 It aims at bringing something of the past into the future, and at putting it to good use in the present; in this sense can it be said to be, to the highest degree, traditional.

+Its melodies have been critically established using dozens of the most ancient manuscripts; in a few places, as is also the case in the editions of the \emph{Antiphonale Romanum},
 the text of the antiphons differs slightly from that found in the Breviary, heeding the overwhelming consensus of the sources, where such a consensus exists. 
 Antiphons of very recent introduction have been given melodies of the existing tradition of Gregorian Chant.
 
-This book looks up to the horizon of a future authentic restoration of the Roman liturgy; this is, in part, why it uses the text of hymns as before the reforms of pope Urban VIII.

 It is the book proper to the ordinary choir member: it contains everything that an ordinary choir member will sing at Matins, namely, the Invitatory (without its psalm, sung by a cantor), 
 the Hymn, Antiphons, Psalms, and Versicles, as well as the common tones of those parts sung by all.

+This book attempts to enable the Church at large to render unto God a fitting praise in the present; this is in part why it uses rhythmic signs, based on the rules of the \emph{mora vocis}
 and on the rhythmic indications of the adiastematic manuscripts, where they exist, 
 because the faithful are accustomed to these signs more than to reproductions of ancient neumes: a table of equivalence is found below. 
-This is also why this book is laid out so that it may be used by those celebrating Divine Office according to either 1960 or \emph{Divino Afflatu} rubrics.
+This is also why this book is laid out so that it may be used by those celebrating Divine Office according to either the 1960 or \emph{Divino Afflatu} rubrics.
 
 The selection of feasts found in this book corresponds more or less to those of the first and second class in the 1960 liturgical calendar, 
 and to those of \emph{duplex majus} rank and above in the older system;
 but not all \emph{duplex majus} that were downgraded to the third class in 1960 are included.
 
 It is assumed that all users of this book have an \emph{Ordo} prepared for them or by them, and need no indications of which parts to use or omit depending on the rules that apply to them;
-for instance, someone celebrating according th 1960 rubrics would know to use the ferial psalmody, instead of that provided in the present book, on the Decollation of St. John the Baptist,
+for instance, someone celebrating according to the 1960 rubrics would know to use the ferial psalmody, instead of that provided in the present book, on the Decollation of St. John the Baptist,
 it having been downgraded to a third class feast. Therefore, the rubrics given here are minimal.
 
 This book is also, and most importantly at present, a \textbf{draft}. We, the editing team, are entirely too few to bring it up to proper standards by ourselves.
