Their official website, si.edu, is the go-to destination for visitors looking for information about the collections, ongoing research, and events taking place across the Smithsonian's 19 museums, 9 research centers, and affiliates around the world.

In terms of technical details, si.edu is hosted by the Smithsonian Institution itself, reflecting the organization's commitment to maintaining control over its own digital presence. The site is hosted under the .EDU top-level domain, which is reserved for educational institutions in the United States. This choice of domain reinforces the Smithsonian's role as not simply a museum or collection of museums, but as an entity that values research, education, and public outreach.
