Providing the critical edition of Augustine's 'sermones ad populum' LXXI-XCIV, this volume complements CC SL XLI Aa ('sermones ad populum' LI-LXX A, 2008) and, in doing so, completes the critical edition of the Church Father's homilies on the Gospel of Matthew. Furthermore, the new volume provides an update of the text critical introduction to all sermons on Matthew that was offered in CC SL XLI Aa. Most sermons of the series LXXI-XCIV were edited for the last time in 1683 by the Maurists; others were critically edited more recently by Germain Morin, Cyrille Lambot, Pierre-Patrick Verbraken, François Dolbeau, Luc De Coninck, Bertrand Coppieters 't Wallant, Roland Demeulenaere, and Gert Partoens. For the present volume, Luc De Coninck and Bertrand Coppieters 't Wallant, assisted by Roland Demeulenaere, have made entirely new editions of most sermons of the first group, and have revised the editions of almost all homilies of the second group. In all cases, this was done on the bases of an extensive study of the manuscripts and with a state-of-the-art knowledge of the stemmatical relations between each sermon's direct and indirect witnesses. The critical editions of four sermons featured in the famous codex Mainz Stadtbibliothek I 9 ('sermones' LXXII auct., LXXXVI, LXXXIX, and XC A) have been procured by François Dolbeau, while Gert Partoens has revised Morin's edition of 'sermo' LXXII A and republished his own new edition of 'sermo' LXXXII.
