Smithsonian Books publishes a select list of trade nonfiction and illustrated books. Our publishing program covers categories where the Smithsonian's authority is unparalleled, such as history; natural history; science and technology; space, aviation, and military; art; and signature illustrated books, as well as works based on museums, collections, and artifacts. For more than 175 years, the Smithsonian Institution has been guided by its mission of “the increase and diffusion of knowledge," and we build on this powerful tradition in our book publishing. We are distributed by Penguin Random House Publisher Services; our titles are available wherever books are sold.
