The Casino began a library in 1867 with a collection of some 446 volumes. This was greatly expanded beginning in 1898. The library was officially renamed and re-opened in 1996 by the children of Carlos Prieto Fernández de Llana (1898-1991). A prominent businessman and lawyer, he was also a member of the Board of Trustees of the Mexican National Symphony Orchestra. He'd actually paid for his law degree with earnings he'd made playing the violin. He also authored numerous books and articles on a wide range of subjects from music to mining and history. The family donated some 2,300 volumes to the current collection. Overall it includes some 14,000 volumes focused on Spanish Mexican relations, humanities, and social sciences. The archive also maintains the art collection of the building as well as other documents and artifacts related to the Casino Español de México. Hours: The library is open to the public weekdays from 10 a.m. to 5 p.m.
