Spanish bibliography. Monographs (2007-present)

The Spanish Bibliography of Monographs collects the bibliographic records of the books that enter the National Library through the Legal Depository. It contains bibliographic records of printed monographs and electronic resources of textual and multimedia content that are subject to legal deposit. It does not include early childhood and primary school textbooks or publications considered minor. On the one hand, the data are presented in original format (MARC and MARC-XML), ISO 2709: format of exchange and integration of bibliographic information in automated environments). And on the other hand, the data mapped in CSV, JSON, ODS, TXT and XML formats. To publish these data sets, a mapping of the records in our catalog, encoded at source in MARC format, has been done. For each type of record, a series of MARC fields and subfields to retrieve and display have been established, and a literal has been defined to describe the data being displayed. In addition, to respect the navigation functionalities of the Spanish Bibliography online, a number of specific fields have been established that help the filtering of records.
