Torben - The two conferences were held in 1966 and 1980. The proceedings were published by: Spoleto: Centro italiano di studi sull'alto medioevo as, respectively, vols 14 and 28 (the latter in two parts) of the Spoleto series entitled Settimane di Studio de Centro Italiano di Studi sull'Alto Medioevo. Hope this helps, but come back to me off-list if you need more.
