In the introduction to his edition of the New Minster Missal (Le Havre, Bibliothèque municipale, 330), Derek Turner tells us that the manuscript he is editing ‘is one of the five fairly complete mass-books of probable English provenance remaining from before 1100, and the oldest true missal’. By ‘missal’ he means, of course, that Le Havre 330 is a mass book of the sort which usually contains a suitably integrated ordering of texts and chants of the sacramentary, the lectionary and the gradual according to the various traditional propers and ordinaries of the temporal and sanctoral arranged to accompany the church year; normally there are also some votive masses after the main corpus of the book.
