Created in collaboration with Alexandra Gillespie’s Old Books New Science Lab at the University of Toronto, Communities of Practice is a SSHRC-funded research project that explores how the multilingual urban bureaucracy of London—the world of Chaucer and his contemporaries—shaped late medieval literature. Bringing together linguistic, palaeographical, literary-historical, and computational methods, the project examines how networks of clerks employed in government offices contributed to the production, circulation, and transformation of literary texts between 1377 and 1471. By pairing innovative machine‑learning techniques with traditional manuscript study, making full use of the increase in digital access to archival documents, the project aims to move beyond linking single documents with individual clerks. Instead, it works towards a broader understanding of the distinctive scribal practices that arose in particular office communities and the role played by these scribal communities in the development of literary culture.
Publications
These publications built the foundation for Communities of Practice, demonstrating the need for an examination of the period covered by the project, making a case for the methods we adopt, and applying those methods to small case studies.

AI Tool
One strand of Communities of Practice is the building of a machine-learning tool that uses computer vision to support expert palaeographers in handwriting attribution, particularly by suggesting the most likely government office in which a scribe worked. In “The Paleographer’s Eye ex machina”, we showcase a preliminary version of the tool through analysis of manuscripts associated with the fifteenth‑century clerk and poet Thomas Hoccleve. Over the course of the project, this tool will be trained on a much larger corpus of documents from the offices of government in London, 1377-1471.
