The Walters Art Museum has donated some 19,000 images of works from their collections to Wikimedia. They are among the museums — another is the Getty — who reject the spurious claim of some institutions that they can control the copyright on works that are hundreds of years old. In 2006 they removed admission fees. In 2011 they made 20,000 images available on their website through a Creative Commons license. I endorse this attitude, which promotes the free exchange of ideas and furthers the institution’s educational mission in a dramatic and effective way.
