Wikidata-Enhanced Authority Records: A Project for Personal Names in SBN

The catalogue of the National Library Service (SBN), developed and expanded through cooperative cataloguing, has experienced exponential growth over time. Currently, the titles archive contains over 21 million records, while the authors archive includes around 4,200,000 entries. However, not all authority records in SBN meet the level of completeness and accuracy required of a national catalogue. As part of the collaboration between Wikimedia Italy and ICCU, a project was launched to enrich a portion of the authority records related to personal names in SBN that lacked information. This enrichment was made possible thanks to data available on Wikidata, where many records include the SBN identifier. The number of entries in Wikidata associated with SBN identifiers is expected to grow further, also thanks to ICCU's recent decision to make all records related to personal and corporate names in the Index visible in the SBN OPAC, regardless of their authority level.
