The Mark O. Hatfield Library is the main library at Willamette University in Salem, Oregon, United States. Opened in 1986, it is a member of the Hatfield Library Consortium along with several library lending networks and is a designated Federal depository library. Willamette's original library was established in 1844, two years after the school was founded. The library was housed in Waller Hall before moving to its own building (now Smullin Hall) designed by Pietro Belluschi in 1938. The Hatfield library building stands two-stories tall and is located near the center of the campus. The library contains over 350,000 volumes overall in its collections, and includes the school's archives. Designed by MDWR Architects, the red-brick building has glass edifices on two sides and a clocktower outside the main entrance. The building also includes a 24-hour study area, private study rooms, and a classroom. The academic library is named in honor of former Senator Mark O. Hatfield, a 1943 graduate of Willamette and former member of the faculty, and the library houses his personal papers and a collection of his books.
