JOIN PRESERVING THE WORLD'S RAREST BOOKS

Libraries

Libraries around the world partner with us in order to discover the rarity of their collections. We work with them to identify their rarest books by comparing their holdings with the copies listed in the Universal Short Title Catalogue. Our partners are a number of different institutions, small and large, public and private. Learn how your library can partner with us!

The number next to each library represents which year they joined the project.
