This excellent scholarly study is directed to avariety of readers: from church historians toart historians, who previously could turn directly only to the illuminated initials that appearedin two of the six manuscripts of the Amptbuch. In addition to a critical edition, the editor offers here an English translation of TheBook of Duties together with notes. The title reflects the underlying text, which is about the obligations and (sometimes mundane) duties that specific sisters were obliged to perform inservice to their communities.
