Our Library

The gallery of the Cotsen Children's Library is currently under renovation, and will reopen in April 2018 after the completion of the Firestone lobby restrooms. Access to the Cotsen research collection will be available as usual to researchers during the temporary closure. Our online children's programming will continue, as well as select Saturday events.

The Cotsen Children's Library is a unit within the Department of Rare Books and 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 strongly 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, a teen writing resource, and a creative blog.

Bookscape is open daily to the public and free of charge. We encourage  visitors of all ages who want to relax and read in a quiet and enchanting setting!
