Katharine Jager Rubinson has also published a book, just last month.  From the Amazon.com description:  "Vernacular Aesthetics in the Later Middle Ages explores the formal composition, public performance, and popular reception of vernacular poetry, music, and prose within late medieval French and English cultures. This collection of essays considers the extra-literary and extra-textual methods by which vernacular forms and genres were obtained and examines the roles that performance and orality play in the reception and dissemination of those genres, arguing that late medieval vernacular forms can be used to delineate the interests and perspectives of the subaltern."  Learn more.
