 The Earl Gregg Swem Library (colloquially Swem Library) is located on Landrum Drive at the College of William and Mary in Williamsburg, Virginia. The library is named for Earl Gregg Swem, College Librarian from 1920-1944. In 2008, the Princeton Review rated William & Mary's library system as the eighth best in the United States. The ranking was based on a survey of 120,000 students from 368 campuses nationwide.
 Detailed discussions of plans for the library were held in 1963 and the groundbreaking ceremonies were held later that year on October 11, 1963, at Phi Beta Kappa Memorial Hall. The actual groundbreaking occurred a few weeks after the ceremonies. The cornerstone of the library was laid on October 22, 1964, and the building was scheduled for completion around December 1965. The building officially opened on January 4, 1966, although it was not fully complete. The official dedication ceremony for the library was held on Charter Day, February 12, 1966. The Tucker-Coleman Room of the library was dedicated on November 11, 1966.
 At the time of its completion, the ground floor of Swem Library contained the Botetourt Gallery, an auditorium, the Omohundro Institute of Early American History and Culture offices, a rare book room, an honors room, a museum, an audio/visual department, a film preview room, and a faculty lounge. The first floor contained a reserve room, an after-hours reading room, a reference department, and typing and meeting rooms. The second floor contained administration rooms, conference rooms, and stacks. There was a fire in the Botetourt Theater in 1972 that destroyed a projection booth. A Micro Computer Lab opened in the library on February 13, 1984.
 Construction officially began on an addition to the front of the library on March 3, 1986, to provide extra stack space, reading areas, administrative offices, and a 24-hour study room and snack area. O.K. James Construction Co. led construction. The addition was dedicated on February 5, 1988. A seven-year renovation and expansion was officially completed in 2005 with rededication ceremonies officially marking the completion on February 5, 2005, during the college's Charter Day weekend.
 The Special Collections Research Center (SCRC) of the Earl Gregg Swem Library of the College of William and Mary defines the history of the university and promotes and preserves the scholarly pursuits of its faculty, students, alumni, visiting scholars, and friends. The SCRC contributes to the college's scholarly reputation by providing the rare books and unique manuscript and archival materials that make primary research possible. The SCRC is located in the Warren E. Burger Special Collections Wing of Swem Library.
 The mission of the Manuscripts area of Special Collections is to provide primary source material for the College of William and Mary faculty, graduate and undergraduate students, and visiting scholars and researchers.
 The Manuscripts Collections are primarily focused on Virginia history from the 17th to the 21st centuries. They include the papers of many famous alumni and individuals who have shaped the course of Virginia and the nation. Among them are:
 The Rare Books Collection is a growing collection that provides research opportunities in many areas of western thought and experience from history to religion and science to art. Like the Manuscript Collections the Rare Books Collection focuses primarily on Virginia history but includes collections that cover many other areas and interests that span the 15th through the 21st centuries.
 The Rare Books Collection is actually made up of many distinct collections which each focus on a particular subject area or a particular period in the history of the book. These libraries include:
 The University Archives is the memory of the College of William and Mary, documenting its history from before the founding in 1693 to the present. The wide variety of materials relating to the college and its people through the years includes official records created in the college's daily operations, photographs, publications, video and audio tape recordings, personal papers and books or articles written by or about past or current William and Mary people, newspaper clippings, scrapbooks, and artifacts.
 The Warren E. Burger Collection consists of the lifetime professional and personal papers and memorabilia of the late Chief Justice Warren E. Burger, as well as of related acquisitions, collected by the college. The Warren E. Burger papers were given to the College of William and Mary by his son, Wade A. Burger in 1996. Warren Burger served as the 20th chancellor of the College of William and Mary from 1986-1993.
 Besides the main building, Swem Library also has several branch libraries on campus.
 There are four campus libraries that are part of Swem, but are housed within their respective departments:
 These libraries are not organizationally part of Swem Library, but, with the exception of the Learning Resource Center, do share the library catalog:
