William L. Clements Library

University of Michigan

The William L. Clements Library is a rare book and manuscript repository located on the University of Michigan’s central campus in Ann Arbor, Michigan. Specializing in Americana and paricularly North American history prior to the twentieth century, the holdings of the Clements Library are grouped into four categories: Books, Manuscripts, Graphics and Maps. The library’s collection of primary source materials is expansive and particularly rich in the areas of social history, the American Revolution, and the colonization of North America. The Book collection includes 80,000 rare books, pamphlets, broadsides, and periodicals. Within the other divisions, the library holds 600 atlases, approximately 30,000 maps, 99,400 prints and photographs, 134 culinary periodicals, 20,000 pieces of ephemera, 2,600 manuscript collections, 150 pieces of artwork, 100 pieces of realia, and 15,000 pieces of sheet music.

The Clements Library is visited by over 450 researchers yearly. Patrons include undergraduate students, graduate students, faculty, and scholars from around the world, such as Pulitzer Prize-winning author and historian, David McCullough, who used the library’s collections for the book 1776.


The library's collections are spread across five divisions: the Book Division, the Manuscripts Division, the Graphics Division and the Map Division. The Janice Bluestein Longone Culinary Archive, established in 2002 as a fifth division, moved in 2013 to the Hatcher Library, the special collections section of the University of Michigan Library.

Exhibits showcasing the library's collection are on public display on weekday afternoons. Exhibited materials have included rare books, manuscripts, maps, photographs, and prints. Past exhibition topics include: the history of wine-making in America, the sugar trade in the Atlantic world, sports played in 19th century America, and the War of 1812.

Book Division

The Book Division contains approximately 80,000 books, pamphlets, broadsides, and periodicals. Highlights of the collection include books on the discovery and exploration of North America, colonial American imprints, and books and pamphlets of the American Revolution. Expanding beyond the areas of William L. Clements’ personal collection, the library also holds books on a variety of subjects such as African American history, education, Native American history, politics, religion, sermons and orations, slavery and anti-slavery, the West Indies, and women’s history. The contributions of other collectors, such as the James V. Medler Crime Collection and James S. Schoff Civil War Collection, provide additional subject strengths on certain topics.

Manuscripts Division

The Manuscripts Division cares for approximately 2,600 collections of letters, documents, diaries, financial records, and other materials, with an emphasis on 18th- and 19th-century North America. The division's strengths include Revolutionary War era British-American colonial and military history; the Civil War; 19th-century social and religious reform movements, especially abolition; African American and Native American history; women's history; education; naval and maritime history; health and medicine; travel; business and commerce; and other topics.

William L. Clements began to collect manuscripts in the early 1920s and, with the Library's first director Randolph Adams, acquired many of the cornerstone collections of the manuscripts division, including the papers of British Prime Minister William Petty, 2nd Earl of Shelburne; commanders-in-chief of the Army in North America Thomas Gage and Henry Clinton; abolitionists Angelina Grimké, Sarah Grimké, and Theodore Weld; and others.

Map Division

The map collection has been assembled to document the expansion of geographical knowledge of the Americas from the 15th through the 19th centuries, with particular emphasis on North American military history, frontier expansion, and the history of cartography itself. The Map Division was established to deal with the numerous maps and plans acquired by Mr. Clements in the 1920s, some with important manuscript collections and others through the purchase of existing map and atlas collections, notably that of Henry Vignaud (1830–1922).

The Map Division holds some 30,000 maps and plans, about 1,500 of which are manuscripts. Many of the latter came to the Library with manuscript collections such as the Gage and Clinton papers, which makes the holdings particularly rich in the cartography of the American Revolution. In addition to separate maps, the Clements holds 600 atlases. The map catalog includes all maps in books and atlases.

Graphics Division

The Graphics Division holds prints, photographs, printed ephemera, original artwork, illustrated and non-illustrated sheet music, and realia.

William L. Clements had a modest collection of portrait prints and a few Revolutionary War cartoons when he founded the library in the 1920s but he showed little interest in visual materials. The current Graphics Division, founded in 2002, is made up mostly of materials acquired over the past 30 years. For sheer numbers, the fastest growing part of the Clements Library has been the photograph collection, with fewer than 100 items in the 1970s, and expectations to pass 150,000 by 2015.

The subjects represented by the division mirror the subjects of the other Clements divisions with strengths in American military history, political and social histories, American urban and landscape views, portraiture, satire, popular culture, leisure activities, labor, technology, travel, and culinary history. Examples of almost every printing and photographic process used from the 15th to the 20th centuries exists within the collections.

Approximate numbers for the division holdings:

  • Prints—9400 items
  • Photos—90,000
  • Ephemera—10,000
  • Sheet music—15,000
  • Artwork—150
  • Realia – 100
