The United States at 250

Throughout 2026, the Newberry will be commemorating America’s semiquincentennial—the 250th anniversary of the signing of the Declaration of Independence. Join us this year for a firsthand glimpse at the founding of the United States and for an exploration of the themes that have been present from the late 1700s through today.
The Newberry is proud to be a partner in Illinois America 250, an inclusive, statewide effort to bring together Illinoisans’ diverse perspectives about our history–and our future.
The Newberry features many collecting areas relevant to early American history, from founding documents to Native American history, the westward expansion of the United States, the Civil War and Reconstruction, African American history, and American literature. Our collection materials include over 700 American Revolutionary pamphlets, and Thomas Jefferson’s annotated copy of The Federalist.
*A short narrative of the horrid massacre in Boston: perpetrated in the evening of the fifth day of March 1770. London: W. Bingley, 1770. Case 4A 1151.
Boston, December 17, 1773 : at a meeting of the people of Boston, and the neighboring towns at the Old South Meeting House in Boston… Boston: Edes and Gill, 1773. Vault Ruggles 35.
This very rare broadside gives an account of the dramatic events directly leading to the Boston Tea Party.
This is a reprint of the earlier editions of this narrative, printed in Boston (which the Newberry also holds; see Case E215.4 .B75 1770 and Case F 8441 .097, as well as the newspaper report in Wing broadside ZP 783 .E231). This edition is notable for its large folding frontispiece, derived from the famous Paul Revere image of the “Massacre.”
Journal of the proceedings of the Congress, held at Philadelphia, September 5, 1774. Philadelphia: William and Thomas Bradford, 1774. Vault Ruggles 345.
The first edition of the proceedings of the first Continental Congress, the body coordinating the colonies’ response to the “intolerable acts” imposed by the British in response to the Boston Tea Party.
A declaration by the representatives of the United Colonies of North-America, now met in general congress at Philadelphia: setting forth the causes and necessity of their taking up arms. Philadelphia: William and Thomas Bradford, 1775. Vault Ruggles 346 and Vault Ruggles 347.
The less famous declaration from July 6, 1775, written by John Dickinson after a draft by Thomas Jefferson in the aftermath of the Battle of Bunker Hill. It stops short of declaring independence but insists on the resolve of the colonists to defend their rights.
*Benjamin Stevens, Ticonderoga journal. February 19-May 26, 1776. Vault Case MS 5A 9.
A manuscript journal kept by a Connecticut soldier in the Continental Army defending Fort Ticonderoga in northern New York, including experiences as a prisoner of war captured by the British and their Indigenous allies.
*In Congress, July 4, 1776. A declaration by the representatives of the United States of America, in General Congress assembled…. Newport, RI: Samuel Southwick, July 13, 1776. Case broadside E221 .U57 1776.
Rhode Island broadside printing of the Declaration of Independence, printed just nine days after the 4th. It includes a notorious typo indicating that it was printed on June 13 rather than July 13. These printings of the Declaration predate the engrossed, signed copy that is now thought of as the “original” handwritten document on display in D.C.
Oath of allegiance of the Micmac tribe. 1778. Vault box Ayer MS 3134.
A contemporary manuscript copy of an oath of allegiance to King George III, taken by forty-one representatives of the Micmac or Mi’kmaq people at Mengouèche near Fort Howe (now Saint John, New Brunswick). One of many manuscript documents at the Newberry illustrating the importance of Indigenous people as allies on both sides of the conflict as well as strategic actors for their own interests.
The American Military Pocket Atlas, London: R. Sayer and J. Bennett, 1776, Vault Ruggles 9.
The famous “holster atlas,” designed for use in the field by British military officers and to be carried in pocket (or holster).
Sir Henry Clinton, atlas of battle plans. 1776-1783 (assembled ca 1783). Map4F 3701.S3 (various) and Map 7C 5.
A unique made-to-order atlas of 29 maps and plans for battles during the American Revolution, assembled for British General Henry Clinton.
Arent Schuyler De Peyster, Miscellanies. Dumfries, Scotland: C. Munro, 1813. folio Graff 1057.
This book by a British officer in charge of Forts Detroit and Michilimackinac during the Revolutionary War contains, in a footnote to a poem, the first published reference to Jean Baptiste Point DuSable. The Newberry also holds a letter by De Peyster instructing subordinates to travel to the Illinois country to investigate American sympathizers in 1778; in 1779, DuSable was arrested on suspicion of these charges.
