The ICCM international conferences are organized once every three years. Since 1977, the ICCM organised twelve International Conferences around Europe and North Africa, and a number of Round Tables. All conference proceedings have been published, with the exception of those of Meknes, and the most recent one at Alghero, along with fourteen Newsletters. In this way, the ICCM has contributed significantly in the improvement of the quality of literature on mosaic conservation. Moreover, at the end of each conference, a series of Recommendations and evaluations are made. These are widely disseminated amongst conservators, archaeologists and other interested parties and contribute to setting the standards of contemporary conservations principles.
