Unlike a museum built around a single acquired collection, the Archaeological Survey of India holds its material chiefly because it excavated it, which means its holdings are distributed across dozens of regional circles and site museums attached to the monuments and excavations that produced them, rather than gathered into one central building. A find made at a particular stupa, temple complex or Indus Valley site is typically housed at the ASI museum nearest that site, so an object's custodian being recorded as the Survey generally points a reader toward a specific regional institution rather than to a single national building the way a reference to the National Museum in New Delhi does.
This arrangement reflects the Survey's core identity as a research and excavation body first and a museum body second, and it shapes how objects associated with the Survey are described here: where a specific site museum is known, that detail belongs with the object's own entry, while the Survey itself is recorded as the governing institutional custodian, consistent with how it presents its own holdings and how other reference works describe them. The Survey also retains a research and conservation relationship with sites and finds long after excavation closes, so its custodianship of an object can mean active study and monitoring rather than simple storage, a distinction that matters for material still under active archaeological or epigraphic reassessment.
