The library’s primary nucleus is that belonging to the Querini family. Enhanced over the centuries, today it is a collection of great significance. It contains approximately 1,300 manuscripts, 42,000 antique printed books, including 100 works from the fifteenth century, some of them rare or unique, 3000 prints, atlases, more than 350 geographical maps and cadastral maps. The family’s private archive holds documents, drawings and letters, and is a source of great interest because it sheds light, also from a private perspective, of how politics and business was carried out by the Venetian patrician class from the fifteenth to the nineteenth century.  To consult the archival collection, write to: biblioteca@querinistampalia.org
