AY BACK in 2007, Watershed began uploading hundreds of liturgical books which were freely downloaded by Church musicians everywhere. Many of the books were (and remain) extremely rare. One of the most important books we uploaded in 2008 was a complete copy of Dom André Mocquereau’s 1903 Liber Usualis. It seems that archive.org has followed our lead. More than half a decade later, they have scanned their own copy of Mocquereau’sbook, and made it available as a PDF file.
Surprisingly, their scan was poorly done—whereas archive.org usually does a fantastic job. In fact, the Watershed PDF is of a higher quality:
* PDF Download • Solesmes Liber Usualis (1903) — «Paroissien Romain»
—The 1903 Liber Usualis of Dom André Mocquereau.
Liber usualis, Missae et officii
pro Dominicis et festis duplicibus:
cum cantu Gregoriano
Publisher = Romae: Descleé, Lefebvre & Soc.
Typis Societatis S. Joannis Evangelistae
THIS BOOK WAS Mocquereau’s great masterpiece, and it still excellent for reference purposes. Many of his variants are more beautiful than those found in Pothier’s Editio Vaticana, such as the 1903 version of Ut Queant Laxis.
