The Winterthur Library was established in 1952 to furnish staff, students, and the general public with research materials about American decorative arts. Since then it has become a recognized research center for advanced study and is dedicated to the understanding and appreciation of America's artistic, cultural, social, and intellectual history from colonial times into the twentieth century.

The bookstore follows in this tradition by offering a broad selection of books on gardens, furniture, decorative arts, textiles, and ceramics gives insight to the tales of Winterthur's owners and the home's architecture, collections, and gardens.
