The Swiss National Library collection includes an extensive collection of books, newspapers, maps and atlases, official publications and printed music. The National Library's book collection contains the entire output of Swiss publishers in all languages and adds almost 15,000 new publications in a given year. There is no legal deposit law in place but rather an agreement with Swiss publishers. As of 2020, the library held 4.8 million publications. Special collections that are housed at the National Library include the Lüthi Bible Collection, musical estates, the Archives of the New Helvetic Society and many more collections on topics including library science, press and radio, politics, sports, science and genealogy.
