Founders Online: The George Washington Papers
“The Papers of George Washington documentary editing project was founded at the University of Virginia in 1968, under then-editor in chief Donald Jackson. While conducting a worldwide document search that eventually netted copies of some 140,000 documents (and is still underway), the project published Washington’s diaries in six volumes (1976–1979), and began publishing Washington’s general correspondence in multiple series in 1983.”

John Adams
Founders Online: The Adams Papers
“The Massachusetts Historical Society established the Adams Papers editorial project in 1954, upon the Adams family’s commitment to donate their extensive collection of correspondence, diaries, and other documents to the Society. This collection is the most comprehensive and historically significant family archive held by an American cultural institution, public or private.”

Thomas Jefferson

“The Papers of Thomas Jefferson is the definitive edition of the papers of the author of the Declaration of Independence, our nation’s third president. Begun in 1943 as the first modern historical documentary edition, the project includes not only the letters Jefferson wrote but also those he received.”

James Madison
Founders Online: James Madison Papers                                                                                                                                                                               “The modern edition of The Papers of James Madison documents the life and times of the Virginia statesman we remember today as the “Father of the Constitution” and the fourth president of the United States. The edition is organized into four series: the Congressional Series (1751–1801); the Secretary of State Series (1801–9); the Presidential Series (1809–17); and the Retirement Series (1817–36). Each series corresponds with one of the major phases of Madison’s public and private life between 1751 and 1836.”
