As on previous occasions, SIARB will publish reports on the congress in its annual journal and will edit and publish at least one session in a volume of the series “Contribuciones al Estudio del Arte Rupestre Sudamericano”. Due to our economic limitations as private scientific society, we cannot publish a large part of the transactions. However, we are in contact with colleagues and other institutions in the neighbouring countries and are confident to receive their support with the publication of other sessions. In this respect, chairpersons of the sessions will play an important part.
