The Smithsonian Institution Libraries consists of 20 branch libraries that house a collection of 1.5 million printed books and manuscripts. The libraries handle rights and reproductions inquiries for the Smithsonian. Through the Galaxy of Images website, the libraries provide public access to digital images that can be used for products, books, documentaries, and advertising. The Smithsonian partners with vendors to develop products featuring library images, such as notecards, calendars, and framed prints. The Smithsonian also works with image licensing companies like Corbis to provide worldwide access and distribution of library images while maintaining control over their use.
