These pages complete the inventory of Medieval Latin Aristotle Commentaries published in Traditio 23 (1967) 313–413, 24 (1968) 149–245, 26 (1970) 135–216, 27 (1971) 251–351, and 28 (1972) 281–396. The commentaries have been arranged alphabetically according to the author's first name, with a brief bio-bibliographical note and indication of manuscripts and editions. It is to be noted, however, that mention of the manuscripts has been omitted in the entry for Thomas Aquinas in view of the publication now in progress by H. F. Dondaine and H. V. Shooner of Codices manuscripti operum Thomae de Aquino (Rome 1967ff.).
