This volume advances the utility of Morton W. Bloomfield et al., Incipits of Latin Works on the Virtues and Vices, 1100-1500 A.D. (1979) by correcting, supplementing, adding to, or deleting information in this commonly-used reference guide to medieval Latin manuscripts of an ethical or pastoral character. Careful attention is paid to updating the identification of texts and their authorship and references to critical editions of works on the vices and virtues. Many new manuscript witnesses and over 500 new texts are added to those found in the earlier catalogue and a number of short texts on vices and virtues are edited here for the first time.
