Because of financial difficulty, the state of California took possession of the park in 1880, and planned to develop it as a cultural center for the growing community. The State Exposition Building, which was completed in 1912 for permanent exhibition of products and resources for all California counties, became the centerpiece of the renovated park, renamed Exposition Park. The museum's goal was to dramatize contemporary science for people of all ages and to encourage human capabilities. Exhibits were created by world famous scientists, designers, and architects, such as Charles Eames. In 1984, an IMAX theater was added.
Documentation comprises a catalog, an explorers guide, two videos, and grand opening memorabilia.
