Biblioteca Nacional de Portugal
Founded in 1796, the Biblioteca Nacional de Portugal (BNP) holds the largest historical and cultural bibliographic collection in the country with over 3.5 million items from a wide range of genres, both in print and manuscript. The collection spans from 11th century documents to the personal papers of many Portuguese writers up to present day.
