Preserving American Freedom is a digital history project that explores the complicated history of American freedom through 50 documents in the collections of the Historical Society of Pennsylvania. Detailed transcriptions and annotations of the 50 documents, spanning from 1655 to 1978, are presented alongside digital facsimiles of the originals and contextualized by historical essays, biographies, graphic materials, and tools for educators. This project has been made possible by a grant from Bank of America.
