Welcome to ConSource
The Constitutional Sources Project (ConSource) connects hundreds of thousands of American citizens of all ages annually to our nation's constitutional history by creating a comprehensive, easily searchable, fully-indexed, and freely accessible digital library of historical sources related to the creation, ratification, and amendment of the United States Constitution. Our team not only curates important digital collections of historical materials, but also creates free research reports and educational resources — including downloadable lesson plans — to meet the specific needs of scholars and authors, legal practitioners and government officials, educators and students, journalists and the general public.
