The improvement, structuring, enrichment and public availability of BNE datasets is one of the major lines of work at BNElab.

BNE currently allows data from its bibliographic catalogue and authority file to be downloaded and reused free of charge in XML and MRC formats; from its linked data portals in RDF format, and via the SPARQL access point; and from the Hispanic Digital Library using the OAI protocol for exchange and recollection.

Now we are creating new datasets in more reusable formats such as JSON, CSV, TXT and ODS, available at

Furthermore, any new BNElab developments will be made available as open and reusable code on our GitHub account.
