J. Willard Marriott Library
J. Willard Marriott Library is the main library at the University of Utah in Salt Lake City, Utah. It was named for J. Willard Marriott, the founder of Marriott International. The library building is over 516,000 square feet (47,900 m 2) and houses over 3 million volumes.

The first library was established in 1850 when the school was founded. In 1900 the library was located in the LeRoy Cowles Building on Presidents Circle. In 1935 the library moved to the George Thomas Library Building on Presidents Circle, which now serves as the Utah Museum of Natural History. In 1968 the library moved to its current location and was named for J. Willard Marriott in 1969 when Mr. Marriott contributed $1 million to the University of Utah for library collections. At the time, this was the largest single contribution ever received by the university. In 1996 the library was rededicated after a 210,000-square-foot (20,000 m 2) expansion, which almost doubled the library's size. A major renovation project began in June 2005 and concluded in June 2009. The purpose of the renovation was to improve the seismic stability of the building, provide clearer pathways through the building, improve environmental controls, and allow for more natural light. Several additions were also made to the building including an automated storage and retrieval system that can store up to 2 million items, additional classrooms and teaching labs, additional study areas, a rooftop garden, an advanced technology studio, and a new indoor café.

The library's Special Collections include the papers of Marriner Stoddard Eccles, Chairman of the Federal Reserve from 1934 to 1938; David O. McKay, ninth President of The Church of Jesus Christ of Latter-day Saints; Leonidas Ralph Mecham, Director of the Administrative Office of the United States Courts from 1985 to 2006; and Wallace Stegner, winner of the Pulitzer Prize for Fiction in 1972. The library hosts over 100 unique digital collections, many of which include items from Special Collections. Digital collections include the Mountain West Digital Library, USpace, Utah Digital Newspapers, the Western Soundscape Archive, and Western Waters Digital Library. The Aziz S. Atiya Library, which is located in the Marriott Library, is named after the founder of the Middle East Center, Aziz Suryal Atiya, and is the fifth largest library for Middle East studies in North America.
