Record supply


There are five methods for obtaining records:

  • Download from the catalogue: allows you to print the selected record, save them in a local file or send them by email.
  • Download compressed files (formats and mrc mrcxml)
  • Download using optional cliente-servidor Z39.50.
  • Through optional OAI-PMH collection
  • Download of files in other formats and reusable (csv, json, txt, ods) from

The content of all files are updated on a first in the current month.

Catalog data are under the CC0 license, so it is free and does not require prior permission. In any case, the BNE would mention the origin of the records.


Technical difficulties

In exceptional cases, when it is impossible to resolve technical difficulties with one of the previously-mentioned methods, users may submit a direct request in writing to the Biblioteca Nacional de España. This request must clearly indicate the search criteria for the records in question and the purpose for which they will be used.

The request should be sent to:
