Nicolaus de Ausmo's work was completed in Milan on 28 November 1444 as a supplement to an older guide to confessors, the Summa de Casibus Conscientiae, written by Bartholomew of San Concordio (1260-1347) about a century earlier, in an effort to keep up with changes to canon law. The first printed edition appeared in 1473, and was subsequently printed in twenty-four other editions during the incunabula period. During the gap between the text's completion and its first appearance in print, this popular manual would only have been available to confessors in manuscript form. Even so, fewer than ten other manuscript copies of the text from this period are recorded in libraries worldwide.
