Museu Histórico Nacional — Arquivo Histórico

The Arquivo Histórico of Brazil's Museu Histórico Nacional uses AtoM to provide online access to information about its archival collections. The museum's official research page describes a holding of more than 62,000 manuscript and iconographic documents and directs users to its AtoM database for online consultation. The service complements the museum's reference procedures for researchers and exposes collection information and digital representatives through a standards-based archival interface. This is sufficient evidence of formal operational adoption by the museum, but the available institutional page does not state that more than 170 collections were consolidated from fragmented finding aids, give a launch date or describe a migration from prior cataloguing software. The case is therefore recorded as a bounded adoption with the collection size and access function supported directly by the museum.
