The three story, 215,000-square-foot (20,000 m2) library is separated into two wings housing different areas on each floor. The building has a total of 5 acres (2.0 ha) of indoor floor space and 50,000 feet (15,000 m) of shelving. The library houses a collection of writings and original letters from Jack London, as well as memorabilia relating to his works.[22] The $41.5 million building is named after Charles M. Schulz, the creator of the Peanuts comic cartoon, and his wife Jean, who donated $5 million to help build and furnish the structure.[23]
