Reciprocal representation principles are the basis of the international network of authors' societies. They make it possible for one society to represent the worldwide creative repertoire in their home territory. For example, if a Spanish society and an Australian society have signed a "reciprocal representation" agreement, the Spanish society can represent the Australian society's repertoire in Spain and the Australian society can represent the Spanish society's repertoire in Australia. They grant licenses for uses of each other's repertoires and collect royalties for these uses.
