Welcome to ConSource
ConSource is a free online library of constitutional history. We digitize and cross-reference source documents written by individuals who drafted, ratified, and influenced the creation of the U.S. Constitution and its Amendments. We also run programs and host events that make use of constitutional sources.

ConSource maintains an official library and an open library. The official library contains collections and documents that have been approved by a board of academic advisors who specialize in U.S. history and constitutional themes. The open library contains collections and documents that are being considered or do not meet the standards of the academic advisory board.
As we build the next phase of ConSource.org, anyone will be able to participate in content creation and editing by signing up for a ConSource account. While the next phase of development is awaiting funding, you can still help improve and add to ConSource content.Read more »
