"That good youth, recognizing the dangers in which he was involving himself in so perilous a journey, declared at his departure that the desire of serving God was leading him into a country where he surely expected to meet death." — Fr. Jerome Lalemant, speaking of St. Jean de Lalande

“Unfortunately, on the one hand a deadly error in judgment placed the official leadership of this committee into the hands of a man who—though generous and brave—was not very knowledgeable: Cardinal Lercaro. He was utterly incapable of resisting the maneuvers of the mealy-mouthed scoundrel that the Neapolitan Vincentian, Bugnini, a man as bereft of culture as he was of basic honesty, soon revealed himself to be.”
— Fr. Louis Bouyer, an important member of the Consilium

A BRIEF HISTORY OF THESE BOOKS:   Dr. Daniel T. Politoske, Professor Emeritus of Musicology at the University of Kansas, was possibly the only person in America to possess seven (7) volumes of the Nova Organi Harmonia. In 2002, he graciously granted Jeff Ostrowski permission to copy these precious books. In 2008, Corpus Christi Watershed had these books scanned and uploaded them to the internet for all to enjoy. Since that time, the NOH has been downloaded many thousands of times.

N.B.   An original volume still needs to be scanned. Also, several volumes donated by Janet Gorbitz need to be scanned, using better technology. If you can donate for this purpose, please notify us by means of the “Contact” button at the top of the page.
