||Snow 1977, no. 88: "Relies heavily on Valmar's commentaries (1889), but the bibliography was very good in its day. Central focus is on the personal nature of the CSM and on the role of Provençal poetry in shaping much of its style. On pp. 193-4 there is a useful listing of the codices of the CSM which have been previously cited and which now must be termed lost."
