Christopher Page's book is an extensive work covering an area largely where scholars have nor dared to go. Dom Saunier's book is a translation of his French text of 2003 which was in the final stages of preparation when Dr Berry died. David Hiley's book should not be confused with his previous magnum opus Western Plainchant. It contains much new material.
