The Nationalmuseum in Stockholm, Sweden’s premier art collection, has released over 3000 images of its works in Wikimedia Commons. It joins other institutions which have announced their own open access policies in recent years, including another major Scandinavian collection, the Statens Museum for Kunst in Copenhagen, and the Walters Art Museum in Baltimore, which likewise chose to release its images through Wikimedia Commons.
The Museum of Modern Art has launched an online resource documenting its complete exhibition history. Here you can find installation views, catalogues, checklists, and press releases for over 3500 exhibitions at MoMA from 1929 to the present. Needless to say, MoMA has played a central role in the history of modern and contemporary art, so this comprehensive resource should prove extremely valuable to scholars and students. You can read more in MoMA’s press release and an article in The New York Times.
