Welcome to the Winterthur Library, an independent research library with a world-class collection dedicated to the understanding and appreciation of artistic, cultural, social, and intellectual history of the Americas in a global context from the 17th to the 20th centuries. We invite you to visit us on-site or online.
Access the digital holdings of our library through the Wintercat online catalog.
Our holdings include rare books, manuscripts, original works of art on paper, ephemera, photographs, the archives of the Winterthur estate and its history as a museum, and more. Collections encompass everything from 20th-century etiquette books by Black leaders, to 17th-century atlases and style guides by European publishers, 18th-century account books of immigrant craftspeople, to extraordinary 19th-century chromolithographed ephemera by leading printers from around the world.
