Among the restrictions Clements placed upon the library was that it should remain separate from the University's greater library system and be governed by an independent board of trustees. Today, this distinct governing structure remains in place, but the library's holdings are integrated into the University Library's Mirlyn catalog. From 1935 to 1945 Howard Henry Peckham was manuscript curator, during which time Clements Library was acquiring collections that established an international reputation for itself as an institution for the study of the Revolutionary War and British Colonial America. 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. 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. 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.
