Smithsonian Open Access expands free public access to millions of digital items

The Smithsonian’s Open Access portal provides free, unrestricted access to millions of the Institution’s digital items, including photographs, 3D models, and research datasets. The content is available online from the Smithsonian’s museums and research centers and is released under a public-domain waiver to enable reuse without permission.

The portal includes tools for downloading individual files as well as bulk access through an API, and it covers two- and three-dimensional materials across the Smithsonian’s collections. The effort is organized by the Smithsonian Institution and is intended to broaden public access to cultural and scientific resources that the Institution stewards.

Smithsonian Open Access also supplies metadata and machine-readable

Smithsonian Open Access also supplies metadata and machine-readable files to support research, teaching, and creative projects. By offering high-resolution images and 3D scans along with standardized data, the portal is designed to make Smithsonian resources easier to incorporate into academic work, classroom materials, and commercial or nonprofit creative productions.

The online release builds on the Smithsonian’s broader mission to share knowledge and collections widely. The portal’s materials come from a range of the Institution’s museums and research centers, enabling new forms of digital scholarship, local cultural programming, and product or exhibition development that can directly involve Washington, D.C.-based institutions and creators.
