Universidad Veracruzana — USBI-Xalapa
The Unidad de Servicios Bibliotecarios y de Información at the Universidad Veracruzana modernised its online catalogue with AtoM in 2025. The work followed a long-running notarial-archive project whose earlier consultation software had been developed internally from 2004 and later named Software Archivos Notariales Xalapa y Orizaba. Twenty years after the original service was created, the university identified the need for normalised description, stronger retrieval and interoperable metadata. Its Proyecto AtoM adopted the open-source platform and ISAD(G) to present notarial records dating from 1578 to 1799 alongside personal fonds and photographic collections. The institutional account establishes replacement and modernisation of the earlier catalogue, but it does not describe data extraction, field mapping or an automated transfer; those technical migration details are therefore not claimed.
