Here we present the project Censo-Guía de fondos y colecciones fotográficas de instituciones públicas de España, Portugal e Iberoamérica (Census-Guide of photographic collections and holdings of public institutions of Spain, Portugal and Iberian-America). This is an initiative promoted by research group Griweb, of the College of Documentation Sciences of Complutense de Madrid University (Spain), whose aim is to disseminate over the internet the photographic heritage conserved in public institutions and centres in Spain, Portugal and Iberian-America. The justification and aims of the project are presented, as is the team responsible for the research.
