## Why They Matter
The significance of José Esteves, as reflected in the source material, lies in his documented presence across multiple bibliographic and authority systems. Inclusion in identifiers such as ISNI, VIAF, and GND is a marker used by libraries, archives, and research institutions to disambiguate authors and link their works across catalogues and databases. This makes any publications, datasets, or teaching-related materials associated with his name more discoverable and reliably attributed. His recorded fields—information systems and software—place him within technical and academic domains where cataloguing and authority control support scholarly communication. As a university teacher, his role is inherently connected to knowledge transfer and training, although the provided sources do not list specific courses or mentorship outcomes. Without these authority records, it would be more difficult to collate his contributions across institutional silos.
