Répertoire International d’Iconographie Musicale (RIdIM)As the international index of visual sources of music, dance, theatre and opera, RIdIM has pursued dual aims since its establishment: firstly, it is charged with the cataloguing of visual sources of subject matters referring to music, dance, theatre and opera; and, secondly, it functions as a framework for their interpretation. Thus, the main objective of RIdIM is the development of methods, means and research centres for the classification, cataloguing and study of iconographical sources related to music, dance, theatre and opera. It is designed to assist performers, historians, librarians, instrument makers, record manufacturers and book publishers, among others in making the fullest use of visual materials for scholarly and practical purposes.
