Biblioteca Nacional de Espana. The Biblioteca Nacional de España is a major public library, the largest in Spain, and one of the largest in the world.
   It is located in Madrid, on the Paseo de Recoletos. The library was founded by King Philip V in 1712 as the Palace Public Library.
   The Royal Letters Patent that he granted, the predecessor of the current legal deposit requirement, made it mandatory for printers to submit a copy of every book printed in Spain to the library. In 1836, the library's status as Crown property was revoked and ownership was transferred to the Ministry of Governance.
   At the same time, it was renamed the Biblioteca Nacional. During the 19th century, confiscations, purchases and donations enabled the Biblioteca Nacional to acquire the majority of the antique and valuable books that it currently holds.
   In 1892 the building was used to host the Historical American Exposition. On 16 March 1896, the Biblioteca Nacional opened to the public in the same building in which it is currently housed and included a vast Reading Room on the main floor designed to hold 320 readers. In 1931 the Reading Room was reorganised, providing it with a major collection of reference works, and the General Reading Room was created to cater for students, workers and general readers. During the Spanish Civil War close to 500,000 volumes were collected by the Confiscation Committee and stored in the Biblioteca Nacio
