On February 7, 2017, Merkley announced a partnership between Creative Commons,[16] Wikimedia Foundation[17] and The Metropolitan Museum of Art where the museum released 375,00 images under a public domain dedication Creative Commons Zero, known as CC0. As part of the announcement, Creative Commons also released the beta of CC Search which included social features for list sharing and simple attribution.[18] The search engine, currently in BETA, pulls Creative Commons licensed images from The MET, Flickr, 500px, Rijksmuseum, the New York Public Library.[19]
