This is part a catalogue of all Latin manuscripts of the works of Beothius, including his translations of Aristotle and Porphyry. The six volumes are arranged geographically and are accompanied by a general index, although each volume is also indexed separately. The conspectus includes fragmentary texts, as witnesses of a once-complete version. Each entry includes a short physical description of the manuscript, a complete list of contents, a note of any glosses present, a brief summary of any decoration, the provenance of the manuscript and a select bibliography for each codex. Particular attention is paid to the use of the manuscripts. Since Boethius was an advocate of artes teaching, these manuscripts give an insight into who was taught what, where, to what level, and in what way.
