The Norton Simon Museum, which comprises more than 11,000 objects, contains a significant permanent collection which is highly regarded internationally. The museum itself does not own the works it displays; instead, most of the art is on long-term loan from The Norton Simon Foundation and the Norton Simon Art Foundation, which each own different groups of artworks. As of 2014, their public filings placed the combined fair-market value of the artworks at about $5 billion. The museum makes relatively little effort to expand the collection amassed by its founder, but it still receives gifts. However, no more than 800 or 900 of those pieces are on display at any one time. The museum also mounts temporary exhibitions that focus on a particular artist, an art movement or artistic period, or art that was created in a specific region or country.
