Smithsonian Open Access
si.edu/openaccess
Free access to millions of high-resolution images and 3D models from the Smithsonian Institution's collections, all released for unrestricted use.
Why it is useful
Makes the holdings of one of the world's largest museum networks freely downloadable at full resolution with no licensing restrictions — a direct benefit to designers, educators, and researchers. The 3D scans of artifacts are especially rare; few institutions offer this level of access. Covering everything from moon rocks to butterfly specimens, the breadth is unmatched.
