This work provides as complete a list as possible of Latin texts written during the early Middle Ages on Celtic territory or by Celts abroad. Each entry adverts to MSS (where appropriate), printed editions, notices in other standard repertories, and bibliographies of secondary literature. The book is an ancillary volume to the Royal Irish Academy's "Dictionary of Medieval Latin from Celtic Sources" project, whose main publications are detailed at http://journals.eecs.qub.ac.uk/DMLCS.
