“The Duchamp Research Portal is an online platform that aggregates a selection of digitized archival holdings and museum collections at three partner institutions to make a significant portion of primary source materials related to Marcel Duchamp accessible and discoverable through a single interface.  Marcel Duchamp (1887–1968) was one of the most influential artists of the modern era. He changed the way we think about art. Duchamp’s work—which includes paintings, sculptures, prints, and readymades—represents a legacy that informs our understanding of the development of modern and contemporary art. The Duchamp Research Portal unites a number of museum collections and archival repositories related to the life and work of Marcel Duchamp. Making up for the geographic distances between the participating institutions, this online resource digitally aggregates Duchamp-related archival materials along with his artworks and renders them accessible, discoverable, and usable for the Duchamp research community, scholars, and the broader public in a way that has never been possible before. The portal is divided into two sections: Documents and Museum Collections. The two sections of the site reflect the partnering institutions’ administration of the materials. Documents feature items maintained by library and archives departments as well as the Association Marcel Duchamp, while Museum Collections include objects in the partners’ permanent artwork collections. The portal currently consists of nearly 50,000 images of digitized archival documents and related metadata. The materials include correspondence, drawings, technical plans, photographs, exhibition ephemera, newspaper clippings, scholarly articles, and more. These archival resources offer users throughout the world a unique window into Duchamp’s life and artistic production. Please note that the portal does not represent complete and exhaustive access to all Duchamp materials held at the three participating institutions – Philadelphia Museum of Art / Centre Pompidou / Association Marcel Duchamp.”
