Mission Statement

The Constitutional Sources Project (ConSource) exists to increase understanding, facilitate research, and encourage discussion of the U.S. Constitution by connecting individuals — including students, teachers, lawyers and judges — with the documentary history of its creation, ratification, and amendment. Since October 2020 the digital archives and the research underpinning them has been part of The Quill Project at Pembroke College, University of Oxford, and is part of a broader project to study the history of American constitutional law.

An Online Library of Constitutional History

For more than 15 years, ConSource has revolutionized the way people interact with history by democratizing access to the source materials of the U.S. Constitution—letters, journals, newspapers, articles, speeches, and other first-hand records—so that any citizen can research and learn from the document’s rich intellectual history.

The countless letters, speeches and journals of the Framers and later Amenders of the Constitution are housed in hundreds of libraries and archives, as well as in private collections throughout the United States and Europe, and are virtually inaccessible to most of us, whether a fourth grader or a Supreme Court Justice. To address this lack of access, ConSource provides free public access to what is fast becoming the world’s most comprehensive online library of source documents related to U.S. Constitutional history.

But we are not stopping there. Through our Constitutional Index and our merger with the Quill Project at Oxford University, we are providing scholars, legal professionals, educators, and the general public with a full range of cutting edge analytical tools and visualizations to explore these documents. The Quill models of the 1787 Constitutional Convention and the Bill of Rights, for example, reconstruct months of negotiation and debate across dozens of committees and subcommittees, allowing the precise context of each proposal, speech, and vote to be explored. Users are able to chart how particular language emerged over weeks and months, and to trace the influence of particular individuals and delegations.

ConSource also creates research reports and educational resources to promote understanding and to meet the specific needs of scholars and authors, legal practitioners and government officials, educators and students, journalists and the general public. By connecting individuals to and facilitating discussion around the diverse ideas and documents that established the United States and have informed our progress, ConSource and the Quill Project are ensuring that future generations will understand the principles of liberty espoused by the Declaration of Independence and enabled by the Constitution and its Amendments.

Volunteer and Research Opportunities

Both the Quill Project and ConSource have had traditions of creating short-term research positions and internships, as well as finding ways to involve broader communities in their research project. Now that the ConSource collection has become part of the Quill Project, we will continue to find ways that let individuals contribute substantively to the understanding of constitutional history.

The Quill Project

As of October 2020, ConSource is part of the Quill Project at Pembroke College, Oxford.

The staff of the Quill Project can be found on the Quill Project Webpages The Director of the Quill Project is Dr Nicholas Cole.

Advisory Board & Note of Appreciation

In October 2020, the Constitutional Sources Project completed a merger with the Quill Project at Pembroke College, Oxford University. We are currently in the process of reconvening the Advisory Board to reflect the changes to the organizational structure resulting from this merger.

We hope that many of those who have been involved in the leadership of ConSource in the past will continue to be involved. In particular, we would like to express our appreciation to the outgoing Board of Directors, Gene Schaerr, Randall Guyann, Michael C. Maibach, Maeva Marcus, Rayman Solomon, and Steven Steinbach, and to the former Executive Director Julie Silverbrook for their whole-hearted investment in ConSource over so many years and for their efforts to ensure a seamless transition period.
