The Cotsen Children's Library is a unit within the Department of Special Collections at the Princeton University Library.
The Cotsen research collection of illustrated children's books, manuscripts, original artwork, prints, and educational toys from the 15th century to the present day is the benefaction of Lloyd E. Cotsen '50. Fellowships are available through the Department's program of short-term library research grants. The curatorial division hosts academic programs on aspects of the history of children's books and publishes their proceedings. The CCL distributes Cotsen Occasional Press publications based on materials in the research collection's holdings. Additional information and highlights from the collection can also be located on the curatorial blog. Researchers are encouraged to contact the Curator in advance of their visit.
The Cotsen Children’s Library also has a public face, serving as a resource for children, families, librarians and educators. Visitors can explore Bookscape, a picturesque environment with whimsical spaces to read, including a two-story bonsai tree. Cotsen also offers a variety of free programs and events for children, an author interview webcast, and a creative blog.
