Seven years after the inauguration of the National Museum of the 21st Century Arts and almost seventeen years since the Ministry of Cultural Heritage and Activities started establishing its collections, the MAXXI Arte wishes - with this catalogue - to convey the nature and the import of the work done over the past years. This volume documents all the authors contained in the collection. It is a handy reference tool for researchers and professionals, but also a substantial and significant synthesis of contemporary art production, addressed to the Museum of Art's public.
