The Smithsonian is the latest institution to open part of its collection to online visitors. 2.8 million images will now be accessible through an online platform, and enter into the public domain, Smithsonian Magazine reported .

So far, the collection has 2.8 million images from across the Smithsonian's 19 museums, nine research centers, libraries, archives, and even the National Zoo. It also said that it will add 200,000 more images by the end of 2020, with the eventual goal of digitizing its entire 155 million item collection, which also continues to grow.

The Smithsonian joins other museums around the world in digitizing its collections, like the Rijksmuseum in Amsterdam and the Art Institute of Chicago, though digital culture heritage expert Simon Tanner said that the scope of the Smithsonian's project is "unprecedented."
