Arquivo Público de Mato Grosso (APMT)
The Arquivo Público de Mato Grosso uses AtoM as its official online research service. The Mato Grosso government service catalogue directs students, researchers and the general public to the AtoM site for immediate, free searching of the state archive's holdings. Populated browse pages contain extensive hierarchical descriptions and digital objects from government, judicial, photographic and private collections. In 2024 the archive also published its thematic Repertoire on the War with Paraguay through the service, following selection, conservation, description, digitisation and indexing by its staff; that collection was subsequently registered in UNESCO's regional Memory of the World programme. These sources establish a substantial operational adoption rather than a generic or empty homepage. They do not identify when AtoM first entered production or describe a migration from an earlier catalogue, so no launch year or legacy source system is asserted.
