Welcome...

The Cotsen Children's Library is a very special library within the Department of Rare Books and Special Collections at Princeton University Library.

Our international 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.

The Cotsen Children's Library also has a public face, serving as a resource for children, families, and educators in the greater Princeton area. Cotsen offers a variety of children's programs that are open to the public and free of charge. Visitors are also invited to explore Bookscape, our whimsical children's gallery. Like Cotsen's programs, the gallery is open to the public and free of charge. Please bring your family to relax and read!
