The early Irish glossaries Sanas Cormaic (Cormac’s Glossary), O’Mulconry’s Glossary (De origine scoticae linguae), Dúil Dromma Cetta (the Collection of Druim Cett) and the shorter texts Loman and Irsan are important resources for our understanding of the literary and cultural environment of medieval Ireland. These inter-related texts, compiled from the seventh or eighth century onwards, comprise several thousand headwords followed by commentary that ranges from single-word explanations to extended narratives running to several pages. This collection comprises XML files for each version of each text, derived from the Early Irish Glossaries Database: https://www.asnc.cam.ac.uk/irishglossaries
