarium notatum Strigoniense, earlier scholars (such as Dom Jean Claire, Carl-Allan Moberg, and Bruno Stablein) assumed that the manuscript was prepared at or near its present location in Prague and that it was Czech and possibly Premonstratensian, as is the Strahov Abbey.
We have seen the importance of such business relations in the printing of the Breviarium
romanum,where Paolo Manuzio acted as publisher to many Roman printers.
