The sister-books ( Schwesternbücher), also sometimes called “convent chronicles” or “nuns’ books” ( Nonnenbücher), are a collection of works written by nuns in fourteenth-century female Dominican monasteries in southern Germany, Switzerland, and Alsace. These books were written “by women, for women, about women,” (Lewis 1996), and their content focuses on the community’s history and evidence of its sisters’ exceptional devotion. The sister-books typically include a chronicle of the monastery’s foundation and with a series of vitae (“lives”) or spiritual biographies of spiritually gifted sisters. Nine of these books survive through later fifteenth-century manuscripts and modern (nineteenth- and twentieth-century) editions. Although sometimes attributed to one nun as the book’s writer, the sister-books were likely collectively authored and tend to focus on communal history and spirituality.
