The College of New Jersey, now known as Princeton University, began its library with personal collections from its early presidents and a significant donation from Governor Belcher in 1755. Originally housed in Nassau Hall, the library's collection was destroyed by fire in 1802 but was gradually rebuilt. Under President James McCosh, the library saw significant improvements, including daily access and a new dedicated building, Chancellor Green Library, which opened in 1875. This modern facility marked a shift in library philosophy, emphasizing accessibility and professional management.

By 1948, the collections had grown, necessitating the construction of the Harvey S. Firestone Memorial Library, which provided open stacks and study spaces. Over the years, Firestone expanded to accommodate the growing volume of materials, now featuring over 50 miles of shelves. Today, Princeton's library system boasts millions of printed works, microforms, and manuscripts across multiple buildings and extensive digital resources.
