From Clavis Canonum
A copy of the Collectio Tripartita. It is manuscript H in the Brett/Nowak edition.
The text begins with the Ivonian preface as far as 'querere debeat' (Prol. 142, ending before the list of contents), followed by the Tripartita preface proper. It has the dislocated version of A 2.3-4, 2.26 as in Paris, BnF, lat. 4282 (= Q) and (partially) Alençon, BM, 135 (= A). Written saec. xii med. and later in Italy, where it may have been from the outset; the hand is rather heavy. It is unique in attributing the collection to Ivo of Chartres.
Apparently not online, at least not via BVMM, as of April 2022.
